Memory Statistics Test

This test auto-discovers the stack units of the Dell EMC S-Series Switch and reports the memory utilization of each stack unit. By comparing the memory usage statistics across the stack units, administrators can quickly identify the stack unit that is currently running out of space.

Target of the test : A Dell S-Series Switch

Agent deploying the test : An external Agent

Outputs of the test : One set of results for every stack unit in the Dell EMC S-Series Switch to be monitored.

Configurable parameters for the test

Parameter	Description
Test Period	How often should the test be executed.
Host	The IP address of the host for which this test is to be configured.
SSH Username and SSH Password	Specify the credentials of a user who has the right to execute CLI (command-line interface) commands on the target switch and pull out metrics via SSH.
Confirm Password	Confirm the SSH Password by retyping it here.
SSH Port	The port at which the target switch exposes its SSH; The default value is 22.

Measurements made by the test

Measurement	Description	Measurement Unit	Interpretation
Total memory	Indicates the total amount of memory allocated for this stack unit.	MB
Used memory	Indicates the amount of memory that is utilized by this stack unit.	MB	A low value is desired for this measure. A value close to the Total memory measure indicates that the memory resources are depleting rapidly.
Free memory	Indicates the amount of memory that is currently available for use in this stack unit.	MB	A high value is desired for this measure.
Used memory utilization	Indicates the percentage of memory utilized by this stack unit during the last measurement period.	Percent	Compare the value of this measure across the stack units to figure out the stack unit that is consuming more memory space.
