SDX Hardware Sensors - Fan Test

If a fan cooling the SDX hardware malfunctions, it can cause the hardware temperature to soar and may even cause irreparable damage to the hardware. If this is to be avoided, the speed and state of each fan supported by the SDX appliance should be tracked, and administrators immediately notified of abnormalities. This is what the SDX Hardware Sensors - Fan test. This test monitors the speed and operational state of each fan the target SDX appliance supports and promptly alerts administrators if the fan experiences errors or if the speed of the fan increases abnormally.

Target of the test : A NetScaler SDX

Agent deploying the test : A remote agent

Outputs of the test : One set of results for each fan 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 status of this fan.

 

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

Numeric Value Measure Value
100 Ok
0 Error

If the value of this measure is 'Error' for a fan, 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 fan. However, in the graph of this measure, the Measure Values will be represented using their corresponding numeric equivalents only.

Current fan speed

Indicates the current speed of this fan.

Rpm

A sudden and steep increase in the value of this measure could indicate a fan failure.
