As a follow-up evolution of this project we wanted something more flexible, with better detail, and also able to collect statistics from 7-Mode NetApps(OCPM is compatible with cDOTs only). Enter NetApp Harvest, a collection of Perl scripts provided by NetApp that collect a lot of statistics from 7-Modes, cDOTs and OCUMs, and send them to Graphite(and thanks to InfluxDB's "graphite compatibility mode", to InfluxDB as well). NetApp harvest is extremely flexible, you can add stuff you want to get data on and you can also change the frequence(by default it runs every minute - much better than OCPM's unchangable 5min).

In order for InfluxDB to be able to parse all that data, it needs templates, and in that case, the templates are pretty complicated.
Prerequisites
