Grafana Dashboard for Jmeter

0
votes

I am new to InfluxDB & Grafana. Currently we are performing load testing with Jmeter (5.2.1) and also utilizing InfluxDB (2.0) & Grafana for monitoring. The set up goes like - 1 Controller machine and 8 remote host machines (LGs).

Though we are getting the value generated in the grafana dashboard, the development / project team is interested in knowing which LG is returning how much error and even we are interested to know, is the performance same on each of the loaf gen .

Question is - Do anyone here in community have configured the Grafana dashboard in a way that, we get individual graph for each of the host machine / LG.

Already tried

  • Tried searching on google, but no suitable article found, if there is any, would request you to please share the link.
  • Also observed that, though the jmeter result file (jtl) file contains the host machine IP under the header - threadName, but the same is not found in influxDB when the query select * from jmeter was executed. Does it means that, the threadName / host machine IP needs to be explicitly entered into DB with a separate sampler .. ? if so, how can this be achieved ?
  • Tried building the query, but because of the limited knowledge in influxQL, not able to identify which keys / tags needs to be used

Sample of jmeter output in JTL file

If you can help on the building the dashboard, it would be of great help ..

Thanks in advance

If you look at Metrics Explosed chapter of the Real-time results user manual entry you won't see the "threadName" or similar metric anywhere.

It means that the name of the thread isn't getting stored in Graphite/InluxDB so there is no way to distinguish the load generator IP address in Grafana.

I can think of 2 possible options:

  1. Modify existing relevant AbstractBackendListenerClient and add a separate measurement holding the IP address of the load generator machine

  2. Add __machineIP() function as a prefix/postfix to your Sampler labels, in this case the sampler/transaction names will have the IP added and you will be able to filter them out in Grafana:
