Raspberry Pi Collectd Server and CGP GUI

In this series of posts I'll try to explain how to set up a working Collectd infrastructure, Monitoring data will be sent to a central computer (Raspberry Pi running Raspbian, called MainPi) and clients will be configged to send their data to the MainPi.


This post is about the Collectd Server ... called mainpi here

MainPi will also be configged to run CGP (Collectd Graph Panel) so we have a nice grapical representation of the data, that will be the 3rd post in the series

Getting collectd installed on the central server (MainPi) is a easy as typing:

sudo apt-get install collectd collectd-utils

Next step is to config the deamon as a network server using rrd as it's output.

sudo nano /etc/collectd/collectd.conf

## /etc/collectd/collectd.conf  Hostname MainPi FQDNLookup false ## This can be higher if you have a more powerfull box Interval 30 ## This can be higher if you have a more powerfull box ReadThreads 1 LoadPlugin syslog <Plugin syslog>         LogLevel info </Plugin> LoadPlugin cpu LoadPlugin df LoadPlugin disk LoadPlugin entropy LoadPlugin interface LoadPlugin irq LoadPlugin load LoadPlugin memory LoadPlugin processes LoadPlugin rrdtool LoadPlugin swap  LoadPlugin users LoadPlugin network                                                                                                                                            ## Server config                                                                                                           <Plugin "network">     # Can also be "*" "25826" to listen on 0.0.0.0    Listen "192.168.1.147" "25826" #Local interface    ReportStats true                                                  SecurityLevel None                                             </Plugin>                                                        ## Extra Plugins ## remove to disable                             #LoadPlugin nginx LoadPlugin uptime LoadPlugin ping                                                  <Plugin rrdtool>          DataDir "/var/lib/collectd/rrd" </Plugin> Include "/etc/collectd/filters.conf" Include "/etc/collectd/plugins.conf" Include "/etc/collectd/thresholds.conf"

Since Plugins.conf is loaded , well need to config the plugins in that file.

sudo nano /etc/collectd/plugins.conf

## /etc/collectd/plugins.conf ## Static Plugins (every host has them) <Plugin swap>        ReportByDevice false </Plugin> ## Dynamic Plugins (loaded by Ansible based on options) #<Plugin nginx> #       URL "http://127.0.0.1/nginx_status" #</Plugin> <Plugin ping>        Host "ntp.belnet.be" </Plugin> #</Plugin>

Thats the Collectd server set up !
