Thanks in advance.
We have scenario that we need to send alerts multiple times .
1. Lagging E.g Lets put Threshold time : 1 Hour
20/02 10:00 AM NZT : Lagging encountered after 1 Hour threshold -> Alert#1 via email with subject : Total lag time
20/02 11:00 AM NZT : Lagging still occur -> Alert#2 via email with subject : Total lag time 2 hour (Accumulated lagging hour) + Create Incidents in ServiceNow
20/02 13:00 PM NZT : Lagging encountered after 1 Hour threshold -> Alert#3 via email with subject : Total lag time
20/02 14:00 PM NZT : Lagging encountered after 1 Hour threshold -> Alert#4 via email with subject : Total lag time ---Got fixed
