=head1 NAME
df - Plugin to monitor disk usage (measuring byte usage in percent)
=head1 CONFIGURATION
This shows the default configuration
[df*]
env.df /usr/sbin/df
env.warning 92
env.critical 98
A device specific warning/critical level is also supported. Append
the munin label (shown in the plugin display page) and append _warning
or _critical respectively to get the (environment variable) name.
To limit the monitored filesystems, configure the "only" environment variable.
For example, to only monitor /, one would add to plugin-conf.d:
[df*]
env.only /
=back
=head1 AUTHOR
Unknown author
=head1 LICENSE
GPLv2
