Example:
|
|
|
|
perl centreon_plugins.pl --plugin=cloud::azure::management::insightsmetrics::plugin --custommode=api --mode=memory
|
|

|
|
=item B<--workspace-id>
|
|
(Mandatory)
|
|
Specify the Azure Log Analytics Workspace ID.
|
|
|
|
=item B<--filter-computer>
|
|
|
|
Filter on a specific Azure "computer" name.
|
|
Example: --filter-name='azure-vm1'
|
|
|
|
=item B<--filter-resourceid>
|
|
|
|
Filter on a specific Azure "computer" based on the full resource ID.
|
|
Example: --filter-resourceid='/subscriptions/1234abcd-5678-defg-9012-3456789abcde/resourcegroups/my_resourcegroup/providers/microsoft.compute/virtualmachines/azure-vm1'
|
