System Statistics Test

This test continuously monitors the target delivery controller and measures the key performance metrics such as CPU utilization, the number of connections established to the delivery controller per second and the number of requests made to the delivery controller in one second.

Target of the test : An Array Application Delivery Controller

Agent deploying the test : A remote agent

Outputs of the test : One set of results for the Array Application Delivery Controller that is 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 that is being monitored.

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 delivery controller and pull out metrics via SSH.

Confirm Password

Confirm the SSH Password by retyping it here.

SSH Port

Specify the SSH port of the target delivery controller here; The default value is 22.

SSH Enable Password

The delivery controller offers three levels or modes using which the user can simply execute CLI commands on the ArrayOS. The modes are given below:

  • User Mode - In this mode, the user can execute the commands to perform the authorized and basic operations and non-critical functions on the ArrayOS.
  • Enable Mode - This mode enables the user to run the majority of commands for viewing data. To prevent unauthorized access to this mode, access should be password protected.
  • Config Mode - Using this mode, the user can change the configuration of the delivery controller for global configuration and access (Using commands).

The user can select any of these modes depending on his/her needs. If the user has selected the Enable Mode, he/she should specify a password in the SSH Enable Password text box to execute the commands.

In order to have access to most of the commands on the ArrayOS, administrator should select the Enable mode. Normally, you should enter a password to enter the Enable mode to restrict access to this mode. enable secret password uses stronger encryption when it is stored in the configuration file and it is more safe.

Confirm Password

Confirm the SSH Enable Password by retyping it here.

Timeout

Specify the duration (in seconds) within which the SNMP query executed by this test should time out in this text box. The default is 10 seconds.
Measurements made by the test
Measurement Description Measurement Unit Interpretation

CPU utilization

Indicates the percentage of CPU utilized by the delivery controller.

Percent

A high value for this measure is a cause of concern.

Connection per second

Indicates the number of connections established to the delivery controller in one second.

Number

 

Request per second

Indicates the number of requests made to the delivery controller in one second.
