How to install plugin manager and perfmon metric collector on remote server in Non- GUI mode?

I have installed jmeter 5.2.1 on one of remote AWS server.

I want to collect summary report of response and server information as well with perfmon metric.

I have downloaded jmeter-plugins-manager-1.6.jar and jmeter-plugins-perfmon-2.1.jar and copied to /lib/ext

I then created a test script from jmeter on my local machine and copied to server and tried to run the same jmeter -n -t AWS.jmx -l awsresults.jtl

But I am getting an error as :

Error in NonGUIDriver java.lang.IllegalArgumentException: Problem loading XML from:'/root/apache-jmeter-5.2.1/bin/AWS.jmx'. 
Cause:
ClassNotFoundException: kg.apc.jmeter.vizualizers.CorrectedResultCollector

line number         : 219
version             : 5.2.1

When I run this on local machine in jmeter its working as expected.

Can someone please help me to understand and solve the error.?

Thanks,

Solution

  • The error means that you don't have the PerfMon plugin installed on your AWS instance, I don't think that the current version of JMeter Plugins Manager can detect/install the missing plugins in non-GUI mode so you will need to do this manually.

    Something like:

    1. Download JMeter Plugins Manager:

      wget https://jmeter-plugins.org/get/ -O /opt/apache-jmeter-5.2.1/lib/ext/jmeter-plugins-manager.jar

    2. Download JMeter Plugins Command Line Runner

      wget https://repo1.maven.org/maven2/kg/apc/cmdrunner/2.2/cmdrunner-2.2.jar -P /opt/apache-jmeter-5.2.1/lib/

    3. Install JMeter Plugins Manager Command Line Utility:

      java -cp /opt/apache-jmeter-5.2.1/lib/ext/jmeter-plugins-manager.jar org.jmeterplugins.repository.PluginManagerCMDInstaller

    4. Install the PerfMon Plugin:

      /opt/apache-jmeter-5.2.1/bin/./PluginsManagerCMD.sh install jpgc-perfmon

    5. That's it, now you should be able to execute your test

    P.S. According to JMeter Best Practices you should always be using the latest version of JMeter so consider upgrading to JMeter 5.4.1 or whatever its the current JMeter latest stable version
