Run Our Load Test and Analyze It

1. Before launching our test, one last tip is to ask JMeter to generate an HTML report at the end.

   For this, we will use the following command line:

   <JMETER_HOME>/bin/jmeter -n -t [jmx file] -l [results file] -e -o [Path\ to output folder]

2. Let's run our test and see what happens.

   In our terminal:

3. In Grafana (the dashboard used is one of those proposed in the Grafana website (https://grafana.com/dashboards/3351)):

   Note

   We can use this dashboard, too: https://grafana.com/dashboards/5496.

4. At the end of our test, we get the HTML dynamic Web Report with 17 graphs, an APDEX (https://en.wikipedia.org/wiki/Apdex) table, a statistics table (showing response times, error rates, network metrics…), a table with an errors summary, and a table with Top5errors per sampler. So, you get everything you need to analyze your load test:

The icing on the cake is a CSV file we get at the end of our test; this format is usable by many tools to visualize the results differently.

In this chapter, we have seen how to quickly get started with JMeter to perform a simple load test.
