Configuration of ARSWMemUsageTest

Often, in environments where Arista Switch is deployed, unavailability and poor performance of the switch can adversely impact inter-device communication. If not detected and resolved quickly, such issues can snowball and degrade performance of mission-critical applications in the target environment. This may directly impact the reputation and business revenue of the environment. To avoid such adversities, it is important to monitor the operations of the Arista switch continuously.

This test monitors the memory utilization of the Arista Switch and proactively alerts administrators to potential memory contention, if any.

The default parameters associated with this test are:

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

• In the HOST text box, specify they address of the Arista Switch that is being monitored.

• Besides SNMP, this test also uses the Arista Switch CLI to pull metrics. To run the CLI commands, the test first needs to establish an SSH connection with the Arista Switch. To enable the test to establish this connection, specify the port in the SSH PORT text box.

• This test uses the Arista Switch CLI to pull metrics. To use the CLI, the test first needs to connect to the Arista Switch via SSH, and then run commands using CLI. For running the commands, this test requires the privileges of a valid SSH user with permission to run the CLI commands. Specify the user name and password of such a user against 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.

• If multiple components of the same component type are awaiting configuration, then an APPLY TO OTHER COMPONENTS button will appear in this page. Clicking on this button will allow you to apply the configuration to all/selected components of that type.

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

When changing the configuration for specific servers, a “*” beside the text box corresponding to the parameter signifies that these values have to be manually configured by the user. The parameter values that require to be configured will typically be prefixed with a “$” or contain a series of “*”. A value of “none” in the parameter value indicates that the corresponding parameter value can be changed if required.
