PPM Center provides a stand-alone tool named Watchdog, which monitors the memory space through the GC log that the PPM Server generates. If the memory used after garbage collection is greater than a set threshold value, the Watchdog issues a command to generate a thread dump, and the thread dump is captured in the server log. You can configure the Watchdog tool to send out email notifications about this event.
It is recommended that you enable Watchdog as a diagnostic tool only if memory issues are surfacing in your PPM Center instance. For detailed information about the Watchdog, including instructions on how to use it, see the Installation and Administration Guide.
Note: Watchdog is not supported on AIX operating systems.
