# Plugin to measure uptime. Especially the average and max values on the
# bigger graphs (yearly) can be interesting.

# This package has added support for NetBSD, via a number of new plugin
# scripts where specific steps needs to be taken to collect information.
#
# I also modified the ntp_ plugin script to make it possible to not
# plot the NTP poll delay, leaving just jitter and offset, which IMO
# produces a more telling graph.
#
#
#
# Magic markers - optional - used by installation scripts and
# munin-config:

#%# family=auto
#%# capabilities=autoconf
