+<p>In many big systems, distributed and especially microservice architectures become more and more popular. With the increase of modules and services, one incoming request could cross dozens of service. How to pinpoint the issues of the online system, and the bottleneck of the whole distributed system? This became a very important problem, which must be resolved.</p>
+<p>To resolve the problems in distributed system, Google published the paper “Dapper, a Large-Scale Distributed Systems Tracing Infrastructure”, which mentioned the designs and ideas of building a distributed system. Many projects are inspired by it, created in the last 10 years. At 2015, Apache SkyWalking was created by Wu Sheng as a simple distributed system at first and open source. Through almost 3 years developments, at 2018, according to its 5.0.0-alpha/beta releases, it had alread [...]
+<p>At the early of this year, I was trying to build the Butterfly open source APM in .NET Core, and that is when I met the Apache SkyWalking team and its creator. I decided to join them, and cooperate with them, to provide .NET Core agent native compatible with SkyWalking. At April, I released the first version .NET core agent 0.1.0. After several weeks interation, we released 0.2.0, for increasing the stability and adding HttpClient, Database driver supports.</p>
+<p>Before we used .NET Core agent, we need to deploy SkyWalking collector, UI and ElasticSearch 5.x. You can download the release versions at here: <a href="http://skywalking.apache.org/downloads/">http://skywalking.apache.org/downloads/</a> and follow the docs (Deploy-backend-in-standalone-mode, Deploy-backend-in-cluster-mode) to setup the backend.</p>
+<p>At here, I are giving a quick start to represent, how to monitor a demo distributed .NET Core applications. I can say, that is easy.</p>
+<blockquote>
+<p>git clone <a href="https://github.com/OpenSkywalking/skywalking-netcore.git">https://github.com/OpenSkywalking/skywalking-netcore.git</a></p>
+</blockquote>
+<blockquote>
+<p>cd skywalking-netcore</p>
+</blockquote>
+<blockquote>
+<p>dotnet restore</p>
+</blockquote>
+<blockquote>
+<p>dotnet run -p sample/SkyWalking.Sample.Backend
+dotnet run -p sample/SkyWalking.Sample.Frontend</p>
+</blockquote>
+<p>Now you can open http://localhost:5001/api/values to access the demo application. Then you can open SkyWalking WebUI http://localhost:8080</p>

- <p>Translated by Sheng Wu.</p>
-<p>In many big systems, distributed and especially microservice architectures become more and more popular. With the increase of modules and services, one incoming request could cross dozens of service. How to pinpoint the issues of the online system, and the bottleneck of the whole distributed system? This became a very important problem, which must be resolved.</p>
-<p>To resolve the problems in distributed system, Google published the paper “Dapper, a Large-Scale Distributed Systems Tracing Infrastructure”, which mentioned the designs and ideas of building a distributed system. Many projects are inspired by it, created in the last 10 years. At 2015, Apache SkyWalking was created by Wu Sheng as a simple distributed system at first and open source. Through almost 3 years developments, at 2018, according to its 5.0.0-alpha/beta releases, it had alread [...]
-<p>At the early of this year, I was trying to build the Butterfly open source APM in .NET Core, and that is when I met the Apache SkyWalking team and its creator. I decided to join them, and cooperate with them, to provide .NET Core agent native compatible with SkyWalking. At April, I released the first version .NET core agent 0.1.0. After several weeks interation, we released 0.2.0, for increasing the stability and adding HttpClient, Database driver supports.</p>
-<p>Before we used .NET Core agent, we need to deploy SkyWalking collector, UI and ElasticSearch 5.x. You can download the release versions at here: <a href="http://skywalking.apache.org/downloads/">http://skywalking.apache.org/downloads/</a> and follow the docs (Deploy-backend-in-standalone-mode, Deploy-backend-in-cluster-mode) to setup the backend.</p>
-<p>At here, I are giving a quick start to represent, how to monitor a demo distributed .NET Core applications. I can say, that is easy.</p>
-<blockquote>
-<p>git clone <a href="https://github.com/OpenSkywalking/skywalking-netcore.git">https://github.com/OpenSkywalking/skywalking-netcore.git</a></p>
-</blockquote>
-<blockquote>
-<p>cd skywalking-netcore</p>
-</blockquote>
-<blockquote>
-<p>dotnet restore</p>
-</blockquote>
-<blockquote>
-<p>dotnet run -p sample/SkyWalking.Sample.Backend
-dotnet run -p sample/SkyWalking.Sample.Frontend</p>
-</blockquote>
-<p>Now you can open http://localhost:5001/api/values to access the demo application. Then you can open SkyWalking WebUI http://localhost:8080</p>

