I have AWS Cloudwatch hooked up with PagerDuty. Whenever an alert goes out, it goes to PagerDuty, which then sends us a message in Slack. The problem is, this is what it shows in the chat:
Triggered #3362: Maximum CPUUtilization of 53.6 GreaterThanOrEqualToThreshold 50.0 for InstanceId i-xxxxxxxxx
That's about as useful as a rock. There's no way I could interpret the instance ID, nor should I have to read all that stuff at a glance and figure out what's wrong.
The question is, how do I change the incident name that gets generated on PagerDuty, or is this something that can be done in Cloudwatch, or am I hosed?
