Alert events with same alias but different priority

[Daniel Prado Martinez]

In a shot: Does alias uniqueness work systemwide or per priority level?

Explanation: several alert events received from an integration containing the same alias will be assigned to the same alert in OpsGenie. This helps to provide alert de-duplication according to the documentation.

What happens when these alert events have different priorities? Are they assigned to the same alert in OpsGenie?

If this is the case, what is the priority of this alert? First received? Highest received?

Thanks in advance!

Hi @Daniel Prado Martinez ,

When an alert is deduplicated by another alert of higher priority, the deduplicated alert’s priority is increased and its notification flow is restarted. But deduplication cannot downgrade an alert's priority - only increase it.

[Daniel Prado Martinez]

This means we would receive a second notification when the alert's priority is increased, correct?

Yes, that's correct. Here's an example of an alert being deduplicated wit ha higher priority:

Hi @Nick H , 

for me it's not working.

I have an alert definitions prometheus like

- alert: Alert
  annotations:
  description: Alert description
  summary: Alert summary
  expr: promql query
  for: 5m
  labels:
    priority: P2

this alert come to OpsGenie with a P2, everything fine.

then I have the same alert, but after 15min should be a P1

- alert: Alert
  annotations:
  description: Alert description
  summary: Alert summary
  expr: promql query
  for: 15m
  labels:
    priority: P1

In OpsGenie, I never see any P1 for this alert, I can see the counter increase for the P2, but it never turns into a P1.

Any Idea ?

In my case, I noticed that when the alert priority increases from P3 to P2, for example, my automatic incident creation configuration is not triggered.
