Check Azure Virtual Machine Scale Sets Traffic In and Out.

Example:

Using resource name:

perl centreon_plugins.pl --plugin=cloud::azure::compute::vmscalesets::plugin --mode=traffic --custommode=api
--resource=<vmss_id> --resource-group=<resourcegroup_id> --warning-traffic-out=10000 --critical-traffic-in=15000

Using resource ID:

perl centreon_plugins.pl --plugin=cloud::azure::vmscalesets::plugin --mode=traffic --custommode=api
--resource='/subscriptions/<subscription_id>/resourceGroups/<resourcegroup_id>/providers/Microsoft.Compute/virtualMachineScaleSets/<vmss_id>' 
--warning-traffic-out=10000 --critical-traffic-in=15000

=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<--warning-*>

Warning threshold where '*' can be: 'traffic-out', 'traffic-in'.


=item B<--critical-*>

Critical threshold where '*' can be: 'traffic-out', 'traffic-in'.

=item B<--per-sec>

Change the data to be unit/sec.
