One bit of immaturity I just remembered: InfluxDB does a terrible job of telling you when you've fat-fingered a query. You can select from a series that doesn't exist or reference a tag that doesn't exist inside a 'where' clause, and InfluxDB will happily return 0 results instead of giving an error.

I've spent some time trying to figure out why I'm not getting data, and it turns out that it was because I typoed the name of the series.

I still like Influx though, warts and all.