+<p>Distributed tracing is a necessary part of modern microservices architecture, but how to understand or use distributed tracing data is unclear to some end users. This blog overviews typical distributed tracing use cases with new visualization features in SkyWalking v6. We hope new users will understand more through these examples.</p>
+<h2 id="metric-and-topology">Metric and topology</h2>
+<p>Trace data underpins in two well known analysis features: <strong>metric</strong> and <strong>topology</strong></p>
+<p><strong>Metric</strong> of each service, service instance, endpoint are derived from entry spans in trace. Metrics represent response time performance. So, you could have average response time, 99% response time, success rate, etc. These are broken down by service, service instance, endpoint.</p>
+<p><strong>Topology</strong> represents links between services and is distributed tracing’s most attractive feature. Topologies allows all users to understand distributed service relationships and dependencies even when they are varied or complex. This is important as it brings a single view to all interested parties, regardless of if they are a developer, designer or operator.</p>
+<p>Here’s an example topology of 4 projects, including Kafka and two outside dependencies.</p>
+<p><img src="./demo-spring.png" alt=""></p>
+<p align="center">Topology in SkyWalking optional UI, RocketBot</p>
+<h2 id="trace">Trace</h2>
+<p>In a distributed tracing system, we spend a lot of resources(CPU, Memory, Disk and Network) to generate, transport and persistent trace data. Let’s try to answer why we do this? What are the typical diagnosis and system performance questions we can answer with trace data?</p>
+<p>SkyWalking v6 includes two trace views:</p>
+<ol>
+<li>TreeMode: The first time provided. Help you easier to identify issues.</li>
+<li>ListMode: Traditional view in time line, also usually seen in other tracing system, such as Zipkin.</li>
+</ol>
+<h3 id="error-occurred">Error occurred</h3>
+<p>In the trace view, the easiest part is locating the error, possibly caused by a code exception or network fault. Both ListMode and TreeMode can identify errors, while the span detail screen provides details.</p>
+<p><img src="span-error.png" alt=""></p>
+<p align="center">ListMode error span</p>
+<p><img src="span-error-2.png" alt=""></p>
+<p align="center">TreeMode error span</p>
+<h3 id="slow-span">Slow span</h3>
+<p>A high priority feature is identifying the slowest spans in a trace. This uses execution duration captured by application agents. In the old ListMode trace view, parent span almost always includes the child span’s duration, due to nesting. In other words, a slow span usually causes its parent to also become slow. In SkyWalking 6, we provide <code>Top 5 of slow span</code> filter to help you locate the spans directly.</p>
+<p><img src="top5-span.png" alt=""></p>
+<p align="center">Top 5 slow span</p>
+<p>The above screenshot highlights the top 5 slow spans, excluding child span duration. Also, this shows all spans’ execution time, which helps identify the slowest ones.</p>
+<h3 id="too-many-child-spans">Too many child spans</h3>
+<p>In some cases, individual durations are quick, but the trace is still slow, like this one:</p>
+<p><img src="top5-not-clear.png" alt=""></p>
+<p align="center">Trace with no slow span</p>
+<p>To understand if the root problem is related to too many operations, use <code>Top 5 of children span number</code>. This filter shows the amount of children each span has, highlighting the top 5.</p>
+<p><img src="too-many-child.png" alt=""></p>
+<p align="center">13 database accesses of a span</p>
+<p>In this screenshot, there is a span with 13 children, which are all Database accesses. Also, when you see overview of trace, database cost 1380ms of this 2000ms trace.</p>
+<p><img src="database-long-duration.png" alt=""></p>
+<p align="center">1380ms database accesses</p>
+<p>In this example, the root cause is too many database accesses. This is also typical in other scenarios like too many RPCs or cache accesses.</p>
+<h3 id="trace-depth">Trace depth</h3>
+<p>Trace depth is also related latency. Like the <a href="#too-many-child-spans">too many child spans</a> scenario, each span latency looks good, but the whole trace is slow.</p>
+<p><img src="deep-trace-1.png" alt=""></p>
+<p align="center">Trace depth</p>
+<p>Here, the slowest spans are less than 500ms, which are not too slow for a 2000ms trace. When you see the first line, there are four different colors representing four services involved in this distributed trace. Every one of them costs 100~400ms. For all four, there nearly 2000ms. From here, we know this slow trace is caused by 3 RPCs in a serial sequence.</p>
+<h2 id="at-the-end">At the end</h2>
+<p>Distributed tracing and APM tools help users identify root causes, allowing development and operation teams to optimize accordingly. We hope you enjoyed this, and love Apache SkyWalking and our new trace visualization. If so, <a href="https://github.com/apache/incubator-skywalking">give us a star on GitHub</a> to encourage us.</p>

