This topic describes the Desktone_ApplicationServerStatistics CIM provider.
- Description
There will be a single instance of this class for all of the application appliances (that is, 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 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 VMware support.
