+Description: statistics collection daemon (mbmon plugin)
+ collectd is a small daemon written in C for performance. It reads various
+ system statistics and updates RRD files, creating them if necessary. Since
+ the daemon doesn't need to startup every time it wants to update the files
+ it's very fast and easy on the system. Also, the statistics are very fine
+ grained since the files are updated every 10 seconds.
+ .
+ This package contains the mbmon plugin which collects motherboard status
+ information: temperatures, voltages and cooling fan speeds.
