-<p>Collector modules aims to aggregate data from multiple instances.</p>
-<div class="section">
-<h2>Features<a name="Features"></a></h2>
-<p>Default implementation only store data in memory but you can easily extend it to store data in MongoDB or whatever you want.</p>
-<p>Note: this is on our roadmap</p></div>
-<div class="section">
-<h2>For the impatient<a name="For_the_impatient"></a></h2>
-<p>Take a servlet container and deploy <tt>sirona-collector-[version].war</tt>. Collection is done on <tt>/collector</tt> endpoint and reporting view is accesible through <tt>/sirona</tt> endpoint.</p></div>
-<div class="section">
-<h2>Configuration<a name="Configuration"></a></h2>
-<p>Just use the collector <tt>DataStoreFactory</tt>: <tt>org.apache.sirona.store.CollectorDataStoreFactory</tt>.</p>
-<p>For instance your <tt>sirona.properties</tt> can look like:</p>
-
-<div>
-<pre class="prettyprint linenums">
-org.apache.sirona.store.DataStoreFactory = org.apache.sirona.store.CollectorDataStoreFactory
-</pre></div>
-<p>The <tt>GaugeDataStore</tt> can be configured through <tt>org.apache.sirona.collector.gauge.store-class</tt> property. By default it uses the in memory implementation but you can set your own one if you want.</p>
-<p>Note: if your <tt>GaugeDataStore</tt> has a constructor with a <tt>String</tt>, the marker of the store will be passed to the <tt>GaugeDataStore</tt>.</p>
-<p>The <tt>CounterDataStore</tt> needs to be an instance of <tt>org.apache.sirona.store.counter.CollectorCounterStore</tt>. By default it is in memory too but it is easily extensible to be persisted if needed.</p></div>
-<div class="section">
-<h2>Installing the collector<a name="Installing_the_collector"></a></h2>
-<p>To setup the collector you just need to configure the <tt>DataStoreFactory</tt> (see configuration part) and configure the servlet <tt>org.apache.sirona.collector.server.Collector</tt>.</p></div>
-<div class="section">
-<h2>Pushing data<a name="Pushing_data"></a></h2>
-<p>The input is an array of event. Events are either gauges or counters.</p>
-<p>Here is an array with a single gauge:</p>
-
-<div>
-<pre class="prettyprint linenums">
-[
-    {
-        &quot;type&quot;: &quot;gauge&quot;,
-        &quot;time&quot;: &quot;-&quot;,

+<p>Collector modules aims to aggregate data from multiple instances.</p>
+<div class="section">
+<h2>Features<a name="Features"></a></h2>
+<p>Default implementation only store data in memory but you can easily extend it to store data in MongoDB or whatever you want.</p>
+<p>Note: this is on our roadmap</p></div>
+<div class="section">
+<h2>For the impatient<a name="For_the_impatient"></a></h2>
+<p>Take a servlet container and deploy <tt>sirona-collector-[version].war</tt>. Collection is done on <tt>/collector</tt> endpoint and reporting view is accesible through <tt>/sirona</tt> endpoint.</p></div>
+<div class="section">
+<h2>Configuration<a name="Configuration"></a></h2>
+<p>Just use the collector <tt>DataStoreFactory</tt>: <tt>org.apache.sirona.store.CollectorDataStoreFactory</tt>.</p>
+<p>For instance your <tt>sirona.properties</tt> can look like:</p>
+
+<div>
+<pre class="prettyprint linenums">
+org.apache.sirona.store.DataStoreFactory = org.apache.sirona.store.CollectorDataStoreFactory
+</pre></div>
+<p>The <tt>GaugeDataStore</tt> can be configured through <tt>org.apache.sirona.collector.gauge.store-class</tt> property. By default it uses the in memory implementation but you can set your own one if you want.</p>
+<p>Note: if your <tt>GaugeDataStore</tt> has a constructor with a <tt>String</tt>, the marker of the store will be passed to the <tt>GaugeDataStore</tt>.</p>
+<p>The <tt>CounterDataStore</tt> needs to be an instance of <tt>org.apache.sirona.store.counter.CollectorCounterStore</tt>. By default it is in memory too but it is easily extensible to be persisted if needed.</p></div>
+<div class="section">
+<h2>Installing the collector<a name="Installing_the_collector"></a></h2>
+<p>To setup the collector you just need to configure the <tt>DataStoreFactory</tt> (see configuration part) and configure the servlet <tt>org.apache.sirona.collector.server.Collector</tt>.</p></div>
+<div class="section">
+<h2>Pushing data<a name="Pushing_data"></a></h2>
+<p>The input is an array of event. Events are either gauges or counters.</p>
+<p>Here is an array with a single gauge:</p>
+
+<div>
+<pre class="prettyprint linenums">
+[
+    {
+        &quot;type&quot;: &quot;gauge&quot;,
+        &quot;time&quot;: &quot;-&quot;,
+        &quot;data&quot;: {
+            &quot;unit&quot;: &quot;u&quot;,
+            &quot;marker&quot;: &quot;client1&quot;,
+            &quot;value&quot;: 0.0,
+            &quot;role&quot;: &quot;mock&quot;
+        }
+    }

