Totally in the InfluxDB camp too.

I've spent the last week working on upgrading our Graphite system. I ultimately killed it and went with InfluxDB. The ease of installation and cluster creation were clear winners.

Additionally the storage options for Influx trump Graphite across the board. I tried writing a custom backend and it went nowhere. The docs and code are terrible. I also noticed that Ceres hasn't had a commit in a year - kind of disheartening.
