+Cluster Metrics Extension
+=========================
+
+Introduction
+------------
+
+The member nodes of the cluster can collect system health metrics and publish that to other cluster nodes
+and to the registered subscribers on the system event bus with the help of Cluster Metrics Extension.
+
+Cluster metrics information is primarily used for load-balancing routers,
+and can also be used to implement advanced metrics-based node life cycles,
+such as "Node Let-it-crash" when CPU steal time becomes excessive.
+
+Cluster Metrics Extension is a separate akka module delivered in ``akka-cluster-metrics`` jar.
+
+To enable usage of the extension you need to add the following dependency to your project:
+::
+
+
+ com.typesafe.akka
+ akka-cluster-metrics_@binVersion@
+ @version@
+
+
+and add the following configuration stanza to your ``application.conf``
+::
+
+ akka.extensions = [ "akka.cluster.metrics.ClusterMetricsExtension" ]
+
+Make sure to disable legacy metrics in akka-cluster: ``akka.cluster.metrics.enabled=off``,
+since it is still enabled in akka-cluster by default (for compatibility with past releases).
+
+Metrics Collector
+-----------------
+
+Metrics collection is delegated to an implementation of ``akka.cluster.metrics.MetricsCollector``.
+
+Different collector implementations provide different subsets of metrics published to the cluster.
+Certain message routing and let-it-crash functions may not work when Sigar is not provisioned.
+
+Cluster metrics extension comes with two built-in collector implementations:
+
+#. ``akka.cluster.metrics.SigarMetricsCollector``, which requires Sigar provisioning, and is more rich/precise
+#. ``akka.cluster.metrics.JmxMetricsCollector``, which is used as fall back, and is less rich/precise
+
+You can also plug-in your own metrics collector implementation.
+
+By default, metrics extension will use collector provider fall back and will try to load them in this order:
+
+#. configured user-provided collector
+#. built-in ``akka.cluster.metrics.SigarMetricsCollector``
+#. and finally ``akka.cluster.metrics.JmxMetricsCollector``
+
+Metrics Events
+--------------
+
+Metrics extension periodically publishes current snapshot of the cluster metrics to the node system event bus.
+
+The publication period is controlled by the ``akka.cluster.metrics.collector.sample-period`` setting.
+
+The payload of the ``akka.cluster.metris.ClusterMetricsChanged`` event will contain
+latest metrics of the node as well as other cluster member nodes metrics gossip
+which was received during the collector sample period.
+
+You can subscribe your metrics listener actors to these events in order to implement custom node lifecycle
+::
+
+ ClusterMetricsExtension.get(system).subscribe(metricsListenerActor);
+
+Hyperic Sigar Provisioning
+--------------------------
+
+Both user-provided and built-in metrics collectors can optionally use `Hyperic Sigar `_
+for a wider and more accurate range of metrics compared to what can be retrieved from ordinary JMX MBeans.
+
+Sigar is using a native o/s library, and requires library provisioning, i.e.
+deployment, extraction and loading of the o/s native library into JVM at runtime.
+
+User can provision Sigar classes and native library in one of the following ways:
+
+#. Use `Kamon sigar-loader `_ as a project dependency for the user project.
+ Metrics extension will extract and load sigar library on demand with help of Kamon sigar provisioner.
+#. Use `Kamon sigar-loader `_ as java agent: ``java -javaagent:/path/to/sigar-loader.jar``.
+ Kamon sigar loader agent will extract and load sigar library during JVM start.
+#. Place ``sigar.jar`` on the ``classpath`` and Sigar native library for the o/s on the ``java.library.path``.
+ User is required to manage both project dependency and library deployment manually.
+
+To enable usage of Sigar you can add the following dependency to the user project
+::
+
+
+ io.kamon
+ sigar-loader
+ @sigarLoaderVersion@
+
+
+You can download Kamon sigar-loader from `Maven Central `_
+
+Adaptive Load Balancing
+-----------------------
+
+The ``AdaptiveLoadBalancingPool`` / ``AdaptiveLoadBalancingGroup`` performs load balancing of messages to cluster nodes based on the cluster metrics data.
+It uses random selection of routees with probabilities derived from the remaining capacity of the corresponding node.
+It can be configured to use a specific MetricsSelector to produce the probabilities, a.k.a. weights:
+
+* ``heap`` / ``HeapMetricsSelector`` - Used and max JVM heap memory. Weights based on remaining heap capacity; (max - used) / max
+* ``load`` / ``SystemLoadAverageMetricsSelector`` - System load average for the past 1 minute, corresponding value can be found in ``top`` of Linux systems. The system is possibly nearing a bottleneck if the system load average is nearing number of cpus/cores. Weights based on remaining load capacity; 1 - (load / processors)
+* ``cpu`` / ``CpuMetricsSelector`` - CPU utilization in percentage, sum of User + Sys + Nice + Wait. Weights based on remaining cpu capacity; 1 - utilization
+* ``mix`` / ``MixMetricsSelector`` - Combines heap, cpu and load. Weights based on mean of remaining capacity of the combined selectors.
+* Any custom implementation of ``akka.cluster.metrics.MetricsSelector``
+
+The collected metrics values are smoothed with `exponential weighted moving average `_. In the :ref:`cluster_configuration_java` you can adjust how quickly past data is decayed compared to new data.
+
+Let's take a look at this router in action. What can be more demanding than calculating factorials?
+
+The backend worker that performs the factorial calculation:
+
+.. includecode:: ../../../akka-samples/akka-sample-cluster-java/src/main/java/sample/cluster/factorial/FactorialBackend.java#backend
+
+The frontend that receives user jobs and delegates to the backends via the router:
+
+.. includecode:: ../../../akka-samples/akka-sample-cluster-java/src/main/java/sample/cluster/factorial/FactorialFrontend.java#frontend
+
+
+As you can see, the router is defined in the same way as other routers, and in this case it is configured as follows:
+
+.. includecode:: ../../../akka-samples/akka-sample-cluster-java/src/main/resources/factorial.conf#adaptive-router
+
+It is only ``router`` type and the ``metrics-selector`` parameter that is specific to this router,
+other things work in the same way as other routers.
+
+The same type of router could also have been defined in code:
+
+.. includecode:: ../../../akka-samples/akka-sample-cluster-java/src/main/java/sample/cluster/factorial/Extra.java#router-lookup-in-code
+

