I really liked Grafana, and I was using it for my personal servers monitoring, using collectd and InfluxDB, but recent updates changed everything, collectd became second class citizen with InfluxDB, and I was unable to replicate my queries with the new Grafana and InfluxDB.

I do not know if it is Grafana or InfluxDB faults (I guess IDB changed their API and Grafana followed), but I got lost.

I went back to plain RRDTool with a few static HTML pages with my graphs on it.

I don't know how you could this turning point where a tool become too complicated for "personal-pro" use, but I've seen this quite a lot (docker, chef.io, grafana).

I still think grafana is a great product, but it has sailed in the "enterprise" territory.
