org.cougaar.core.qos.profile
Utility components to periodically log performance metrics, such as the cpu load and message traffic.

The simplest configuration option is to profile the aggregate "messages per second" throughput. Add the following components to all nodes: 

  <!-- required profiler-management component -->
  <component
      class='org.cougaar.core.qos.profile.ProfilerCoordinator'
      priority='HIGH'
      insertionpoint='Node.AgentManager.Agent.Component'>
    <!-- optional period between logs, defaults to 60000 millis -->
    <argument>period=10000</argument>
  </component>

      <!-- message transport sensor -->
      <component
          class='org.cougaar.mts.std.StatisticsAspect'
          insertionpoint='Node.AgentManager.Agent.MessageTransport.Aspect'/>

  <!-- messaging throughput profiler -->
  <component
      class='org.cougaar.core.qos.profile.Throughput'/>
Example output: 
2005-04-29 13:23:39,297 SHOUT [throughput] - NodeA: #agent_send_count_per_second, total_send_count_per_second, agent_send_count, total_send_count,
2005-04-29 13:23:39,362 SHOUT [throughput] - NodeA: 0.00, 0.00, 0, 3
2005-04-29 13:23:49,103 SHOUT [throughput] - NodeA: 0.56, 1.78, 5, 19
2005-04-29 13:23:59,101 SHOUT [throughput] - NodeA: 27.22, 27.22, 250, 264
2005-04-29 13:24:09,102 SHOUT [throughput] - NodeA: 121.50, 121.50, 1465, 1479
2005-04-29 13:24:19,101 SHOUT [throughput] - NodeA: 160.89, 161.11, 2913, 2929
In the above example, the agents on NodeA are sending an aggregate 161 messages/second. This output is from a two-node "ping" test from AgentA on NodeA to a remote AgentB on NodeB.

For more detailed profiling, add the following components to all nodes: 

  <!-- required profiler-management component -->
  <component
      class='org.cougaar.core.qos.profile.ProfilerCoordinator'
      priority='HIGH'
      insertionpoint='Node.AgentManager.Agent.Component'/>

  <!-- mts components -->
      <component
          class='org.cougaar.mts.std.StatisticsAspect'
          insertionpoint='Node.AgentManager.Agent.MessageTransport.Aspect'/>
      <component
          class='org.cougaar.core.qos.tmatrix.AgentFlowAspect'
          insertionpoint='Node.AgentManager.Agent.MessageTransport.Aspect'/>

  <!-- optional mts-internal profilers (select none, any, or all) -->
  <component
      class='org.cougaar.core.qos.profile.LocalTraffic'
      insertionpoint='Node.AgentManager.Agent.MessageTransport.Component'/>
  <component
      class='org.cougaar.core.qos.profile.RemoteTraffic'

  <component
      class='org.cougaar.core.qos.profile.TrafficMatrix'
      insertionpoint='Node.AgentManager.Agent.MessageTransport.Component'/>

  <!-- metrics components and plugins -->

          class='org.cougaar.core.qos.rss.AgentHostUpdaterComponent'
          insertionpoint='Node.AgentManager.Agent.MetricsServices.Component'/>

      <component

  <!-- optional, required if above BlackboardSize is loaded -->
  <component
      class='org.cougaar.core.qos.profile.BlackboardSizeInAgent'/>
Plus add the following components to all agents: 
  <!-- optional, required if above PersistSize is loaded -->

      class='org.cougaar.core.qos.metrics.PersistenceAdapterPlugin'/>

  <!-- optional, required if above BlackboardSize is loaded -->

Java Source File NameTypeComment
BlackboardSize.javaClass This component profiles the per-agent blackboard size and add/change/remove counts for standard blackboard object types (UniqueObject, Task, etc).

Example output:

 
 bb_AgentA__Task - #current, added, changed, removed
 bb_AgentA__Task - 5807, 7615, 3514, 1806
 bb_AgentA__UniqueObject - 11853, 18841, 46569, 6988
 bb_AgentA__transactions - 192, 192, 0, 0
In this example, 5807 tasks are on the blackboard.
BlackboardSizeInAgent.javaClass This component supports the node-level BlackboardSize profiler.
BlackboardSizeService.javaInterface This service registers agents with the node-level BlackboardSize profiler.
JavaHeapSize.javaClass This component profiles the JVM heap size (used, free, total, max).

Example output:

 jvmheap - #used_bytes, free_bytes, total_bytes, max_bytes
 jvmheap - 5430096, 5084336, 10514432, 66650112
In this example, the current JVM heap size is 5.18 mb.

LocalTraffic.javaClass This component profiles the message traffic (message count and byte count) of each local agents to any target.

I.e.

NodeTraffic.javaClass This component profiles the aggregate message traffic of all local agents to any target.
PersistSize.javaClass This component profiles persistence activity for each agent and the aggegate node "sum".
ProcLoadAvg.javaClass This component profiles the CPU load from "/proc/loadavg".

ProcStat.javaClass This component profiles system activity from "/proc/stat".
ProcStatus.javaClass This component profiles the JVM's process size from "/proc/self/status" (VmSize & VmRSS).
ProfilerBase.javaClass This component is the common base class for profiler components.
ProfilerCoordinator.javaClass This component coordinates the profiler components to log at the same time.
ProfilerService.javaInterface
RemoteTraffic.javaClass This component profiles the message traffic (message count and byte count) from the local aggregated agents to each specific remote target agent.

I.e.

Resources.javaClass This component profiles the MetricsService 's summary resource metrics (load average, tcp use, etc).
ServiceFinder.javaClass A utility class to simplify late-binding service lookup.
ServiceProviderBase.javaClass A base class for ServiceProvider s.
Throughput.javaClass This component profiles the aggregate "messages per second" throughput for all agents on the local node.
TrafficMatrix.javaClass This component profiles the agent traffic matrix for all local-to-local and local-to-remote agent messaging.
VmStat.javaClass This component profiles the output of the "/usr/bin/vmstat" command, which summarizes the system performance.
