munin-node 2.0.71-2ubuntu1 (amd64 binary) in ubuntu lunar

 Munin is a highly flexible and powerful solution used to create graphs of
 virtually everything imaginable throughout your network, while still
 maintaining a rattling ease of installation and configuration.
 .
 This package contains the daemon for the nodes being monitored. You should
 install it on all the nodes in your network. It will know how to extract all
 sorts of data from the node it runs on, and will wait for the gatherer to
 request this data for further processing.
 .
 Munin is written in Perl, and relies heavily on Tobi Oetiker's excellent
 RRDtool. To see a real example of Munin in action, you can follow a link
