=head1 MODE

Check computation engine statistics.

Example:

perl centreon_plugins.pl --plugin=apps::centreon::map::jmx::plugin --custommode=jolokia
--url=http://10.30.2.22:8080/jolokia-war --mode=engine-stats

=over 8

=item B<--filter-counters>

Only display some counters (regexp can be used).
(Example: --filter-counters='computation')

=item B<--warning-*>

Threshold warning.
Can be: ''drilldown-candidates-queue', 'cutback-computation-rate',
'minimal-computation-rate', 'recursive-computation-rate'.

=item B<--critical-*>

Threshold critical.
Can be: ''drilldown-candidates-queue', 'cutback-computation-rate',
'minimal-computation-rate', 'recursive-computation-rate'.
