+<li><input checked="" disabled="" type="checkbox"> SkyWalking CLI: Using the CLI to report events from the command line interface.</li>

+</ul>
+<h2 id="event-definitions">Event Definitions</h2>
+<p>An event contains the following fields. The definitions of event can be found at the <a href="https://github.com/apache/skywalking-data-collect-protocol/tree/master/event">protocol repo</a>.</p>
+<h3 id="uuid">UUID</h3>
+<p>Unique ID of the event. Since an event may span a long period of time, the UUID is necessary to associate the start time with the end time of the same event.</p>
+<h3 id="source">Source</h3>
+<p>The source object on which the event occurs. In SkyWalking, the object is typically a service, service instance, etc.</p>
+<h3 id="name">Name</h3>
+<p>Name of the event. For example, <code>Start</code>, <code>Stop</code>, <code>Crash</code>, <code>Reboot</code>, <code>Upgrade</code>, etc.</p>
+<h3 id="type">Type</h3>
+<p>Type of the event. This field is friendly for UI visualization, where events of type <code>Normal</code> are considered normal operations,
+while <code>Error</code> is considered unexpected operations, such as <code>Crash</code> events. Marking them with different colors allows us to more easily identify them.</p>
+<h3 id="message">Message</h3>
+<p>The detail of the event that describes why this event happened. This should be a one-line message that briefly describes why the event is reported. Examples of an <code>Upgrade</code> event may be something like <code>Upgrade from ${from_version} to ${to_version}</code>.
+It’s NOT recommended to include the detailed logs of this event, such as the exception stack trace.</p>
+<h3 id="parameters">Parameters</h3>
+<p>The parameters in the <code>message</code> field. This is a simple <code><string,string></code> map.</p>
+<h3 id="start-time">Start Time</h3>
+<p>The start time of the event. This field is mandatory when an event occurs.</p>
+<h3 id="end-time">End Time</h3>
+<p>The end time of the event. This field may be empty if the event has not ended yet, otherwise there should be a valid timestamp after <code>startTime</code>.</p>
+<p><strong>NOTE:</strong> When reporting an event, you typically call the report function twice, the first time for starting of the event and the second time for ending of the event, both with the same UUID.
+There are also cases where you would already have both the start time and end time. For example, when exporting events from a third-party system, the start time and end time are already known so you may simply call the report function once.</p>

+<p>In SkyWalking, probe means an agent or SDK library integrated into a target system that takes charge of

+<p>On a high level, there are three typical categories in all SkyWalking probes.</p>
+<ul>
+<li>
+<p><strong>Language based native agent</strong>. These agents run in target service user spaces, such as a part of user codes. For example,
+the SkyWalking Java agent uses the <code>-javaagent</code> command line argument to manipulate codes in runtime, where <code>manipulate</code> means to change and inject
+user’s codes. Another kind of agents uses certain hook or intercept mechanism provided by target libraries. As you can see, these agents are based on languages and libraries.</p>
+</li>
+<li>
+<p><strong>Service Mesh probes</strong>. Service Mesh probes collect data from sidecar, control panel in service mesh or proxy. In the old days, proxy
+is only used as an ingress of the whole cluster, but with the Service Mesh and sidecar, we can now perform observability functions.</p>
+</li>
+<li>
+<p><strong>3rd-party instrument library</strong>. SkyWalking accepts many widely used instrument libraries data formats. It analyzes the
+data, transfers it to SkyWalking’s formats of trace, metrics or both. This feature starts with accepting Zipkin span data. See
+<a href="../../setup/backend/backend-receivers">Receiver for other tracers</a> for more information.</p>
+</li>
+</ul>
+<p>You don’t need to use <strong>Language based native agent</strong> and <strong>Service Mesh probe</strong> at the same time, since they both serve to collect
+metrics data. Otherwise, your system will suffer twice the payload, and the analytic numbers will be doubled.</p>
+<p>There are several recommended ways on how to use these probes:</p>
+<ol>
+<li>Use <strong>Language based native agent</strong> only.</li>
+<li>Use <strong>3rd-party instrument library</strong> only, like the Zipkin instrument ecosystem.</li>
+<li>Use <strong>Service Mesh probe</strong> only.</li>

