Desktone_ApplicationServerStatistics

This topic describes the Desktone_ApplicationServerStatistics CIM provider.

• Description

  There will be a single instance of this class for all of the application appliances (this will not be present in DB appliances).

• Properties

  These properties report on operations of the JVM (Java virtual machine) used for the application.

  • InstanceID: Key to uniquely identify the instance of this class. Set to DesktonehostName_Jboss.
  • ThreadCount: Total number of threads running during the monitoring sample.
  • ThreadGroupCount: Total number of thread groups that exist during the sample time.
  • HeapSize: Current in-use size of heap memory.
  • MaxHeapSize: Maximum heap memory allowed on the application server.
  • Uptime: The length of time the application server has been running in milliseconds.

• Calculations

  • Heap size used: 100*HeapSize/MaxHeapSize. Recommendation is to warn at 85% and then increase the alert priority in 5% increments (that is, 90, 95, 100).

• Mitigation

  At 85%, schedule a restart of the dtService. At 90% or higher, restart the dtService immediately:

  $ service dtService restart
  

  If the heap memory used increases to high levels often (more than once per week), you should analyze your environment together with Customer Support.