+<p>Service mesh receiver was first introduced in Apache SkyWalking 6.0.0-beta. It is designed to provide a common entrance for receiving telemetry data from service mesh framework, for instance, Istio, Linkerd, Envoy etc. What’s the service mesh? According to Istio’s explain:</p>
+<p>The term service mesh is used to describe the network of microservices that make up such applications and the interactions between them.</p>
+<p>As a PMC member of Apache SkyWalking, I tested trace receiver and well understood the performance of collectors in trace scenario. I also would like to figure out the performance of service mesh receiver.</p>
+<h2 id="different-between-trace-and-service-mesh">Different between trace and service mesh</h2>
+<p>Following chart presents a typical trace map:</p>
+<p><img src="image5.png" alt=""></p>
+<p>You could find a variety of elements in it just like web service, local method, database, cache, MQ and so on. But service mesh only collect service network telemetry data that contains the entrance and exit data of a service for now(more elements will be imported soon, just like Database). A smaller quantity of data is sent to the service mesh receiver than the trace.</p>
+<p><img src="image1.png" alt=""></p>
+<p>But using sidecar is a little different.The client requesting “A” that will send a segment to service mesh receiver from “A”’s sidecar. If “A” depends on “B”, another segment will be sent from “A”’s sidecar. But for a trace system, only one segment is received by the collector. The sidecar model splits one segment into small segments, that will increase service mesh receiver network overhead.</p>
+<h2 id="deployment-architecture">Deployment Architecture</h2>
+<p>In this test, I will pick two different backend deployment. One is called mini unit, consist of one collector and one elasticsearch instance. Another is a standard production cluster, contains three collectors and three elasticsearch instances.</p>
+<p>Mini unit is a suitable architecture for dev or test environment. It saves your time and VM resources, speeds up depolyment process.</p>
+<p>The standard cluster provides good performance and HA for a production scenario. Though you will pay more money and take care of the cluster carefully, the reliability of the cluster will be a good reward to you.</p>
+<p>I pick 8 CPU and 16GB VM to set up the test environment. This test targets the performance of normal usage scenarios, so that choice is reasonable. The cluster is built on Google Kubernetes Engine(GKE), and every node links each other with a VPC network. For running collector is a CPU intensive task, the resource request of collector deployment should be 8 CPU, which means every collector instance occupy a VM node.</p>
+<h2 id="testing-process">Testing Process</h2>
+<p>Receiving mesh fragments per second(MPS) depends on the following variables.</p>
+<ol>
+<li>Ingress query per second(QPS)</li>
+<li>The topology of a microservice cluster</li>
+<li>Service mesh mode(proxy or sidecar)</li>
+</ol>
+<p>In this test, I use Bookinfo app as a demo cluster.</p>
+<p><img src="image6.png" alt=""></p>
+<p>So every request will touch max 4 nodes. Plus picking the sidecar mode(every request will send two telemetry data), the MPS will be QPS * 4 *2.</p>
+<p>There are also some important metrics that should be explained</p>
+<ul>
+<li>Client Query Latency: GraphQL API query response time heatmap.</li>
+<li>Client Mesh Sender: Send mesh segments per second. The total line represents total send amount and the error line is the total number of failed send.</li>
+<li>Mesh telemetry latency: service mesh receiver handling data heatmap.</li>
+<li>Mesh telemetry received: received mesh telemetry data per second.</li>
+</ul>
+<h3 id="mini-unit">Mini Unit</h3>
+<p><img src="image3.png" alt=""></p>
+<p>You could find collector can process up to <strong>25k</strong> data per second. The CPU usage is about 4 cores. Most of the query latency is less than 50ms. After login the VM on which collector instance running, I know that system load is reaching the limit(max is 8).</p>
+<p><img src="image2.png" alt=""></p>
+<p>According to the previous formula, a single collector instance could process <strong>3k</strong> QPS of Bookinfo traffic.</p>
+<h3 id="standard-cluster">Standard Cluster</h3>
+<p><img src="image4.png" alt=""></p>
+<p>Compare to the mini-unit, cluster’s throughput increases linearly. Three instances provide total 80k per second processing power. Query latency increases slightly, but it’s also very small(less than 500ms). I also checked every collector instance system load that all reached the limit. 10k QPS of BookInfo telemetry data could be processed by the cluster.</p>
+<h2 id="conclusion">Conclusion</h2>
+<p>Let’s wrap them up. There are some important things you could get from this test.</p>
+<ul>
+<li>QPS varies by the there variables. The test results in this blog are not important. The user should pick property value according to his system.</li>
+<li>Collector cluster’s processing power could scale out.</li>
+<li>The collector is CPU intensive application. So you should provide sufficient CPU resource to it.</li>
+</ul>
+<p>This blog gives people a common method to evaluate the throughput of Service Mesh Receiver. Users could use this to design their Apache Skywalking backend deployment architecture.</p>

