# Plugin for watching io-bound traffic (in transfers) on disks.

# autoconf (optional - used by munin-config)

# Revision 1.1.1.1 2006/06/04 20:53:57 he

# Import the client version of the Munin system monitoring/graphing
|
|
# tool -- project homepage is at http://munin.sourceforge.net/
|

|
|
# 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.