+</ol>
+<p>What is the meaning of <strong>in tracing status</strong>?</p>
+<p>By default, <strong>Language based native agent</strong> and <strong>3rd-party instrument library</strong> both send distributed traces to the backend,
+where analyses and aggregation on those traces are performed. <strong>In tracing status</strong> means that the backend considers these traces as something

+<li>
+<p><strong>Maintaining Observability</strong>. Regardless of the deployment method of the target system, SkyWalking provides an integration solution for it to maintain observability. Based on this, SkyWalking provides multiple runtime forms and probes.</p>

+<li>
+<p><strong>Topology, Metrics and Trace Together</strong>. The first step to understanding a distributed system is the topology map. It visualizes the entire complex system in an easy-to-read layout. Under the topology, the OSS personnel have higher requirements in terms of the metrics for service, instance, endpoint and calls. Traces are in the form of detailed logs to make sense of those metrics.
+For example, when the endpoint latency becomes long, you want to see the slowest the trace to find out why. So you can see,
+they are from big picture to details, they are all needed. SkyWalking integrates and provides a lot of features to
+make this possible and easy understand.</p>

-<p>This document outlines the core design goals for the SkyWalking project.</p>
-<ul>
-<li>
-<p><strong>Maintaining Observability</strong>. Regardless of the deployment method of the target system, SkyWalking provides an integration solution for it to maintain observability. Based on this, SkyWalking provides multiple runtime forms and probes.</p>
-</li>
-<li>
-<p><strong>Topology, Metrics and Trace Together</strong>. The first step to understanding a distributed system is the topology map. It visualizes the entire complex system in an easy-to-read layout. Under the topology, the OSS personnel have higher requirements in terms of the metrics for service, instance, endpoint and calls. Traces are in the form of detailed logs to make sense of those metrics.
-For example, when the endpoint latency becomes long, you want to see the slowest the trace to find out why. So you can see,
-they are from big picture to details, they are all needed. SkyWalking integrates and provides a lot of features to
-make this possible and easy understand.</p>
-</li>
-<li>
-<p><strong>Light Weight</strong>. There two parts of light weight are needed. (1) In probe, we just depend on network
-communication framework, prefer gRPC. By that, the probe should be as small as possible, to avoid the library
-conflicts and the payload of VM, such as permsize requirement in JVM.

+<p>The service auto instrument agent is a subset of language-based native agents. This kind of agents is based on
+some language-specific features, especially those of a VM-based language.</p>
+<h2 id="what-does-auto-instrument-mean">What does Auto Instrument mean?</h2>
+<p>Many users learned about these agents when they first heard that “Not a single line of code has to be changed”. SkyWalking used to mention this in its readme page as well.
+However, this does not reflect the full picture. For end users, it is true that they no longer have to modify their codes in most cases.
+But it is important to understand that the codes are in fact still modified by the agent, which is usually known as “runtime code manipulation”. The underlying logic is that the
+auto instrument agent uses the VM interface for code modification to dynamically add in the instrument code, such as modifying the class in Java through
+<code>javaagent premain</code>.</p>
+<p>In fact, although the SkyWalking team has mentioned that most auto instrument agents are VM-based, you may build such tools during compiling time rather than
+runtime.</p>
+<h2 id="what-are-the-limitations">What are the limitations?</h2>
+<p>Auto instrument is very helpful, as you may perform auto instrument during compiling time, without having to depend on VM features. But there are also certain limitations that come with it:</p>
+<ul>
+<li>
+<p><strong>Higher possibility of in-process propagation in many cases</strong>. Many high-level languages, such as Java and .NET, are used for building business systems.
+Most business logic codes run in the same thread for each request, which causes propagation to be based on thread ID, in order for the stack module to make sure that the context is safe.</p>
+</li>
+<li>
+<p><strong>Only works in certain frameworks or libraries</strong>. Since the agents are responsible for modifying the codes during runtime, the codes are already known
+to the agent plugin developers. There is usually a list of frameworks or libraries supported by this kind of probes.
+For example, see the <a href="../../setup/service-agent/java-agent/supported-list">SkyWalking Java agent supported list</a>.</p>
+</li>
+<li>
+<p><strong>Cross-thread operations are not always supported</strong>. Like what is mentioned above regarding in-process propagation, most codes (especially business codes)
+run in a single thread per request. But in some other cases, they operate across different threads, such as assigning tasks to other threads, task pools or batch processes. Some languages may even provide coroutine or similar components like <code>Goroutine</code>, which allows developers to run async process with low payload. In such cases, auto instrument will face problems.</p>
+</li>
+</ul>
+<p>So, there’s nothing mysterious about auto instrument. In short, agent developers write an activation script to make

