Package: munin-node
Version: 1.2.3-1
Severity: wishlist
I have modified the distributed ping_ plugin to be a little more
useful for monitoring. You can now add to your munin.conf something
similar to the following:
[ping_]
env.host www.google.com www.yahoo.com www.someother.host
and the plugin will ping each of these hosts, instead of just one.
This modification is incredibly useful if you are interested in using
munin to monitor hosts and alert if one is unavailable to the network.