+<p>And here is an array with a single counter:</p>
+
+<div>
+<pre class="prettyprint linenums">

+          with other successful ASF projects. While incubation status is not necessarily a reflection of the

-under the License. --><h1>Repository</h1>
-<p>The repository is a singleton for the JVM. It is the entry point to get access to counters and gauges.</p>
-
-<div>
-<pre class="prettyprint linenums">
-public interface Repository extends Iterable&lt;Counter&gt; {
-    Counter getCounter(Counter.Key key);
-    void clear();
-    StopWatch start(Counter counter);
-
-    Map&lt;Long, Double&gt; getGaugeValues(long start, long end, Role role);
-    void stopGauge(Role role);
-}
-</pre></div>
-<h1>Counter</h1>
-<p>A counter is a statistic and concurrency holder. It aggregates the information provided computing the average, min, max, sum of logs, &#x2026;.</p>
-
-<div>
-<pre class="prettyprint linenums">
-public interface Counter {
-    Key getKey();
-    void reset();
-
-    void add(double delta);
-
-    AtomicInteger currentConcurrency();
-    int getMaxConcurrency();
-
-    double getMax();
-    double getMin();
-    long getHits();
-    double getSum();
-    double getStandardDeviation();
-    double getVariance();
-    double getMean();
-    double getSecondMoment();
-}
-</pre></div>
-<h1>Gauge</h1>
-<p>A gauge is a way to get a measure. It is intended to get a history of a metric.</p>
-
-<div>
-<pre class="prettyprint linenums">
-public interface Gauge {
-    Role role();
-    double value();
-}
-</pre></div>
-<h1>StopWatch</h1>
-<p>A StopWatch is just a handler for a measure with a counter.</p>
-
-<div>
-<pre class="prettyprint linenums">
-public interface StopWatch {
-    long getElapsedTime();
-
-    StopWatch stop();
-}
-</pre></div>
-<h1>Node status</h1>
-<p>Node statuses can be reported using <tt>org.apache.sirona.status.Validation</tt>. <tt>Validation</tt> and <tt>ValidationFactory</tt> (just a list of validation) can be registered using <tt>SPI</tt> mecanism (<tt>META-INF/services/org.apache.sirona.status.Validation</tt> and <tt>META-INF/services/org.apache.sirona.status.ValidationFactory</tt> by default).</p>
-<p><tt>Validation</tt> API is the following one:</p>
-
-<div>
-<pre class="prettyprint linenums">
-public interface Validation {
-    ValidationResult validate();
-}
-</pre></div>
-<p>A <tt>ValidationResult</tt> is just a message, a validation name and a status. It is aggregated by node to compute the node status keeping the lowest of all statuses of validation results.</p>
-<h1>DataStore</h1>
-<p>Counters, Gauges and status are saved and queried (in memory by default) through a DataStore. it allows you to plug behind it any kind of persistence you would like. There are generally two kind of stores: local or remote.</p>
-<p>Here are the entry points if you want more details:</p>
-
-<ul>
-  
-<li><tt>org.apache.sirona.store.counter.CounterDataStore</tt></li>
-  
-<li><tt>org.apache.sirona.store.gauge.GaugeDataStore</tt></li>
-  
-<li><tt>org.apache.sirona.store.status.NodeStatusDataStore</tt></li>
-  
-<li><tt>org.apache.sirona.store.counter.CollectorCounterStore</tt></li>
-  
-<li><tt>org.apache.sirona.store.gauge.CollectorGaugeDataStore</tt></li>
-</ul>
-<h1>AlertListener</h1>
-<p>Most of <tt>NodeStatusDataStore</tt> are able to maintain an <tt>AlertListener</tt> list. This allows to be called when a <tt>NodeStatus</tt> is <tt>DEGRADED</tt> or <tt>KO</tt> - nothing when it is <tt>OK</tt>.</p>
-<p>It will typically be used to send a mail or trigger an alert using a custom system.</p>

