A note on SSL/TLS certificates. If you have an SSL certificate for LibreNMS, you can use it for grafana. If you run into issues, try copying the cert (fullchain.pem, privkey.pem) to /etc/grafana/
In Grafana, go to Configuration -> Data Sources -> Add data source
Set Name for Data Source
URL should be https://your_librenms_url/api/v0
Add Custom HTTP Header
Header field should be “X-Auth-Token”
Value field should contain the API token we created in LibreNMS
Save and Test If you receive any errors, refer to the Troubleshooting part at the end.
Adding LibreNMS API Data Source in Grafana
Add RRDReST Data Source
In Grafana, go to Configuration -> Data Sources -> Add data source
Set Name for Data Source
URL needs to be your docker container IP address (Steps above)
Save and Test (Should return “Unprocessable Entity”)
Adding RRDReST API Data Source in Grafana
Import Dashboard into Grafana
Now we need a dashboard to present our data.
Go to Create -> Import
Upload JSON file (Download from here or PasteBin )
Under RRDReST API , select our RRDReST Data Source
Under LibreNMS API , select our LibreNMS Data Source
Click Import
You should now be able to view your dashboard and use the drop down menus to select devices
Grafana viewing bandwidth on device being monitored by LibreNMS
Troubleshooting
There were a couple of issues I ran into while trying to get everything working together.
RRDReST shows 404 Not Found
Issue: When trying to run RRDReST with uvicorn, I was never able to access the rrd files, even the test rrd files that are included when installing RRDReST. I am guessing it is either a permisions issue, or something unable to access the files. Work around: Install RRDReST via Docker container.
Error Running uvicorn RRDReST
Error Adding LibreNMS API
Issue: Get a “JSON API: Bad Request” when trying to set up the LibreNMS API Data Source in Grafana.
Work around: Install a valid SSL Certificate and set up a DNS record so you can access LibreNMS at librenms.yourdomain.com.
More info: I would assume that “Skip TLS Verify” would work with or without a valid certificate, but it would not work for me. There are potentially some other options with modifying how Nginx or Apache is set up that would get this working. If you setup Grafana to use a SSL certificate, you may need to copy the certificate files (fullchain.pem, privkey.pem) to /etc/grafana/ and run “chown root:grafana *.pem” to let grafana have access to the files.
