 # Alerting
-* Glass alerts check once a minute for subnet utilization and every 5 seconds for lease-rate alerts
-  * Shared Network Utilization % Thresholds (Warning & Critical) (Default 0 and 95)
-  * Leases per minute rate (Default 50)
-  * 0 values = Off
+* **Realtime Alerting** One of our biggest high value returns on this project was creating something that can keep us on top of any sort of outage issues. 
+  * "Is our server writing leases even though the process is alive?"
+  * "Is any our shared networks filling up?"
+* **Shared Subnet Utilization Alerting** (Checked once a minute)
+    * Customize thresholds
+      * Default 80 (Warning)
+      * Default 95 (Critical)
+* **Leases Per Minute** (Checked once every 5 seconds) - If your disk fills up - or your SAN is unavailable - alerting your team on absolutely zero activity on your production server can allow you to be on the 8-ball. This is a step-above process alerting because you can have the dhcp server process running and no leases being written.
+  * **Default**: 50
+  * Glass keeps track of a rolling average of leases being written on the minute, the counter can be seen realtime on the dashboard
+* 0 value in **Glass Settings** or in your **glass_config.json** will turn the alerting functionality **OFF**
