Setting Up JMeter PerfMon Plugins for GUI and Non-GUI Server Performance Monitoring

Prerequisite: install the required JMeter PerfMon plugins.

1. jpgc-perfmon-2.1.zip (for the local machine).

2. ServerAgent-2.2.1.zip (to be deployed on the target server).

The tutorial uses Apache JMeter 3.2.

GUI monitoring of server performance

Steps:

Unzip ServerAgent-2.2.1.zip on the server, then run startAgent.sh (Linux/macOS) or startAgent.bat (Windows) to start the PerfMon Server Agent.

Unzip jpgc-perfmon-2.1.zip , copy all JAR files from its lib directory into JMeter’s lib folder.

After restarting JMeter, the GUI shows a new Plugins Manager menu and the listener jp@gc - PerfMon Metrics Collector , allowing you to add the target server’s IP, port and desired metrics.

Non-GUI monitoring of server performance

Because the GUI consumes additional resources, it is recommended to run tests in non-GUI mode.

Create a test plan file (e.g., xxx.jmx ) that includes the PerfMon Metrics Collector with the server’s IP, port and metric definitions. Also specify the output file for collected data, e.g., log.jtl .

Execute the test in non-GUI mode:

jmeter -n -t xxx.jmx -l log.jtl -JforcePerfmonFile=true

When the run finishes, the raw data are stored in log.jtl . You can generate a summarized result file ( result.jtl ) and open it in the JMeter GUI to view charts and tables of CPU, memory and other metrics.
