Alert is overwritten when triggering a new event with the same dedup key

[dillu24]

I am trying to create an event, and then create another event with the same dedup. I expect that there will be 2 alerts in the same incident, however there is only 1 (new summary), which means that the alert is overwritten.

This is my code:

from pdpyras import EventsAPISession


class PagerDutyApi:
    def __init__(self, integration_key: str) -> None:
        self._session = EventsAPISession(integration_key)

        # Returns the dedup key
        dedup = self._session.trigger(summary='test summary', source='val1', severity='info')
        self._session.trigger(summary='new summary', source='val1', severity='info', dedup_key=dedup)


PagerDutyApi('Dummy-Integration-Key')

I concur, having the same experience here.

Hi @dillu24 and @amandeep-r ,

This is expected behavior; two events of the same dedup key will always be merged into a single alert and shown as events in the alert's history log.

Be that as it may, PagerDuty's event intelligence add-on has some nifty features for automatically grouping alerts into single incidents based on other criteria such as event message content and time received.
