Overview
+ +LibreNMS is a great network device monitoring system, and Grafana is a w=
+onderful tool for visualising and alerting on data from multiple sources.
However, while LibreNMS does provide official integration with many external d=
+atabases that you can then use as a data source in Grafana, if you don=E2=
+=80=99t already have one of these in your environment it requires you to de=
+ploy these as well.
+I=E2=80=99ve also personally run into performance issues with the Prometheus Pu=
+shgateway integration when pushing a large number of metrics, probably =
+because Pushgatew=
+ay isn=E2=80=99t designed for that use case.
Recently I stumbled upon a Reddit post=
+ by user /u/wjhinz which described a method for =E2=80=9C(almost) nativ=
+ely=E2=80=9D using LibreNMS as a data source in Grafana by using RRDReST as an API endpoint to acces=
+s the RRD files that LibreNMS creates.
+After testing this and confirming it works very well, I wanted to add to th=
+e Reddit post by documenting what a containerised deployment of this soluti=
+on looks like.
Major kudos to both /u/tb= +otnz (for their work on RRDReST) and /u/wjhinz (for documenting this solution).
+ +Containerised Deployment
+ +LibreNMS
+ +I=E2=80=99ll be using Docker Compose for this deployment, and starting w=
+ith the LibreNMS docker example compose file as the=
+ base.
+I=E2=80=99ve trimmed some services that aren=E2=80=99t needed (mstpd, syslo=
+g and SNMP traps), and included my compose file in an appendix section.
RRDReST
+ +Next, we want to add an RRDReST container. As a container image doesn=E2=
+=80=99t currently exist, we will need to create one.
+Thanks to tbotnz, who has provided instructions on how to get RRDReST running in his Git=
+hub repository, creating a container image is relatively easy.
+Here=E2=80=99s the Dockerfile I=E2=80=99ve written:
FROM python:3.10-alpine
+RUN apk add g++ make rrdtool
+COPY requirements.txt /opt/RRDRe=
+ST/requirements.txt
+WORKDIR /opt/RRDReST
+RUN pip3 install -r requirements.txt
+COPY . /opt/RRDReST
+ENTRYPOINT ["uvicorn", "rrdrest:=
+rrd_rest"]
+CMD ["--host", "0.0.0.0", "--por=
+t", "9000"]
+I=E2=80=99ve built the container using this and pushed it to be pulled from Docker Hub<= +/a> as well.
+ +To add this to our deployment, we simply need to add another service to =
+the docker-compose.yml=
+ file and give the container access to the LibreNMS volume (so it ca=
+n read the RRD files).
+I=E2=80=99m using /opt=
+/librenms as the mount point for the volume, as it mimics where data=
+ would be located in a non-containerised deployment.
services:
+ ...
+ rrdrest:
+ image: michaelwadman/rrdrest:latest
+ container_name: rrdrest
+ volumes:
+ - "./librenms:/opt/librenms"
+ As /u/wjhinz notes in their post, RRDReST needs read access to the RRD f= +iles, which should be fine with a docker-compose set up like this, but coul= +d be a good place to start investigations if it isn=E2=80=99t working for y= +ou.
+ +Grafana
+ +Finally, we want to add a Grafana container.
+ +services:
+ ...
+ grafana:
+ image: grafana/grafana-oss:latest
+ container_name: grafana
+ ports:
+ - target: 3000
+ published: 3000
+ protocol: tcp
+ environment:
+ - "GF_INSTALL_PLUGINS=3Dmarcusolsson-json-datasource"
+ Note that I=E2=80=99m adding an environment variable for the installatio= +n of the JSON API plugin, as this is needed to interact with both th= +e LibreNMS API as well as the RRDReST API.
+ +docker-compose up
+ +With a complete compose file, we can spin up the environment:
+ +$ =
+sudo docker-compose up -d
+Creating network "librenms_grafana_default" with =
+the default driver
+Creating librenms ... done
+Creating grafana ... done
+Creating librenms_db ... done
+Creating librenms_dispatcher ... done
+Creating librenms_redis ... done
+Creating librenms_memcached ... done
+Creating rrdrest ... done
+Adding data sources in Grafana
+
+Creating LibreNMS user
+
+
To add LibreNMS as a data source in Grafana, we first need to create an =
+API token in LibreNMS.
+Visit the LibreNMS web interface and log in (in my case, =E2=80=9Chttp://12=
+7.0.0.1:8000=E2=80=9D, with the default credentials of librenms/librenms).<=
+/p>
+
+
Because Grafana will only require read access, we=E2=80=99re going to cr=
+eate a new user with read-only access and then associate the token we creat=
+e with that user.
+Under =E2=80=98Settings -> Manage Users=E2=80=99, I created a user named=
+ =E2=80=9Cgrafana=E2=80=9D, changed the access level to =E2=80=9CGlobal Rea=
+d=E2=80=9D and set a random password as we will only be using the API acces=
+s.
