Installing Prometheus, Node Exporter and Enabling Ceph Prometheus Module on Focal

1. Configure your Ceph Cluster using QuantaStor version 6.1 for Focal.

Run the following script to install Prometheus and dependencies. This script will also enable Ceph Prometheus Module.

2. Running the installer. Enter the following command from a console on one of your Ceph nodes.

install-ceph-prometheus

You have now successfully installed Prometheus, Node Exporter and Enabled Ceph Prometheus Module

Let us begin the grafana setup now

1. Login to Grafana (http://Your Server IP or Host Name:3000) with default username and password as admin. Click in the 'Toggle Menu' option in the upper left hand side of Grafana to see the menu system.

2. Hover the mouse over the Gear icon and click the ‘data sources’ menu item to add a new Prometheus data source

3. Click ‘Add data source’ and Select Prometheus

4. Enter URL of Prometheus (node that you ran the 'install-ceph-prometheus' on) and set the HTTP Timeout to 60 and the Scrape Interval to 15s. Click Save & Test.

For example, http://10.0.16.60:9090. Note: those dimmed grayed-out default on this page are Grafana’s default suggestions and not actual values, you must enter in a value. Values will be shown in a white font.

After clicking Save & Test you should see the status:

5. Hover the mouse over the Dashboards icon, and click on the Import menu item. If the Import menu item is no longer present in the version of Grafana you are using, then from the menu system click 'Dashboards' -> click 'New' dropdown -> and select 'Import'. Enter the Ceph cluster Grafana dashboard id "7056" in the ‘Import via Grafana.com’ field and click Load.

6. Optionally change the Name field and select the Ceph Prometheus data source you just added in the previous step.

Finally, we have successfully integrated our Ceph Cluster with Prometheus, Node Exporter and Grafana!

Ceph Cluster #7056

Using this setup process, you can now monitor your Ceph cluster and import other similar Grafana dashboards.

Other Ceph Dashboards tested that work following the same import process:

CephFS #9340

Ceph - OSD (Single) #5336

Ceph Pools #5342
