=item B<--elastic-path>
Set path to get Elasticsearch information (Default: '/_cluster/health?level=indices')
=item B<--filter-name>
Filter name (can be a regexp).
=item B<--filter-counters>
Only display some counters (regexp can be used).
Example: --filter-counters='^status$'
=item B<--warning-*>
Threshold warning.
Can be: 'active-primary-shards', 'active-shards'.
=item B<--critical-*>
Threshold critical.
Can be: 'active-primary-shards', 'active-shards'.
=item B<--warning-status>
Set warning threshold for status (Default: '%{status} =~ /yellow/i')
Can used special variables like: %{display}, %{status}.
=item B<--critical-status>
Set critical threshold for status (Default: '%{status} =~ /red/i').
Can used special variables like: %{display}, %{status}.
