I have followed Nagios Core - Using Grafana With PNP4Nagios for Fedora, as well as tried the OMD version. The data source seems to add fine. When I setup a dashboard, following the ones listed. I get no data, further I dont knowhow ot show say CPU load returned by a plugin in Grafana. Could someone point me to a resource?
Is it a new installation, if this is the case i would recommend using prometheus, there is also already built dashboards you can try. You can either use :
- Node Exporter
- Nimon (njmon)
Note : If you already have a nagios infrastructure, make sure you have the data on the source before trying to connect it to grafana.
Also try the explore mode (dashboards are often built for a specific datasource)
It is an existing installation, with about 6 months of data in graphs.
Does it show any data using the Explore screen from your datasource ?
When I click host its empty, same for the other fields.
Thank you for your help, Im new to this, even though I read the docs, some doesn’t make sense.
