A reporting task in Nifi which is capable of sending monitoring statistics as prometheus metrics to a prometheus pushgateway. After this, the Prometheus server scrapes the metrics from the pushgateway.
For setting up the requirements there is a docker-compose file in docker/prometheus, that sets up the Pushgateway, the Prometheus server and a Grafana server. After starting the docker containers nifi needs to be downloaded and the ReportingTask has to be copied into the lib directory.
A sample dashboard can be found here: Sample Dashboard
- The Prometheus server runs under: http://localhost:9090
- The Pushgateway runs under: http://localhost:9091
- The Grafana instance runs under: http://localhost:3000
After setting up a simple flow and the ReportingTask, the flow can be started and the results should be visible in the Grafana dashboard.
To test or use the PrometheusReportingTask the following systems should be setup and running.
- Running Prometheus instance
- Running Prometheus Pushgateway instance
- Running Nifi instance
The tools can be setup with Docker or manually.
The project can be build with maven as the standard fasion of building nifi-processor-bundles.
The previously built .nar archive has to be copied into the nifi/lib directory and can be used after a restart of nifi.
To restart Nifi execute:
./nifi/bin/nifi.sh restart
