+##### Alarm Notification Enhancement
+
+Whenever a threshold is crossed, POL sends 'alarm' to alarm server and when the metric is lower than the threshold, POL sends 'ok' to alarm server for every evaluation cycle. Republishing the alarm/ok in spite of no status change floods with notification messages.
+
+To overcome this issue, alarm notification enhancement will suppress sending repeated alarm/ok to alarm management server by comparing with the last status.
+
+In order to enable/disable the alarm notification enhancement in POL, change `pol.yaml` to set `enhanced_alarms` to `True`/`False`.
+
+```yaml