+<p>The SkyWalking project provides distributed tracing, topology map analysis, service mesh telemetry analysis, metrics analysis and a super cool visualization
+targeting distributed systems in k8s or traditional VM deployments.</p>
+<p>The project is widely used in Alibaba, Huawei, Tencent, DiDi, xiaomi, Pingan, China’s top 3 telecom companies (China Mobile, China telecom, China Unicom), airlines, banks and more. It has over 140 company users listed on our <a href="https://github.com/apache/skywalking/blob/master/docs/powered-by.md">powered by</a> page.</p>
+<p>Today, we welcome and celebrate reaching 200 code contributors on our main repo. We hereby mark this milestone as official today, : <strong>Jan. 20th 2020</strong>.</p>
+<p>At this great moment, I would like to share SkyWalking’s 4-year open source journey.</p>
+<p>I wrote the first line on Nov. 1st, 2015, guiding people to understand a distributed system just as micro-services and distributed architecture were becoming popular.
+In the first 2 years, I never thought it would become such a big and active community. I didn’t even expect it would be an open source project.
+Initially, the goal was primarily to teach others about distributed tracing and analysis.</p>
+<p>It was a typical open source project in obscurity in its first two years. But
+people still showed up, asked questions, and tried to improve the project. I got several invitations to share the project at local meetups.All these made me realize people really needed a good open source APM project.</p>
+<p>In 2017, I decided to dedicate myself as much as possible to make the project successful, and it became my day job. To be honest, I had no clue about how to do that; at that time in China, it was rare to have this kind of job.
+So, I began to ask friends around me, “Do you want to collaborate on the open source APM with me?” Most people were busy and gave a clear <strong>NO</strong>, but two of them agreed to help: Xin Zhang and Yongsheng Peng. We built SkyWalking 3.x and shared the 3.2 release at GOPS Shanghai, China.</p>
+<p>It became the first adoption version used in production</p>
+<p>Compared to today’s SkyWalking, it was a toy prototype, but it had the same tracing design, protocol and analysis method.</p>
+<p>That year the contributor team was 15-20, and the project had obvious potential to expand. I began to consider bringing the project into a worldwide, top-level open source foundation. Thanks to our initial incubator mentors, Michael Semb Wever, William Jiang, and Luke Han, this really worked.
+At the end of 2017, SkyWalking joined the Apache Incubator, and kept following the Apache Way to build community. More contributors joined the community.</p>
+<p>With more people spending time on the project collaborations, including codes, tests, blogs, conference talks, books and uses of the project, a chemical reaction happens. New developers begin to provide bug fixes, new feature requirements and new proposals.
+At the moment of graduation in spring 2019, the project had 100 contributors. Now, only 9 months later, it’s surged to 200 super quickly. They enhance the project and extend it to frontiers we never imaged: 5 popular language agents, service mesh adoption, CLI tool, super cool visualization. We are even moving on thread profiling, browser performance and Nginx tracing NOW.</p>
+<p>Over the whole 4+ years open source journey, we have had supports from leaders in the tracing open source community around the world, including Adrian Cole, William Jiang, Luke Han, Michael Semb Wever, Ben Sigelman, and Jonah Kowall. And we’ve had critical foundations’ help, especially Apache Software Foundation and the Cloud Native Computing Foundation.</p>
+<p>Our contributors also have their support from their employers, including, to the best of my knowledge, Alibaba, Huawei, China Mobile, ke.com, DaoCloud, Lizhi.fm, Yonghui Supermarket, and dangdang.com. I also have support from my employers, <a href="https://www.tetrate.io/">tetrate.io</a>, Huawei, and OneAPM.</p>
+<p>Thanks to our 200+ contributors and the companies behind them. You make this magic happen.</p>