- <h1 id="service-auto-instrument-agent">Service Auto Instrument Agent</h1>
-<p>The service auto instrument agent is a subset of language-based native agents. This kind of agents is based on
-some language-specific features, especially those of a VM-based language.</p>
-<h2 id="what-does-auto-instrument-mean">What does Auto Instrument mean?</h2>
-<p>Many users learned about these agents when they first heard that “Not a single line of code has to be changed”. SkyWalking used to mention this in its readme page as well.
-However, this does not reflect the full picture. For end users, it is true that they no longer have to modify their codes in most cases.
-But it is important to understand that the codes are in fact still modified by the agent, which is usually known as “runtime code manipulation”. The underlying logic is that the
-auto instrument agent uses the VM interface for code modification to dynamically add in the instrument code, such as modifying the class in Java through
-<code>javaagent premain</code>.</p>
-<p>In fact, although the SkyWalking team has mentioned that most auto instrument agents are VM-based, you may build such tools during compiling time rather than
-runtime.</p>
-<h2 id="what-are-the-limitations">What are the limitations?</h2>
-<p>Auto instrument is very helpful, as you may perform auto instrument during compiling time, without having to depend on VM features. But there are also certain limitations that come with it:</p>
-<ul>
-<li>
-<p><strong>Higher possibility of in-process propagation in many cases</strong>. Many high-level languages, such as Java and .NET, are used for building business systems.
-Most business logic codes run in the same thread for each request, which causes propagation to be based on thread ID, in order for the stack module to make sure that the context is safe.</p>
-</li>
-<li>
-<p><strong>Only works in certain frameworks or libraries</strong>. Since the agents are responsible for modifying the codes during runtime, the codes are already known
-to the agent plugin developers. There is usually a list of frameworks or libraries supported by this kind of probes.
-For example, see the <a href="../../setup/service-agent/java-agent/supported-list">SkyWalking Java agent supported list</a>.</p>
-</li>
-<li>
-<p><strong>Cross-thread operations are not always supported</strong>. Like what is mentioned above regarding in-process propagation, most codes (especially business codes)
-run in a single thread per request. But in some other cases, they operate across different threads, such as assigning tasks to other threads, task pools or batch processes. Some languages may even provide coroutine or similar components like <code>Goroutine</code>, which allows developers to run async process with low payload. In such cases, auto instrument will face problems.</p>
-</li>
-</ul>
-<p>So, there’s nothing mysterious about auto instrument. In short, agent developers write an activation script to make
-instrument codes work for you. That’s it!</p>

+<h3 id="problem">Problem</h3>

+<li>
+<p>When using the SkyWalking agent, some other agents, such as Arthas, can’t work properly.
+<a href="https://github.com/apache/skywalking/pull/4858">https://github.com/apache/skywalking/pull/4858</a></p>

