I/O Waits Test

The IOWaits test reports the CPU utilization of processes waiting for input or output. This test works on Solaris, Linux, AIX, and HPUX platforms only.

Target of the test : Solaris, Linux, AIX and HPUX systems

Agent deploying the test : An internal agent

Outputs of the test : One set of results for the system being monitored

Configurable parameters for the test
  1. TEST PERIOD - How often should the test be executed
  2. Host - The host for which the test is to be configured
  3. duration - By default, this parameter is set to 5 seconds. This implies that, by default, the test will report the CPU usage of processes averaged across the 5 seconds.
