Hi everyone,

I’m using PagerDuty's Intelligent Alert Grouping / Unified Alert Grouping feature to reduce noise in alert notifications. I’ve configured alerts to be sent to Slack.

I understand that when the first alert in a group is triggered, it sends a Slack notification as expected.
But I have a question:

What happens when additional alerts are grouped into the same incident shortly after?

  • Will Slack send another notification when a second alert is grouped under the same incident? if no then 

  • How i will be notified on slack for other alerts from the same group?

Hey ​@sharmaji0007, how are you doing today? Here’s a breakdown of how it works:

When you’re using PagerDuty’s alert grouping, the first alert in a group will trigger a Slack notification as expected. However, when additional alerts are grouped into the same incident, Slack does not send a new notification for each one. The incident in PagerDuty will update with the new alert details, but you won’t see a new Slack message for every grouped alert.

If you want to see all the grouped alerts, you’ll need to open the incident in PagerDuty, where you can view the full alert timeline. Some teams set up custom webhooks or automations to post updates to Slack when new alerts are grouped, but that’s not the default setup.

Hope this helps clear things up! Let me know if I can help with anything else, and have a nice day!
