Check virtual machine resources disk IO metrics.
|
|
|
|
Example:
|
|
|
|
Using resource name :
|
|
|
|
perl centreon_plugins.pl --plugin=cloud::azure::compute::virtualmachine::plugin --custommode=azcli --mode=diskio
|
|
--resource=MYSQLINSTANCE --resource-group=MYHOSTGROUP --aggregation='total' --aggregation='average'
|
|
--critical-disk-write-bytes-total='10' --verbose
|
|
|
|
Using resource id :
|
|
|
|
perl centreon_plugins.pl --plugin=cloud::azure::compute::virtualmachine::plugin --custommode=azcli --mode=diskio
|
|
--resource='/subscriptions/xxx/resourceGroups/xxx/providers/Microsoft.Compute/virtualMachines/xxx'
|
|
--aggregation='total' --aggregation='average' --critical-disk-write-bytes-total='10' --verbose
|
|
|
|
Default aggregation: 'total', 'average' / All aggregations 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 metrics (Can be: 'Disk Read Bytes', 'Disk Write Bytes',
|
|
'Disk Read Operations/Sec', 'Disk Write Operations/Sec') (Can be a regexp).
|
|
|
|
=item B<--warning-$metric$-$aggregation$>
|
|
|
|
Thresholds warning ($metric$ can be: 'disk-read-bytes', 'disk-write-bytes', 'disk-read-operations-sec',
|
|
'disk-write-operations-sec', $aggregation$ can be: 'minimum', 'maximum', 'average', 'total').
|
|
|
|
=item B<--critical-$metric$-$aggregation$>
|
|
|
|
Thresholds critical ($metric$ can be: 'disk-read-bytes', 'disk-write-bytes', 'disk-read-operations-sec',
|
|
'disk-write-operations-sec', $aggregation$ can be: 'minimum', 'maximum', 'average', 'total').
|
|
|
|
=item B<--per-sec>
|
|
|

Change the data to be unit/sec.
