When trying to set up a new PagerDuty Panther Alert Destination and sending off a test alert, the following issue occurs:
Panther tells me the test was successful, but PagerDuty didn’t create an alert on the service I connected with. The following error is displayed:
No Test Alert Received
To resolve this issue:
Double-check that your integration key is correct in Panther.
To verify the key in PagerDuty, go to Services > Your-integration-name > Gear Wheel.
Check that someone is listed as on-call for the service you've set up to receive the test alert.
If no one is on on-call when a PagerDuty alert is sent, then there won't be anyone available to receive it, and the test won't get delivered, as there's nobody to deliver it to.