-<p>The SkyWalking project provides distributed tracing, topology map analysis, service mesh telemetry analysis, metrics analysis and a super cool visualization
-targeting distributed systems in k8s or traditional VM deployments.</p>
-<p>The project is widely used in Alibaba, Huawei, Tencent, DiDi, xiaomi, Pingan, China’s top 3 telecom companies (China Mobile, China telecom, China Unicom), airlines, banks and more. It has over 140 company users listed on our <a href="https://github.com/apache/skywalking/blob/master/docs/powered-by.md">powered by</a> page.</p>
-<p>Today, we welcome and celebrate reaching 200 code contributors on our main repo. We hereby mark this milestone as official today, : <strong>Jan. 20th 2020</strong>.</p>
-<p>At this great moment, I would like to share SkyWalking’s 4-year open source journey.</p>
-<p>I wrote the first line on Nov. 1st, 2015, guiding people to understand a distributed system just as micro-services and distributed architecture were becoming popular.
-In the first 2 years, I never thought it would become such a big and active community. I didn’t even expect it would be an open source project.
-Initially, the goal was primarily to teach others about distributed tracing and analysis.</p>
-<p>It was a typical open source project in obscurity in its first two years. But
-people still showed up, asked questions, and tried to improve the project. I got several invitations to share the project at local meetups.All these made me realize people really needed a good open source APM project.</p>
-<p>In 2017, I decided to dedicate myself as much as possible to make the project successful, and it became my day job. To be honest, I had no clue about how to do that; at that time in China, it was rare to have this kind of job.
-So, I began to ask friends around me, “Do you want to collaborate on the open source APM with me?” Most people were busy and gave a clear <strong>NO</strong>, but two of them agreed to help: Xin Zhang and Yongsheng Peng. We built SkyWalking 3.x and shared the 3.2 release at GOPS Shanghai, China.</p>
-<p>It became the first adoption version used in production</p>
-<p>Compared to today’s SkyWalking, it was a toy prototype, but it had the same tracing design, protocol and analysis method.</p>
-<p>That year the contributor team was 15-20, and the project had obvious potential to expand. I began to consider bringing the project into a worldwide, top-level open source foundation. Thanks to our initial incubator mentors, Michael Semb Wever, William Jiang, and Luke Han, this really worked.
-At the end of 2017, SkyWalking joined the Apache Incubator, and kept following the Apache Way to build community. More contributors joined the community.</p>
-<p>With more people spending time on the project collaborations, including codes, tests, blogs, conference talks, books and uses of the project, a chemical reaction happens. New developers begin to provide bug fixes, new feature requirements and new proposals.
-At the moment of graduation in spring 2019, the project had 100 contributors. Now, only 9 months later, it’s surged to 200 super quickly. They enhance the project and extend it to frontiers we never imaged: 5 popular language agents, service mesh adoption, CLI tool, super cool visualization. We are even moving on thread profiling, browser performance and Nginx tracing NOW.</p>
-<p>Over the whole 4+ years open source journey, we have had supports from leaders in the tracing open source community around the world, including Adrian Cole, William Jiang, Luke Han, Michael Semb Wever, Ben Sigelman, and Jonah Kowall. And we’ve had critical foundations’ help, especially Apache Software Foundation and the Cloud Native Computing Foundation.</p>
-<p>Our contributors also have their support from their employers, including, to the best of my knowledge, Alibaba, Huawei, China Mobile, ke.com, DaoCloud, Lizhi.fm, Yonghui Supermarket, and dangdang.com. I also have support from my employers, <a href="https://www.tetrate.io/">tetrate.io</a>, Huawei, and OneAPM.</p>
-<p>Thanks to our 200+ contributors and the companies behind them. You make this magic happen.</p>

