A JMeter plug-in that enables you to send test results to Azure Application Insights.

Overview

Description

The following test results metrics are exposed by the plugin.

• TestStartTime
• SampleStartTime
• SampleEndTime
• ResponseCode
• Duration
• URL
• SampleLabel
• SampleCount
• ErrorCount
• Bytes
• SentBytes
• ConnectTime
• IdleTime
• ThreadName
• GrpThreads
• AllThreads

Plugin installation

Once you have built or downloaded the plugin JAR file from the releases section, move the JAR to your $JMETER_HOME/lib/ext.

mv target/jmeter.backendlistener.azure-VERSION.jar $JMETER_HOME/lib/ext/

Then, restart JMeter and the plugin should be loaded.

JMeter configuration

To make JMeter send test result metrics to Azure Application Insights, in your Test Pan, right click on Thread Group > Add > Listener > Backend Listener, and choose io.github.adrianmo.jmeter.backendlistener.azure.AzureBackendClient as Backend Listener Implementation. Then, in the Parameters table, configure the following attributes.

Attribute	Description	Required
instrumentationKey	The Instrumentation Key of your Application Insights instance	Yes
testName	Name of the test. This value is used to differentiate metrics across test runs or plans in Application Insights and allow you to filter them.	Yes
liveMetrics	Boolean to indicate whether or not real-time metrics are enabled and available in the Live Metrics Stream. Defaults to true.	No
samplersList	Optional list of samplers separated by a semi-colon (;) that the listener will collect and send metrics to Application Insights. If the list is empty, the listener will not filter samplers and send metrics from all of them. Defaults to an empty string.	No
useRegexForSamplerList	If set to true the samplersList will be evaluated as a regex to filter samplers. Defaults to false.	No

Example of configuration:

Visualization

Test result metrics are available in the requests dimension of your Application Insights instance. In the image you can see an example of how you can visualize the duration of the requests made during your test run.

Additionally, if you enabled liveMetrics in the configuration, you can watch your test performance in real-time in the Live Metrics Stream blade.
