Description: collectd module for libsensors.
collectd module to collect system temperatures.
+
+Package: collectd-multimeter
+Architecture: any
+Depends: collectd (= ${Source-Version}), ${shlibs:Depends}
+Description: statistics collection daemon (multimeter 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 multimeter plugin which collects values from a
+ multimeter connected to a serial port.
