Resource Usage – Zone Test

This test monitors the CPU and memory usage of each zone (including Global zone) of a Solaris virtual server.

Target of the test : A Solaris virtual server

Agent deploying the test : An internal agent

Outputs of the test : One set of results for every zone executing on the Solaris virtual 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.
Port	The port number at which the specified host listens. By default, the port is NULL.
Connect Using	By default, this parameter is set to sudo. This indicates that, by default, this test uses the sudo command to connect to the Solaris virtual server and pull out metrics. If you want the test to use the pfexec command instead, select the pfexec option from the Connect Using drop-down.

Measurements made by the test

Measurement	Description	Measurement Unit	Interpretation
Processes running	Indicates the number of processes currently executing on this zone.	Number
Cpu usage	Indicates the percentage of CPU used by all the processes executing on this zone.	Percent	A very high value could indicate the existence of one/more CPU-intensive processes. Using the detailed diagnosis of this measure, you can quickly and accurately identify the top-10 processes that are consuming CPU excessively.
Memory usage	Indicates the percentage of memory utilized by the processes executing on this zone.	Percent	A sudden increase in memory utilization for processes may be indicative of memory leaks in the application.
Total size	Indicates the total virtual memory size of mappings within the processes executing on the zone.	MB
Resident size	Indicates the resident set size of the processes executing on the zone - i.e., the amount of physical memory mapped into the processes.	MB

The detailed diagnosis of the Cpu usage measure reveals the top-10 CPU-intensive processes executing on a zone.
