HMC Processor Test

This test keeps track of CPU usage by the HMC server and be proactively alerted to any processor contention with the help of this test.

Target of the test : An IBM HMC server

Agent deploying the test : A remote agent

Outputs of the test : One set of results for each processor supported by the HMC server.

Configurable parameters for the test
Parameter	Description
Test Period	How often should the test be executed.
Host	The host for which the test is to be configured.

Measurements made by the test
Measurement	Description	Measurement Unit	Interpretation
CPU utilization	Indicates the percentage of CPU resources utilized by the user processes executing on the HMC server.	Percent	A high value is indicative of excessive CPU usage by user processes.
System CPU utilization	Indicates the percentage of CPU resources utilize for system-level processing.	Percent	A high value is indicative of excessive CPU usage by the core system processes.
Idle CPU	Indicates the percentage of time for which the processor was idle	Percent	A very high value is often indicative of an under-utilized processor.
IO Waits	Indicates the percentage of time the processor was idle waiting for I/O processing to complete.	Percent	Comparing the value of this measure with that of the CPU utilization, System CPU utilization, and Idle CPU measures, will enable you to identify exactly where the HMC server has spent the most of its CPU resources, and why.
Swap memory	Indicates the amount of swap space currently available on the HMC server.	MB	An unusually high value for the swap usage can indicate a memory bottleneck. Check the memory utilization of individual processes to figure out the process(es) that has (have) maximum memory consumption and look to tune their memory usages and allocations accordingly.
