Performance Monitor Description Default Value Garbage Collection Rate of a Monitors the rate at which 5 collections per sampling Java EE Application Server garbage collections are interval. happening on the JVM associated with the Java EE Application Server. Garbage Collection Time of a Monitors the time that the 5000 milliseconds per Java EE Application Server garbage collector takes to sampling interval. perform garbage collections on the JVM associated with the application server. Performance monitor for the Monitors the percentage of 90% Percentage of Virtual Machine used heap memory compared Memory Used on a Java EE to maximum heap memory on Application Server an application server. The garbage collection monitors (2 and 3) are for each garbage collector. You can have multiple sets of garbage collection monitors. To enable and configure performance counters 1. In the Operations console, click Monitoring. 2. Expand Application Monitoring, then Java Monitoring, then WebLogic Application Servers, and select the Performance folder. 3. one of the performance counters to be configured, and select Show or edit rule properties. 4. On the Monitor Properties dialog, on the Overrides tab Override. If you choose the memory monitor, you can either override the monitor for this application server or for all deep monitored application servers. If you choose a garbage collection monitor, you can either override the monitor for this garbage collector or for all garbage collectors in all application servers. You can also create groups for greater control in your configuration as you can with any other monitor in Operations Manager. 5. In the Override Properties dialog, enable the monitor and configure its threshold (and properties as necessary) and apply your changes. 6. Refresh Health Explorer, it may take a few minutes before you can see that the performance counter monitor is now enabled.
