SDX Resources - Hardware Test

Hardware resources such as CPU, memory, NICs, disks, etc., are crucial to the uninterrupted functioning of the SDX appliance. If even one of these hardware components experiences errors or deviates from their normal behavior, it is bound to adversely impact the overall health and availability of the SDX appliance. This is why, it is imperative that administrators receive instant notifications of any abnormality related to the hardware resources. For this purpose, administrators can use the SDX Resources - Hardware test.

This test monitors and reports the operational state and overall health condition of each hardware resource such as CPU, disk, interface, etc. In the process, the test promptly captures and reports hardware-related abnormalities and ensures the timely intervention of administrators.

Target of the test : A NetScaler SDX

Agent deploying the test : A remote agent

Outputs of the test : One set of results for each hardware resource supported by the target NetScaler SDX.

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.

SDX Username and SDX Password

To monitor a NetScaler SDX device, the eG agent should be configured with the credentials of a user with read-only privileges to the target device. Specify the credentials of such a user in the SDX Username and SDX Password text boxes.

Confirm Password

Confirm the password by retyping it here.

SSL

The eG agent collects performance metrics by invoking NITRO (NetScaler Interface Through Restful interfaces and Objects) APIs on the target NetScaler SDX device. Typically, the NITRO APIs can be invoked through the HTTP or the HTTPS mode. By default, the eG agent invokes the NITRO APIs using the HTTPS mode. This is why, the SSL flag is set to Yes by default. If the target NetScaler SDX device is not SSL-enabled, then the NITRO APIs can be accessed through the HTTP mode only. In this case, set the SSL flag to No.

Measurements made by the test

Measurement

Description

Measurement Unit

Interpretation

Status

Indicates the current state of this hardware resource.

 

The values that this measure can report and their corresponding numeric values have been listed in the table below:

Measure Value Numeric Value
Ok 100
Error 0

If the value of this measure is 'Error' for a resource, it indicates a deviation from the expected value.

Note:

By default, this measure reports the above-mentioned Measure Values to indicate the current state of a hardware resource. However, in the graph of this measure, the Measure Values will be represented using their corresponding numeric equivalents only.

Current value

Indicates the current value of this hardware resource.

Number

 

Expected value

Indicates the expected value for this hardware resource

Number

A high value is desired for this measure.
