Regarding how to configure alarms through VNFDs for the auto-scaling use case, follow the [auto-scaling documentation](#autoscaling)
##### Alarm Notification Enhancement
Whenever a threshold is crossed, POL sends 'alarm' to alarm server and when the threshold is lower than the threshold, POL sends 'ok' to alarm server for every evaluation cycle.Republishing the alarm/ok inspite of no status change floods with notification messages.

###### Enabling the alarm notification enhancement
- Configure POL to enable the alarm notification enhancement by changing the `pol.yaml`:

#### Experimental functionality
An optional 'OSM ELK' stack is available to allow for events visualization, consisting of the following tools:
