Monitoring Resource Usage

This section provides additional information that may help you to interpret the information that Performance Monitor provides that is related to the events reporting resource usage on host machines. These events are:

• Event 150 (JVM Status).

• Event 151 (Network Status).

• Event 200 (Resources Per Process).

• Event 300 (Host Resource Status).

• Event 301 (Tuxedo "pq" Row).

• Event 302 (Tuxedo "psr" Row).

These events report the usage of machine resources (CPU, memory, network, and so on). These events, except for Event 150 (JVM Status), make calls to external APIs (often specific to the operating system) to retrieve metric information. The monitored system sends each event at the sampling interval that is specified for that system.
