SDX Hardware Sensors - Voltage Test

If mission-critical hardware components of the SDX appliance - eg., CPU cores - experience severe and frequent voltage fluctuations, it can cause serious damage to the components. This in turn can render the SDX appliance unusable. To ensure the continuous availability and usage of the SDX appliance, administrators should keep an eye on the voltage of current passing through its core hardware components at all times, capture a voltage surge as soon as it occurs, and correct it immediately. This is where the SDX Hardware Sensors - Voltage test helps administrators!

This test reports the voltage of each hardware component on the SDX appliance and also reveals the state of that component in terms of voltage. This way, the test brings sporadic spikes in voltage and its impact on hardware health to the immediate attention of administrators, thereby urging instant remedial action.

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 component on 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 hardware component, in terms of voltage.

 

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

The value Error for this measure indicates that the current voltage value is out of range.

Note:

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

Current voltage

Indicates the current voltage of this hardware component.

Volts

An unusually high value for this measure is a cause for concern as it could indicate a potential hardware failure.