+
+The `Typesafe Activator `_ tutorial named
+`Akka Cluster Samples with Java `_.
+contains the full source code and instructions of how to run the **Adaptive Load Balancing** sample.
+
+Subscribe to Metrics Events
+---------------------------
+
+It is possible to subscribe to the metrics events directly to implement other functionality.
+
+.. includecode:: ../../../akka-samples/akka-sample-cluster-java/src/main/java/sample/cluster/factorial/MetricsListener.java#metrics-listener

+Custom Metrics Collector
+------------------------

+
+You can plug-in your own metrics collector instead of built-in
+``akka.cluster.metrics.SigarMetricsCollector`` or ``akka.cluster.metrics.JmxMetricsCollector``.
+
+Look at those two implementations for inspiration.
+
+Custom metrics collector implementation class must be specified in the :ref:`cluster_metrics_configuration_java`.

+New Cluster Metrics Extension
+=============================
+Previously, cluster metrics functionality was located in the ``akka-cluster`` jar.
+Now it is split out and moved into a separate akka module: ``akka-cluster-metrics`` jar.
+The module comes with few enhancements, such as use of Kamon sigar-loader
+for native library provisioning as well as use of statistical averaging of metrics data.
+Note that both old and new metrics configuration entries in the ``reference.conf``
+are still in the same name space ``akka.cluster.metrics`` but are not compatible.
+Make sure to disable legacy metrics in akka-cluster: ``akka.cluster.metrics.enabled=off``,
+since it is still enabled in akka-cluster by default (for compatibility with past releases).
+Router configuration entries have also changed for the module, they use prefix ``cluster-metrics-``:
+``cluster-metrics-adaptive-pool`` and ``cluster-metrics-adaptive-group``
+Metrics extension classes and objects are located in the new package ``akka.cluster.metrics``.
+Please see :ref:`Scala `, :ref:`Java ` for more information.

-.. includecode:: ../../../akka-samples/akka-sample-cluster-scala/src/main/resources/factorial.conf#adaptive-router
-
-It is only router type ``adaptive`` and the ``metrics-selector`` that is specific to this router, other things work
-in the same way as other routers.
-
-The same type of router could also have been defined in code:
-
-.. includecode:: ../../../akka-samples/akka-sample-cluster-scala/src/main/scala/sample/cluster/factorial/Extra.scala#router-lookup-in-code
-
-.. includecode:: ../../../akka-samples/akka-sample-cluster-scala/src/main/scala/sample/cluster/factorial/Extra.scala#router-deploy-in-code
-
-The `Typesafe Activator `_ tutorial named
-`Akka Cluster Samples with Scala `_.
-contains the full source code and instructions of how to run the **Adaptive Load Balancing** sample.
-
-Subscribe to Metrics Events
----------------------------
-
-It is possible to subscribe to the metrics events directly to implement other functionality.
-
-.. includecode:: ../../../akka-samples/akka-sample-cluster-scala/src/main/scala/sample/cluster/factorial/MetricsListener.scala#metrics-listener
-
-Custom Metrics Collector
-------------------------
-
-You can plug-in your own metrics collector instead of
-``akka.cluster.SigarMetricsCollector`` or ``akka.cluster.JmxMetricsCollector``. Look at those two implementations
-for inspiration. The implementation class can be defined in the :ref:`cluster_configuration_scala`.
