=head1 DESCRIPTION

This script collects interesting monitoring data from the ElasticSearch cluster and maps
that data directly into Graphite.  If ElasticSearch changes the names of data, those changes
will be reflected in the metric path immediately.

=item B<help>

Print this message and exit

=item B<manual>

Print this message and exit

=item B<carbon-base>

The prefix to use for metrics sent to carbon.  The default is "general.es".  Please note, the host name
of the ElasticSearch node will be appended, followed by the metric name.

=item B<carbon-server>

Send stats to the carbon server specified.  This automatically forces --format=graphite
and does not produce stats on STDOUT

=item B<carbon-port>

Use this port for the carbon server, useless without --carbon-server

=item B<ignore>
