# Graphing metrics with Collectd and Jarmon

## Overview

I manage a few VPS, for personnal and professional use. I don't need any fancy supervision system like Nagios, Zabbix, ... But I Like to keep track of what happens/happened on my servers. A light solution for that is to setup __collectd__ to retrieve the data, and use one frontend, I chose __Jarmon__, to display them in a browser.

## Collectd

Two packages exists on Debian: `collectd` and `collectd-core`. The first one brings a lot of dependencies, so I will not use it.

    sudo aptitude install collectd-core

Graph a config file

    sudo cp /usr/share/doc/collectd-core/examples/collectd.conf /etc/collectd/
    sudo cp /usr/share/doc/collectd-core/examples/thresholds.conf /etc/collectd/
    sudo cp /usr/share/doc/collectd-core/examples/filters.conf /etc/collectd
    
Edit it as needed

    sudo vim /etc/collectd/collectd.conf

Restart collectd

    sudo service collectd restart


<note warning>To be continued...Jarmin needs a little tweaking to run smoothly. There's no auto-config/discover so... I will try Monitorix instead... might be faster to setup</note>
