Check mysql queries metrics.

Example:

perl centreon_plugins.pl --plugin=cloud::google::gcp::cloudsql::mysql::plugin
--mode=diskio --dimension-value=mydatabaseid --filter-metric='queries'
--aggregation='average' --verbose

Default aggregation: 'average' / All aggregations are valid.

=over 8

=item B<--dimension-name>

Set dimension name (Default: 'resource.labels.database_id'). Can be: 'resources.labels.region'.

=item B<--dimension-operator>

Set dimension operator (Default: 'equals'. Can also be: 'regexp', 'starts').

=item B<--dimension-value>

Set dimension value (Required).

=item B<--filter-metric>

Filter metrics (Can be: 'database/mysql/questions', 'database/mysql/queries') (Can be a regexp).

=item B<--timeframe>

Set timeframe in seconds (i.e. 3600 to check last hour).

=item B<--aggregation>

Set monitor aggregation (Can be multiple, Can be: 'minimum', 'maximum', 'average', 'total').

=item B<--warning-*> B<--critical-*>

Thresholds (Can be: 'queries', 'questions').

=item B<--per-second>

Change the data to be unit/sec.
