Do a not-so-dummy check.
Sequence and sequence index are stored in cache file. Use --statefile* options
to defined the way cache file is managed.
Examples:
perl centreon_plugin.pl --plugin=apps::centreon::local::plugin
--mode=not-so-dummy --status-sequence='ok,warning,ok,critical,critical,critical'
--output='Not so dummy service' --show-sequence --statefile-dir='/tmp'
perl centreon_plugin.pl --plugin=apps::centreon::local::plugin
--mode=not-so-dummy --status-sequence='up,down,down' --host
--output='Not so dummy host'
perl centreon_plugin.pl --plugin=apps::centreon::local::plugin
--mode=not-so-dummy --status-sequence='ok,ok,ok' --output='Not so dummy'
--metrics-count=5 --metrics-name='met.rics' --metrics-values-range='-15:42'

Comma separated sequence of statuses from which the mode should pick is
return code from.
(Example: --status-sequence='ok,critical,ok,ok' or --status-sequence='up,up,down' --host)
(Should be numeric value between 0 and 3, or string in ok, warning, critical, unknown, up, down).
=item B<--host>
Host statuses.
=item B<--restart-sequence>
Restart the sequence from the beginning (ie. reset the sequence).
=item B<--show-sequence>
Show the sequence is the output.
To be set if sequence is for host statuses.
=item B<--output>
Output to be returned.
=item B<--metrics-count>
Number of metrics to generate.
=item B<--metrics-name>
Name of the metrics (Default: 'metrics.number').
Metrics are suffixed by a number between 1 and metrics count.
=item B<--metrics-values-range>
Range of values from which metrics values can be picked (Default: '0:100').
=item B<--show-sequence>
Show the sequence is the output (in addition to the defined output).
=item B<--show-index>
Show the index as a metric (in addition to the defined metrics count).
=item B<--restart-sequence>
Restart the sequence from the beginning (ie. reset the sequence in cache file).
