Application Health Monitoring
Providers can have their applications request and manage system resources. Some of this resource utilization is persistent across, for example, reboots or the restart of the application. Some system tasks such as deleting a package, disabling and application, or accessing shared resources require that resources be cleaned up by entities other than the application itself. Resources that are known to need cleaning up include the following:
- GENCFG blobs
- SYSV shared memory segments
- SYSV semaphores
- Temporary files
Currently, the traceoptions statement is the only CLI statement available for configuring resource cleanup.
To configure tracing operations for resource cleanup operations, include the traceoptions flag option for selectively turning the debugging of trace messages on or off:
The available flags for the traceoptions statement include:
- all—Enable all trace option flags.
- events—Display process state change and cleanup events.
- gencfg—Display GENCFG blobs recorded for cleanup.
- sysvsem—Display SYSV semaphores recorded for cleanup.
- sysvshm—Display SYSV shared memory segments recorded for cleanup.
- ui—Display tracing messages for UI operational commands.
