In this chapter, we'll explore how you can monitor tests in real time with JMeter. As you start building more complicated and long-running test plans, it becomes imperative to capture and analyze your results in real-time to tighten the feedback loop and self-correct earlier rather than later. Without a real-time monitoring mechanism, you will have to wait for tests to run to completion before you can analyze the results. In most situations, this is not ideal.
Thankfully, JMeter provides extension points that allow you to send test plan results to a time-series database and view those results with an elegant GUI, which you can monitor in real-time.
We will be exploring how we can leverage InfluxDB and Grafana to monitor and analyze test plans in real time.
