Old man opinion here:
I really like grafana, personally I'd probably host it myself even now. (At all previous companies I did.) Its well contained and even with alerting its simple to set up and sync state (assuming you are using a hosted database, which can be expensive)
Where my opinion gets controversial: I dislike Prometheus, and I really don't like influx. I much prefer graphite.
Influx has higher temporal resolution, and an SQL interface (its the SQL interface I don't like)
Prometheus has a pull model, which I can see the appeal of, but I don't really like. But it deals with ephemeral metrics much better (however you need a gateway to cache the metrics, as they might not get pulled in time.)
The issue is that graphite's interface is much better for discovering and filtering/transforming your data. I'm not the worlds greatest SQL person, so I can't do that much complex stuff, I also don't know how to do maths in SQL well. With graphite I don't need to worry, all the functions are there in menu, derivative? yes, all the averaging? mostDeviant? yes.
Graphite made making graphs quick and easy, I don't think I can say the same for influx or prometheus. I know that all sorts of non technical people can use graphite/grafana. I'm less convinced that they can use Prometheus or influx as well without training.