+<p>Apache SkyWalking, the observability platform, and open-source application performance monitor (APM) project, today announced the general availability of its 8.1 release that extends its functionalities and provides a transport layer to maintain the lightweight of the platform that observes data continuously.</p>
+<h2 id="background">Background</h2>
+<p>SkyWalking is an observability platform and APM tool that works with or without a service mesh, providing automatic instrumentation for microservices, cloud-native and container-based applications. The top-level Apache project is supported by a global community and is used by Alibaba, Huawei, Tencent, Baidu, and scores of others.</p>
+<h2 id="transport-traces">Transport traces</h2>
+<p>For a long time, SkyWalking has used gRPC and HTTP to transport traces, metrics, and logs. They provide good performance and are quite lightweight, but people kept asking about the MQ as a transport layer because they want to keep the observability data continuously as much as possible. From SkyWalking’s perspective, the MQ based transport layer consumes more resources required in the deployment and the complexity of deployment and maintenance but brings more powerful throughput capac [...]
+<p>In 8.1.0, SkyWalking officially provides the typical MQ implementation, Kafka, to transport all observability data, including traces, metrics, logs, and profiling data. At the same time, the backend can support traditional gRPC and HTTP receivers, with the new Kafka consumer at the same time. Different users could choose the transport layer(s) according to their own requirements.

+<h2 id="notable-enhancements">Notable enhancements</h2>
+<p>The Java agent core is enhanced in this release. It could work better in the concurrency class loader case and is more compatible with another agent solution, such as Alibaba’s Arthas.</p>
+<ol>
+<li>With the logic endpoint supported, the local span can be analyzed to get metrics. One span could carry the raw data of more than one endpoint’s performance.</li>
+<li>GraphQL, InfluxDB Java Client, and Quasar fiber libs are supported to be observed automatically.</li>
+<li>Kubernetes Configmap can now for the first time be used as the dynamic configuration center– a more cloud-native solution for k8s deployment environments.</li>
+<li>OAP supports health checks, especially including the storage health status. If the storage (e.g., ElasticSearch) is not available, you could get the unhealth status with explicit reasons through the health status query.</li>
+<li>Opencensus receiver supports ingesting OpenTelemetry/OpenCensus agent metrics by meter-system.</li>

For applications using Micrometer with the SkyWalking agent installed, all Micrometer collected metrics could then be shipped into SkyWalking OAP. With <a href="https://github.com/apache/skywalking/blob/master/docs/en/setup/backend/spring-sleuth-se [...]

-<h2 id="notable-enhancements">Notable enhancements</h2>
-<p>The Java agent core is enhanced in this release. It could work better in the concurrency class loader case and is more compatible with another agent solution, such as Alibaba’s Arthas.</p>
-<ol>
-<li>With the logic endpoint supported, the local span can be analyzed to get metrics. One span could carry the raw data of more than one endpoint’s performance.</li>
-<li>GraphQL, InfluxDB Java Client, and Quasar fiber libs are supported to be observed automatically.</li>
-<li>Kubernetes Configmap can now for the first time be used as the dynamic configuration center– a more cloud-native solution for k8s deployment environments.</li>
-<li>OAP supports health checks, especially including the storage health status. If the storage (e.g., ElasticSearch) is not available, you could get the unhealth status with explicit reasons through the health status query.</li>
-<li>Opencensus receiver supports ingesting OpenTelemetry/OpenCensus agent metrics by meter-system.</li>

