I recently started exploring OpenTSDB for monitoring a cluster that we have in our development environment. As a newbie, I have not delved deep into it, but was wondering if anyone successfully used OpenTSDB to monitor those.

Any pointers is helpful.

tcollector seems to have some iostat hooks in it, I will explore that and try to mimic similarly for ohter metrics – Avid Oct 17 '12 at 11:57

OpenTSDB has a child project to help collect system data from Linux servers and report it to OpenTSDB, called tcollector.

It's a simple data collection system written in Python, and it comes with a dozen+ collectors out of the box, including collectors for vmstat and iostat data. On a standard Linux server you'll get over a hundred system metrics.

OpenTSDB is basically built to handle very large amounts of monitoring data, so it is really only applicable if you monitor hundreds over servers, and you want to keep data in full fidelity indefinitely.

If not, you should really look into stuff like CollectD or Graphite.
