Kcollectd is a small applications that allows to view rrd datacollections that have been created by collectd. It is quite limited as it only displays one datasource at a time, but allows to zoom and scroll around. It also has a status-monitor mode, where it automatic updates every 10 seconds. Ebuild will be attached for submission to sunrise.