+<li>Oct. 29th, 2020</li>
+</ul>
+<p>Apache SkyWalking, the observability platform, and open-source application performance monitor (APM) project, today announced the general availability of its 8.2 release. The release extends Apache SkyWalking’s functionalities and monitoring boundary to the browser side.</p>
+<h2 id="background">Background</h2>
+<p>SkyWalking is an observability platform and APM tool that works with or without a service mesh, providing automatic instrumentation for microservices, cloud-native and container-based applications. The top-level Apache project is supported by a global community and is used by Alibaba, Huawei, Tencent, Baidu, ByteDance, and scores of others.</p>
+<h2 id="browser-side-monitoring">Browser side monitoring</h2>
+<p>APM helps SRE and Engineering teams to diagnose system failures, or optimize the systems before they become intolerably slow. But is it enough to always make the users happy?</p>
+<p>In 8.2.0, SkyWalking extends its monitoring boundary to the browser side, e.g., Chrome, or the network between Chrome and the backend service, or the codes running in the browser. With this, not only can we monitor the backend services and requests sent by the browser as usual, but also the front end rendering speed, error logs, etc., which are the most efficient metrics for capturing the experiences of our end users. (This does not currently extend to IoT devices, but this feature mo [...]
+<p><img src="0081Kckwly1gkl5m71k6bj30zk0m8tdb.jpg" alt="SkyWalking 8.2.0 Browser Side Monitoring: Overview"></p>
+<p>What’s more, SkyWalking browser monitoring also provides data about how the users use products, such as PV(page views), UV(unique visitors), top N PV(page views), etc., which can give a product team clues for optimizing their products.</p>
+<p><img src="0081Kckwly1gkl5m5tld9j30zk0m843n.jpg" alt="SkyWalking 8.2.0 Browser Side Monitoring: Pages"></p>
+<h2 id="query-traces-by-tags">Query traces by tags</h2>
+<p>In SkyWalking’s Span data model, there are many important fields that are already indexed and can be queried by the users, but for the sake of performance, querying by Span tags was not supported until now. In SkyWalking 8.2.0, we allow users to query traces by specified tags, which is extremely useful. For example, SRE engineers running tests on the product environment can tag the synthetic traffic and query by this tag later.</p>
+<h2 id="meter-analysis-language">Meter Analysis Language</h2>
+<p>In 8.2.0, the meter system provides a functional analysis language called MAL(Meter Analysis Language) that allows users to analyze and aggregate meter data in the OAP streaming system. The result of an expression can be ingested by either the agent analyzer or OpenTelemetry/Prometheus analyzer.</p>
+<h2 id="composite-alert-rules">Composite Alert Rules</h2>
+<p>Alerting is a good way to discover system failures in time. A common problem is that we configure too many triggers just to avoid missing any possible issue. Nobody likes to be woken up by alert messages at midnight, only to find out that the trigger is too sensitive. These kinds of alerts become noisy and don’t help at all.</p>
+<p>In 8.2.0, users can now configure composite alert rules, where composite rules take multiple metrics dimensions into account. With composite alert rules, we can leverage as many metrics as needed to more accurately determine whether there’s a real problem or just an occasional glitch.</p>
+<p>Common scenarios like <code>successful rate < 90% but there are only 1~2 requests</code> can now be resolved by a composite rule, such as <code>traffic(calls per minute) > n && successful rate < m%</code>.</p>
+<h2 id="other-notable-enhancements">Other Notable Enhancements</h2>

-<p>Apache SkyWalking, the observability platform, and open-source application performance monitor (APM) project, today announced the general availability of its 8.2 release. The release extends Apache SkyWalking’s functionalities and monitoring boundary to the browser side.</p>
-<h2 id="background">Background</h2>
-<p>SkyWalking is an observability platform and APM tool that works with or without a service mesh, providing automatic instrumentation for microservices, cloud-native and container-based applications. The top-level Apache project is supported by a global community and is used by Alibaba, Huawei, Tencent, Baidu, ByteDance, and scores of others.</p>
-<h2 id="browser-side-monitoring">Browser side monitoring</h2>
-<p>APM helps SRE and Engineering teams to diagnose system failures, or optimize the systems before they become intolerably slow. But is it enough to always make the users happy?</p>
-<p>In 8.2.0, SkyWalking extends its monitoring boundary to the browser side, e.g., Chrome, or the network between Chrome and the backend service, or the codes running in the browser. With this, not only can we monitor the backend services and requests sent by the browser as usual, but also the front end rendering speed, error logs, etc., which are the most efficient metrics for capturing the experiences of our end users. (This does not currently extend to IoT devices, but this feature mo [...]
-<p><img src="0081Kckwly1gkl5m71k6bj30zk0m8tdb.jpg" alt="SkyWalking 8.2.0 Browser Side Monitoring: Overview"></p>
-<p>What’s more, SkyWalking browser monitoring also provides data about how the users use products, such as PV(page views), UV(unique visitors), top N PV(page views), etc., which can give a product team clues for optimizing their products.</p>
-<p><img src="0081Kckwly1gkl5m5tld9j30zk0m843n.jpg" alt="SkyWalking 8.2.0 Browser Side Monitoring: Pages"></p>
-<h2 id="query-traces-by-tags">Query traces by tags</h2>
-<p>In SkyWalking’s Span data model, there are many important fields that are already indexed and can be queried by the users, but for the sake of performance, querying by Span tags was not supported until now. In SkyWalking 8.2.0, we allow users to query traces by specified tags, which is extremely useful. For example, SRE engineers running tests on the product environment can tag the synthetic traffic and query by this tag later.</p>
-<h2 id="meter-analysis-language">Meter Analysis Language</h2>
-<p>In 8.2.0, the meter system provides a functional analysis language called MAL(Meter Analysis Language) that allows users to analyze and aggregate meter data in the OAP streaming system. The result of an expression can be ingested by either the agent analyzer or OpenTelemetry/Prometheus analyzer.</p>
-<h2 id="composite-alert-rules">Composite Alert Rules</h2>
-<p>Alerting is a good way to discover system failures in time. A common problem is that we configure too many triggers just to avoid missing any possible issue. Nobody likes to be woken up by alert messages at midnight, only to find out that the trigger is too sensitive. These kinds of alerts become noisy and don’t help at all.</p>
-<p>In 8.2.0, users can now configure composite alert rules, where composite rules take multiple metrics dimensions into account. With composite alert rules, we can leverage as many metrics as needed to more accurately determine whether there’s a real problem or just an occasional glitch.</p>
-<p>Common scenarios like <code>successful rate < 90% but there are only 1~2 requests</code> can now be resolved by a composite rule, such as <code>traffic(calls per minute) > n && successful rate < m%</code>.</p>
-<h2 id="other-notable-enhancements">Other Notable Enhancements</h2>
-<ol>
-<li>The agent toolkit exposes some APIs for users to send customizable metrics.</li>
-<li>The agent <code>exclude_plugins</code> allows you to exclude some plugins; <code>mount</code> enables you to load a new set of plugins.</li>
-<li>More than 10 new plugins have been contributed to the agent.</li>
-<li>The alert system natively supports sending alert messages to Slack, WeChat, DingTalk.</li>