+<p>The repository is a singleton for the JVM. It is the entry point to get access to counters and gauges.</p>
+
+<div>
+<pre class="prettyprint linenums">
+public interface Repository extends Iterable&lt;Counter&gt; {
+    Counter getCounter(Counter.Key key);
+    void clear();
+    StopWatch start(Counter counter);
+
+    Map&lt;Long, Double&gt; getGaugeValues(long start, long end, Role role);
+    void stopGauge(Role role);
+}
+</pre></div>
+<h1>Counter</h1>
+<p>A counter is a statistic and concurrency holder. It aggregates the information provided computing the average, min, max, sum of logs, &#x2026;.</p>
+
+<div>
+<pre class="prettyprint linenums">
+public interface Counter {
+    Key getKey();
+    void reset();
+
+    void add(double delta);
+
+    AtomicInteger currentConcurrency();
+    int getMaxConcurrency();
+
+    double getMax();
+    double getMin();
+    long getHits();
+    double getSum();
+    double getStandardDeviation();
+    double getVariance();
+    double getMean();
+    double getSecondMoment();
+}
+</pre></div>
+<h1>Gauge</h1>
+<p>A gauge is a way to get a measure. It is intended to get a history of a metric.</p>
+
+<div>
+<pre class="prettyprint linenums">
+public interface Gauge {
+    Role role();
+    double value();
+}
+</pre></div>
+<h1>StopWatch</h1>
+<p>A StopWatch is just a handler for a measure with a counter.</p>
+
+<div>
+<pre class="prettyprint linenums">
+public interface StopWatch {
+    long getElapsedTime();
+
+    StopWatch stop();
+}
+</pre></div>
+<h1>Node status</h1>
+<p>Node statuses can be reported using <tt>org.apache.sirona.status.Validation</tt>. <tt>Validation</tt> and <tt>ValidationFactory</tt> (just a list of validation) can be registered using <tt>SPI</tt> mecanism (<tt>META-INF/services/org.apache.sirona.status.Validation</tt> and <tt>META-INF/services/org.apache.sirona.status.ValidationFactory</tt> by default).</p>
+<p><tt>Validation</tt> API is the following one:</p>
+
+<div>
+<pre class="prettyprint linenums">
+public interface Validation {
+    ValidationResult validate();
+}
+</pre></div>
+<p>A <tt>ValidationResult</tt> is just a message, a validation name and a status. It is aggregated by node to compute the node status keeping the lowest of all statuses of validation results.</p>
+<h1>DataStore</h1>
+<p>Counters, Gauges and status are saved and queried (in memory by default) through a DataStore. it allows you to plug behind it any kind of persistence you would like. There are generally two kind of stores: local or remote.</p>
+<p>Here are the entry points if you want more details:</p>
+
+<ul>
+  
+<li><tt>org.apache.sirona.store.counter.CounterDataStore</tt></li>
+  
+<li><tt>org.apache.sirona.store.gauge.GaugeDataStore</tt></li>
+  
+<li><tt>org.apache.sirona.store.status.NodeStatusDataStore</tt></li>
+  
+<li><tt>org.apache.sirona.store.counter.CollectorCounterStore</tt></li>
+  
+<li><tt>org.apache.sirona.store.gauge.CollectorGaugeDataStore</tt></li>
+</ul>
+<h1>AlertListener</h1>
+<p>Most of <tt>NodeStatusDataStore</tt> are able to maintain an <tt>AlertListener</tt> list. This allows to be called when a <tt>NodeStatus</tt> is <tt>DEGRADED</tt> or <tt>KO</tt> - nothing when it is <tt>OK</tt>.</p>
+<p>It will typically be used to send a mail or trigger an alert using a custom system.</p>

+  <small>Apache Sirona is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by
+          the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates
+          that the infrastructure, communications, and decision making process have stabilized in a manner consistent
+          with other successful ASF projects. While incubation status is not necessarily a reflection of the
+          completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the
+          ASF.</small>
