Check Azure Application Gateway backend hosts health statistics.

Example:
|
||||
|
||||
Using resource name :
|
||||
|
||||
perl centreon_plugins.pl --plugin=cloud::azure::network::appgateway::plugin --mode=backend-health --custommode=api
|
||||
--resource=<appgateway_id> --resource-group=<resourcegroup_id> --aggregation='average'
|

--warning-unhealthy-host-count='1' --critical-unhealthy-host-count='2'
|
||||
|
||||
Using resource id :
|
||||
|
||||
perl centreon_plugins.pl --plugin=cloud::azure::network::appgateway::plugin --mode=backend-health --custommode=api
|
||||
--resource='/subscriptions/<subscription_id>/resourceGroups/<resourcegroup_id>/providers/Microsoft.Network/applicationGateways/<appgateway_id>'
|
||||
--aggregation='average' --warning-unhealthy-host-count='1' --critical-unhealthy-host-count='2'
|

Default aggregation: 'average' / 'total', 'minimum' and 'maximum' are valid.
