collectd – The system statistics collection daemon

collectd is a daemon which collects system performance statistics periodically and provides mechanisms to store the values in a RRD files. It comes with more than 90 Plug-ins, which helps to process, store and present the data in the way we want.

collectd utilizes a data push model. The data is collected and sent (pushed) to a multicast group or server. Thus there is no central instance which queries any values. collectd is able to handle any number of hosts, from one to several hundred.
