SDX Throughputs Test

When users complain of slowness of the SDX appliance, administrators should first check the throughput of the appliance. Throughput reveals how well/badly the appliance processes network traffic. Low throughput is indicative of a traffic processing bottleneck, which can cause users to experience slowness when interacting with the appliance. To receive real-time insights into the throughput of the SDX appliance, administrators can use the SDX Throughputs test. This test measures the throughput of the SDX appliance in real-time and alerts administrators if the throughput is low. Additionally, the test also reveals where the bottleneck is - when processing incoming network traffic? or outgoing network traffic?

Target of the test : A NetScaler SDX

Agent deploying the test : A remote agent

Outputs of the test : One set of results 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

Input throughput

Indicates the rate at which the SDX appliance processes incoming network traffic.

Mbps

If the value of the Total throughput measure is abnormally high or is increasing consistently, you may want to compare the value of the Input throughput and Output throughput measures to understand when the maximum slowness occurred - when processing incoming traffic? or when processing outgoing traffic?

Output throughput

Indicates the rate at which the SDX appliance processes outgoing network traffic.

Mbps

Total throughput

Indicates the rate at which the SDX appliance processes network traffic.

Mbps

This is the sum of the Input throughput and Output throughput measures and reveals the overall network throughput of the appliance.

A consistent drop in the value of this measure could indicate that the appliance does not have adequate bandwidth resources for processing network traffic.
