This alert is to trigger actions every time any interface crosses the 500GB threshold of received traffic.
For example, at 12 on Monday if there 0 GB of received traffic, and by 5 PM 500GB of traffic has been received the first alert would be triggered. Then between 5 PM and 10 PM if another 500GB is received the second alert would be triggered and so on.
These are the steps to make the alert functional:
1. Create new Interface Custom Property called LastTriggeredInTotalBytes using Format - Floating Point Number
2. Import attached alert CustomAlert.xml
3. Rename the Alert name as required.
Similar alert could be created also for transmitted traffic. Alert can also be customized to only monitor specific interfaces for this condition.
Thanks to Jiri Psota for creating this alert.
