I was trying to interate Jmeter, influxDB and Grafana to see the test results.

I am running docker containers with below versions

INFLUXDB_VERSION=2.1.1
Grafana v8.5.0
Jmeter 5.4.1

After I create the data source in Grafana I can see one jmeter bucket which I created in InfluxDB. However the measurement i setup in Jmeter Backend Listener cannot see in the inFluxDB

Jmeter

influxdb

I believe due to this reason I can't see any query result Grafana explore as below

If you're running docker containers then I strongly doubt your InfluxDB URL of http://localhost:8086 is correct, you will have to use the container with InfluxDB IP address both in JMeter and in Grafana.

The IP address of the InfluxDB instance can be obtained using docker inspect command

Check jmeter.log file for any suspicious entries, you may also want to increase JMeter's logging verbosity for the Backend Listener implemenations by adding the next line to log4j2.xml file:

<Logger name="org.apache.jmeter.visualizers.backend" level="error" />

this way you will get more information regarding what's going on under the hood.

You may also find JMeter Integration with InfluxDB 2.0 guide useful.

Also be aware of JMeter InfluxDB v2.0 listener plugin where you can see useful queries snippets.

  • I hope you meant `http://localhost:8086 is incorrect`, BTW I tried container IP in Jmeter as well instead of localhost. Hwever in that case what I found was, in the grafana `Explore` window, flux query it wont show the bucket pre populated. I already using influxDB container IP in grafana. – Shabar Apr 26 '22 at 11:20

The reason for this is due to missing jmeter-plugin-influxdb2-listener-<>.jar plugin. Becuse influxdb version 2.0 or above needs this Jmeter plugin.

https://github.com/mderevyankoaqa/jmeter-influxdb2-listener-plugin.

Backend Listener : org.md.jmeter.influxdb2.visualizer.JMeterInfluxDBBackendListenerClient.

Here is the Grafana dashboard that can be used : https://grafana.com/grafana/dashboards/13644
