# Plugin to monitor inode-usage.
#
# Parameters understood:
#
# config (required)
# autoconf (optional - used by munin-config)
#
# $Log: df_inode.in,v $
# Revision 1.2 2010/10/27 18:23:13 shattered
# Also ignore null and union filesystems, bump revision.
#
# 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.
#
#
#
#
# Magic markers (optional - used by munin-config and installation
# scripts):

#%# capabilities=autoconf
