Elasticsearch listener for Apache JMeter

The listener plugin for Apache JMeter that enables delivery of samples' result data to Elasticsearch server using Elasticsearch API.

Usage of the plugin is described in SAP Community blog https://blogs.sap.com/2016/04/06/load-testing-with-jmeter-test-results-visualization-using-kibana-dashboards/.

Prerequisites

• Java runtime 1.8 or higher.

Dependencies

• Elasticsearch Java REST client library

Documentation: https://www.elastic.co/guide/en/elasticsearch/client/java-rest/index.html

Dependency declaration for Maven POM:

<dependency>
	<groupId>org.elasticsearch.client</groupId>
	<artifactId>elasticsearch-rest-client</artifactId>
	<version>7.1.1</version>
</dependency>
<dependency>
	<groupId>org.elasticsearch.client</groupId>
	<artifactId>elasticsearch-rest-high-level-client</artifactId>
	<version>7.1.1</version>
</dependency>

• Several libraries (such as HTTP client that is used by Elasticsearch Java REST client, JSON processor, logging framework) that are already a part of JMeter distribution (the statement is based on content of distribution of JMeter version 5.1).
• Here is an example maven command (linux) to download and copy all dependencies to JMeter lib folder. Assumes pom.xml file is in <JMETER_HOME directory. (Example pom.xml can be found at https://github.com/ImagineLearning/jmeter-container/blob/master/jmeter_home/pom.xml)

cd ${JMETER_HOME} \
&& mvn dependency:copy-dependencies \
&& cp target/dependency/* lib \
&& rm -rf target

Installation

• Copy dependency libraries to the directory /<JMeter home>/lib/.
• Copy plugin library to the directory /<JMeter home>/lib/ext/.

Parameterization

Parameter	Description	Default value

Additional notes

The listener plugin has been tested with JMeter version 5.1 running on JRE versions 1.8 and 1.9 in conjunction with Elasticsearch server version 7.1.1.
