Hello
I need to integrate Nagios with Grafana. I read some old topics but I need a better explanation by someone who did it. I have some nagios that I want to connect with grafana to generate dashboards. I’ve saw many options to do this, by graphite, collectd, pnp4nagios etc… But what is the best way to do this?
Do you have a preference for a time series database like Influx or Prometheus?
I’ve never worked with both, but I know then
I’m looking for an open source solution, and the most “clean” (and effective) as possible!! 
What’s your suggestion?
Thanks for reply!!
