=head1 NAME

nfs_client - Plugin to monitor NFS client traffic

=head1 NOTES

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.
