|
|
|
|
Check that partitions for MySQL/MariaDB tables are correctly created.
|
|
The mode should be used with mysql plugin and dyn-mode option.

=over 8

|
|
|
=item B<--tablename>
|
|
|
|
This option is mandatory (can be multiple).
|
|
Example: centreon_storage.data_bin
|
|
|
|
=item B<--warning>
|
|
|
|
Threshold warning (number of retention forward days)
|
|
|
|
=item B<--critical>
|
|
|
|
Threshold critical (number of retention forward days)
|
|
|
|
=item B<--timezone>
|
|
|
|
Timezone use for partitioning (If not set, we use current server execution timezone)
