Created page with "== What is collectd ? == Collectd is a daemon which collects system performance statistics periodically and provides mechanisms to store the values in a variety of ways, f..."

New page

== What is collectd ? ==

Collectd is a daemon which collects system performance statistics periodically and provides mechanisms to store the values in a variety of ways, for example in RRD files. [http://collectd.org Website]

== Collectd config for OpenSim ==

As stated here : [[Monitoring Module]], we can get region statistics using the url : http://sim:port/monitorstats/UUID of the region or region name. We can use the collectd curl_xml plugin to get xml values and store them in a rrd file. To do this, we need to enable the curl_xml plugin and define some dataset types.

*Create a file /etc/collectd/my_types.db
*Edit the file and add inside (i have put only generic limits but feel free to edit this page and adjust the ranges) :
