Hi,

I have a ticketing system that is integrated with Alert Manager. When an issue is triggered and an alert is created, it is routed via webhook to my system. However, the but fingerprint is not unique for each issue; it is unique per alert.

I need to create a unique fingerprint per ticket when an alert fired, and when it is resolved, the resolution must refer to the same fingerprint.

How can I resolve this issue?

Yes that's correct. Fingerprints are unique per alert.

Look at how this works for Jira https://github.com/prometheus/alertmanager/blob/main/notify/jira/jira.go#L90-L107.
