=head1 NAME

zimbra_ - Plugin to monitor all sorts of Zimbra statistics

=head1 APPLICABLE SYSTEMS

Zimbra 5+ with zmstat statistics enabled.

Text::CSV_XS (perl-Text-CSV_XS from EPEL, for example)

=head1 CONFIGURATION

Add this to the relevant munin-node config file:

 [zimbra*]
 group zimbra

The following environment variables are used by this plugin:

=over 4

=item csvpath

Path to zmstat csv files (default /opt/zimbra/zmstat)

=back

=head1 BUGS/GOTCHAS

Only reads latest value from the csv, which may be a "last 30 seconds"
or "last minute" value, so not a representative "last five minutes" value.
The original Zimbra stat charts often use a moving average of some sort.
