JMeter Grafana Dashboard

Grafana Dashboard with InfluxDB for JMeter Performance Results

How To

Follow the given instructions to configure both JMeter and Grafana dashboards in your local environment.

Docker Grafana & InfluxDB

Execute the following docker-compose command from Docker directory to spin and run a set of containers with Grafana and InfluxDB as configured

# `-d` flag to detach the process and to run it in background
docker-compose up [-d]

Execute the following command to tail the logs of the containers if the docker-compose is executed with detach mode

docker-compose logs -f

Once the containers are started successfully, navigate to http://localhost:3000 to access the Grafana Dashboard. Enter the following credentials to log-in to the Grafana Dashboard

• Username: admin
• Password: admin

Import Dashboards

• Hover on the + symbol and select Import to import an existing Dashboard to the Grafana.
• Select the Upload JSON File option in the following screen and upload the grafana-jmeter-dashboard.json and import

Note: The Grafana is configured with InfluxDB datasource as default. Please follow the JMeter InfluxDB Configurations to configure an InfluxDB instance for the JMeter performance results.

JMeter InfluxDB Configuration

Once the Docker services are up and running, execute the following cURL command to create a database named jmeter_influx to store the performance metrics.

curl --location --request POST 'http://localhost:8086/query' \
    --header 'Content-Type: application/x-www-form-urlencoded' \
    --data-urlencode 'q=CREATE DATABASE jmeter_influx'

Configure Grafana with JMeter InfluxDB

Once the jmeter_influx DB is created successfully, sign-in to the Grafana Dashboard and perform the following to configure the jmeter_influx DB in the Grafana environment.

1. Hover the cogwheel icon and go to Datasources
2. Add data source > select InfluxDB and enter the following
   1. Name: JMeter InfluxDB
   2. URL: http://infuxdb:8086
   3. Database: jmeter_influx
   4. User: admin
   5. Password: admin
3. Click on Save & Test

JMeter

Next, configure the JMeter to send the performance metrics to the InfluxDB while performing a load test in your environment. This repo contains a simple sample JMeter script attached.

Perform the following to configure InfluxDB Backend Listener in JMeter

1. Add a Backend Listener to the JMeter script
2. Select the Backend Listener Implementation as org.apache.jmeter.visualizers.backend.influxdb.InfluxdbBackendListenerClient
3. Fill the following information
   1. influxdbMetricsSender: org.apache.jmeter.visualizers.backend.influxdb.HttpMetricsSender
   2. influxdbUrl: http://localhost:8086/write?db=jmeter_influx
   3. application: Provide an application name (ex: Mock Application)
   4. measurement: jmeter
   5. summaryOnly: Boolean value (ex. true or false)
   6. samplersRegex: .*
   7. percentiles: 90;95;99
   8. testTitle: Grafana Mock Test Plan
4. And save the script and perform a load testing

Once the load test is executed, navigate to the Grafana Dashboard and open our JMeter Dashboard. Select the ...

• JMeter-InfluxDB as the Datasource
• The Application name
• The Transaction

to view the performance metrics in realtime.