+<p>The retransform classes in the Java agent conflict with the SkyWalking agent, as illustrated in this <a href="https://github.com/SkyAPMTest/retransform-conflict-demo">demo</a></p>
+</li>
+</ol>
+<h3 id="cause">Cause</h3>
+<p>The SkyWalking agent uses ByteBuddy to transform classes when the Java application starts.
+ByteBuddy generates auxiliary classes with different random names every time.</p>
+<p>When another Java agent retransforms the same class, it triggers the SkyWalking agent to enhance the class again.
+Since the bytecode has been regenerated by ByteBuddy, the fields and imported class names have been modified, and the JVM verifications on class bytecode have failed, the retransform classes would therefore be unsuccessful.</p>
+<h3 id="resolution">Resolution</h3>
+<p><strong>1. Enable the class cache feature</strong></p>
+<p>Add JVM parameters:<br>
+<code>-Dskywalking.agent.is_cache_enhanced_class=true -Dskywalking.agent.class_cache_mode=MEMORY</code></p>
+<p>Or uncomment the following options in <code>agent.conf</code>:</p>
+<pre><code># If true, the SkyWalking agent will cache all instrumented classes files to memory or disk files (as determined by the class cache mode),
+# Allow other Java agents to enhance those classes that are enhanced by the SkyWalking agent.
+agent.is_cache_enhanced_class = ${SW_AGENT_CACHE_CLASS:false}
+
+# The instrumented classes cache mode: MEMORY or FILE
+# MEMORY: cache class bytes to memory; if there are too many instrumented classes or if their sizes are too large, it may take up more memory
+# FILE: cache class bytes to user temp folder starts with 'class-cache', and automatically clean up cached class files when the application exits
+agent.class_cache_mode = ${SW_AGENT_CLASS_CACHE_MODE:MEMORY}
+
+</code></pre><p>If the class cache feature is enabled, save the instrumented class bytecode to memory or a temporary file.
+When other Java agents retransform the same class, the SkyWalking agent first attempts to load from the cache.</p>
+<p>If the cached class is found, it will be used directly without regenerating an auxiliary class with a new random name.
+Then, the process of the subsequent Java agent will not be affected.</p>
+<p><strong>2. Class cache save mode</strong><br>
+We recommend saving cache classes to memory, if it takes up more memory space. Alternatively, you can use the local file system. Set the class cache mode in one of the folliwng ways:<br>
+<code>-Dskywalking.agent.class_cache_mode=MEMORY</code> : save cache classes to Java memory. <br>
+<code>-Dskywalking.agent.class_cache_mode=FILE</code> : save cache classes to SkyWalking agent path ‘/class-cache’.</p>

+<p>Like all applications, you may upgrade SkyWalking using the <code>canary release</code> method through the following steps.</p>
+<ol>
+<li>Deploy a new cluster by using the latest version of SkyWalking OAP cluster with the new database cluster.</li>
+<li>Once the target service (i.e. the service being monitored) has upgraded the agent.jar (or simply by rebooting), have <code>collector.backend_service</code>
+pointing to the new OAP backend, and use/add a new namespace(<code>agent.namespace</code> in <a href="../../setup/service-agent/java-agent/readme#table-of-agent-configuration-properties">Table of Agent Configuration Properties</a>).
+The namespace will prevent conflicts from arising between different versions.</li>
+<li>When all target services have been rebooted, the old OAP clusters could be discarded.</li>
+</ol>
+<p>The <code>Canary Release</code> method works for any version upgrades.</p>
+<h2 id="online-hot-reboot-upgrade">Online Hot Reboot Upgrade</h2>
+<p>The reason we require <code>Canary Release</code> is that the SkyWalking agent has cache mechanisms, and switching to a new cluster causes the
+cache to become unavailable for new OAP clusters.
+In version 6.5.0+ (especially for agent versions), we have <a href="../../setup/backend/backend-setup#agent-hot-reboot-trigger-mechanism-in-oap-server-upgrade"><strong>Agent hot reboot trigger mechanism</strong></a>.
+This streamlines the upgrade process as we <strong>deploy a new cluster by using the latest version of SkyWalking OAP cluster with the new database cluster</strong>,
+and shift the traffic to the new cluster once and for all. Based on the mechanism, all agents will enter the <code>cool_down</code> mode, and come
+back online. For more details, see the backend setup documentation.</p>
+<p><strong>NOTE</strong>: A known bug in 6.4.0 is that its agent may have re-connection issues; therefore, even though this bot reboot mechanism has been included in 6.4.0, it may not work under some network scenarios, especially in Kubernetes.</p>
+<h2 id="agent-compatibility">Agent Compatibility</h2>
+<p>All versions of SkyWalking 6.x (and even 7.x) are compatible with each other, so users could simply upgrade the OAP servers.

+<li>Say it is higher by 40% or more, such as by 70% to 200%. Then, it is likely that your MQ would use up more resources than it saves.
+Your MQ would support 2 to 3 times the payload using 10%-20% of the cost during usual times. Furthermore, in this case,
