Hey @arundharmabe
This looks like a copy of the incident_metric database view. You're basically pulling all the metric instances that have been created for incident, but you're always going to have some "duplicates".
That's because what it's actually showing is the record from each time a metric has been created, and it's expected that many metrics would trigger more than once. For instance, if it's configured for assignment group you'd have multiple rows for a single incident, representing each time the assignment group was changed.
It might be less confusing if you pull in the Definition column, you could filter out what you don't want or at least show that the entries represent different definitions.
