Opsgenie + AWS SNS + Slack integration issue

Dmitry Petriev August 14, 2023

Hello everyone, 


Recently I faced a problem with notifications in Slack. I have an AWS SNS topic which fetches alerts from alertmanager, and this couple works well because I can get an alert in OpsGenie. And that alert also comes to the Slack channel. But, if alertmanager fires a new second alert before the first one closes, that alert will not occur in Opsgenie and Slack. What could be the reason for such behaviour?

Hi @Dmitry Petriev ,

It sounds like the alerts are being deduplicated. This is a feature that is designed to help prevent alert fatigue. 

When a new payload is received with the same alias as an existing, open alert, instead of creating another alert, the open alert's count is increased by one.  

If you want to prevent this, you would need to either be sure to close alerts before new ones arrive, or edit the dynamic fields in the alias, so that a unique value is generated for each alert.