![3D"Cr=](3D"https://wadman.co.nz/img/librenms-create-user.png")
![](3D"https://wadman.co.nz/img/librenms-user-configuration.png")
Then, under =E2=80=98Settings -> API -> API Settings=E2=80=99, I c= +reated an API token for the grafana user:
+ +![+=3D"Creating](3D"https://wadman.co.nz/img/librenms-create-api-token.png")
![3D"Libr=](3D"https://wadman.co.nz/img/librenms-api-token.png")
Make sure to copy the token when creating it, as we=E2=80=99ll need that= + later when adding the data source into LibreNMS.
+ +Adding LibreNMS data sour= +ce in Grafana
+ +After logging into the Grafana web interface (in my case, =E2=80=9Chttp:=
+//127.0.0.1:3000=E2=80=9D, with the default credentials of admin/admin), na=
+vigate to =E2=80=98Configuration -> Data Sources=E2=80=99 from the left =
+pane.
+Add a new data source and select the JSON API type from the list.
In the settings for the LibreNMS API data source, we need to change the =
+URL and add the token authentication header.
+The URL should be set to your LibreNMS host and port, with the API endpoint=
+ of =E2=80=9C/api/v0=E2=80=9D appended.
+Then, under =E2=80=9CCustom HTTP Headers=E2=80=9D, select =E2=80=9CAdd Head=
+er=E2=80=9D. The header name will be =E2=80=9CX-Auth-Token=E2=80=9D and the=
+ value will be the token string that you created above.
+Save and test that the API endpoint is working for you, and you should get =
+a green =E2=80=9CSuccess=E2=80=9D pop-up if everything is working.
My data source looked like the following when finished:
+ +![](3D"https://wadman.co.nz/img/grafana-librenms-datasource.png")
Adding RRDReST data source= + in Grafana
+ +Like the above, we=E2=80=99re going to also add the RRDReST API as a new=
+ data source in Grafana too.
+This will also be a JSON API, so select this from the data source type when=
+ creating it.
In the settings for the RRDReST API data source, we only need to change =
+the URL.
+Again, point this towards your RRDReST container host and port, and leave t=
+he endpoint blank.
+Save and test that the API endpoint is working for you, and you should get =
+a red =E2=80=9CUnprocessable Entity=E2=80=9D pop-up if everything is workin=
+g. This error means the API is reachable, but the plugin can=E2=80=99t proc=
+ess the data returned (which is expected, because there isn=E2=80=99t any d=
+ata returned, as we haven=E2=80=99t pointed it to an RRD file yet).
My data source looked like the following when finished:
+ +![+=3D"Grafana](3D"https://wadman.co.nz/img/grafana-rrdrest-datasource.png")
Creating a dashboard
+ +The last thing to do is to create a dashboard for the LibreNMS data to b=
+e visualised.
+From the left pane in Grafana, select =E2=80=98Create -> Import=E2=80=99=
+ and then upload the JSON file cr=
+eated by /u/wjhinz on Pastebin. I=E2=80=99ve also included it in an app=
+endix section below in the case that the Pastebin link goes away for some r=
+eason.
After import, you=E2=80=99ll be prompted to name the dashboard, place it= + into a folder and select the data sources you created before. Here=E2=80= +=99s what mine looked like before import:
+ +![3D"Grafana](3D"https://wadman.co.nz/img/grafana-rrdrest-dashboard-import.pn=)
There was one last item that I needed to change to get data displayed on=
+ the graph panels, which was to set the timezone to UTC. I believe this is =
+needed because LibreNMS stores (or RRDReST represents) data in UTC format, =
+but Grafana queries it with the local browser timezone by default.
+To do so, drop-down the time picker from the top right of the dashboard scr=
+een, select =E2=80=9CChange Time Settings=E2=80=9D and choose UTC.
![+=3D"Grafana](3D"https://wadman.co.nz/img/grafana-dashboard-timezone.png")
If you=E2=80=99ve got devices in LibreNMS, they should appear up the top= + left of the page in a drop down menu along with a list of interfaces. Afte= +r selecting a device and an interface, both the =E2=80=9CBandwidth In/Out= +=E2=80=9D and =E2=80=9CErrors In/Out=E2=80=9D graphs will populate with inf= +ormation:
+ +![3D"Grafana](3D"https://wadman.co.nz/img/grafana-rrdrest-dashboard-graphs.pn=)
While the panels in the dashboard provided only show port throughput and=
+ errors, it=E2=80=99s pretty easy to pick up the other RRD files in a devic=
+e directory and display those statistics as well.
+For example, LibreNMS has created 64 other RRD files full of stats for my t=
+est device:
$ =
+sudo docker exec -it rrdrest ls /opt/librenms/rrd/
+Test_Device
+$ sudo docker exec -it rrdrest ls /opt/librenms/rrd/Test_Device/ | grep -v port | wc -l
+64
+Conclusion
+ +Providing RRDReST access to the RRD files that LibreNMS creates is not o=
+nly easy, but it performs well too.
+If you are already using Grafana in your environment to visualise, analyse =
+and/or alert on data in a centralised fashion, then pulling SNMP metrics in=
+ through LibreNMS (and its=E2=80=99 device discovery feature) from devices =
+that are otherwise unmonitored and using RRDReST as a data source is a grea=
+t =E2=80=9Cquick win=E2=80=9D.