+ <p>Sheng Wu is a founding engineer at tetrate.io, leads the observability for service mesh and hybrid cloud. A searcher, evangelist, and developer in the observability, distributed tracing, and APM. He is a member of the Apache Software Foundation. Love open source software and culture. Created the Apache SkyWalking project and being its VP and PMC member. Co-founder and PMC member of Apache ShardingSphere. Also as a PMC member of Apache Incubator and APISIX. He is awarded as Microsoft [...]
+<p>In the Apache FY2020 report, China is on the top of the download statistics. More China initiated projects joined the incubator, and some of them graduated as the Apache TLP. Sheng joined the Apache community since 2017, in the past 3 years, he witnessed the growth of the open-source culture and Apache way in China.
+Many developers have joined the ASF as new contributors, committers, foundation members. Chinese enterprises and companies paid more attention to open source contributions, rather than simply using the project like before. In the keynote, he would share the progress about China embracing the Apache culture, and willing of enhancing the whole Apache community.</p>

+ <p>The APM system provides the tracing or metrics for distributed systems or microservice architectures. Back to APM themselves, they always need backend storage to store the necessary massive data. What are the features required for backend storage?

- <p>The APM system provides the tracing or metrics for distributed systems or microservice architectures. Back to APM themselves, they always need backend storage to store the necessary massive data. What are the features required for backend storage? Simple, fewer dependencies, widely used query language, and the efficiency could be into your consideration. Based on that, traditional SQL databases (like MySQL) or NoSQL databases would be better choices. However, this topic will present [...]
-<p>As a senior DBA worked at JD.com, the responsibility is to develop the distributed database and middleware, and the automated management platform for database clusters. As a PMC of Apache ShardingSphere, I am willing to contribute to the OS community and explore the area of distributed databases and NewSQL.</p>

- <p>Over the past few years, and coupled with the growing adoption of microservices, distributed tracing has emerged as one of the most commonly used monitoring and troubleshooting methodologies. New tracing tools are increasingly being introduced, driving adoption even further. One of these tools is Apache SkyWalking, a popular open-source tracing, and APM platform. This talk explores the history of the SkyWalking storage module, shows the evolution of distributed tracing storage layers [...]
-<p>Hongtao Gao is the engineer of tetrate.io and the former Huawei Cloud expert. One of PMC members of Apache SkyWalking and participates in some popular open-source projects such as Apache ShardingSphere and Elastic-Job. He has an in-depth understanding of distributed databases, container scheduling, microservices, ServicMesh, and other technologies.</p>
