Default Parameters for ARSWCpuUsageTest

One of the probable reasons for the poor performance of the target Arista switch is excessive CPU utilization. Administrators should hence continuously track how well the switch utilizes CPU resources, so that abnormal usage patterns can be proactively detected and corrected to ensure peak performance of the switch.

This test helps the administrators to monitor the CPU resource contention in the Arista switch and also helps to sort out the solutions for what caused this contention - resource-hungry user processes, CPU-intensive system processes or low-priority (Nice) jobs?

This page depicts the default parameters that need to be configured for the ARSWCpuUsageTest.

• The TEST PERIOD list box helps the user to decide how often this test needs to be executed.

• This test uses SSH commands to pull out the required metrics. To use these commands, the test first needs to connect to the target storage server via SSH. For running the SSH commands, this test requires the credentials of a user who is authorized to access the target switch via SSH. Specify the login credentials of such a user in the SSH USERNAME and SSH PASSWORD text boxes.

• Confirm the Password by retyping it in the CONFIRM PASSWORD text box.

• Specify the duration (in seconds) for which the SNMP query executed by this test should time out in the TIMEOUT text box. By default, this is set to 10 seconds.

• Once the necessary values have been provided, clicking on the UPDATE button will register the changes made.

When changing default configurations of tests, the values with “$” indicate variables that will be replaced by the eG system according to the specific server being managed - for instance, $hostName is the host/nickname of the target host, $port is the port number of the server being monitored. E.g., for a server xyz:80, $hostName will be changed automatically by the eG manager to “xyz*” and $port will be changed to “80” when configuring a test.
