Hi Dimitri,
After checking everything, I created a new job with the same configuration only I changed the AggregateAlerts - True.
From then, both the jobs are running without any errors. And suddenly 139 alerts triggered in the first job for which I asked the above query. Also, I got the mails as expected.
After analysis, I deleted the new created job and kept the old one. Now, it is working fine but not working as expected time intervals(2 min).
Job is running after 2 min, but the alert is generated in 4th or 5th occurrence of the running job. Not sure why?
Please let me know your views on this.
Thanks,
Nidhi
