Check Azure SQL Elastic Pool Storage metrics.
|
|
|
|
Example:
|
|
|
|
Using resource name :
|
|
|
|
perl centreon_plugins.pl --plugin=cloud::azure::database::elasticpool::plugin --custommode=azcli --mode=storage
|
|
--resource=<sqlserver>/elasticpools/<elasticpool> --resource-group=<resourcegroup> --aggregation='average'
|
|
--allocated-data-storage-percent='90' --verbose
|
|
|
|
Using resource id :
|
|
|
|
perl centreon_plugins.pl --plugin=cloud::azure::compute::virtualmachine::plugin --custommode=azcli --mode=sessions
|
|
--resource='/subscriptions/xxx/resourceGroups/xxx/providers/Microsoft.Sql/servers/xxx/elasticpools/xxx'
|
|
--aggregation='average' --allocated-data-storage-percent='90' --verbose
|
|
|
|
Default aggregation: 'average' / 'minimum' and 'maximum' are valid.
|
|
|
|
=over 8
|
|
|
|
=item B<--resource>
|
|
|
|
Set resource name or id (Required).
|
|
|
|
=item B<--resource-group>
|
|
|
|
Set resource group (Required if resource's name is used).
|
|
|
|
=item B<--filter-metric>
|
|
|
|
Filter on specific metrics. The Azure format must be used, for example: 'allocated_data_storage_percent'
|
|
(Can be a regexp).
|
|
|
|
=item B<--warning-*>
|
|
|
|
Warning threshold where * can be: 'allocated-data-storage', allocated-data-storage-percent',
|
|
'storage-percent', 'storage-used'.
|
|
|
|
=item B<--critical-*>
|
|
|
|
Critical threshold where * can be: 'allocated-data-storage', allocated-data-storage-percent',
|
|
'storage-percent', 'storage-used'.
|
