Alert grouping

Combining many related signals, such as the same error repeated, into one problem so a responder sees it once.

In Pagerless

Errors with the same type, top stack frames and route share a fingerprint and become one problem.

Fingerprint
A stable key computed from an error's type, stack and route, used to decide which events belong to the same problem.
Alert fatigue
When responders receive so many alerts, many not actionable, that they start ignoring or muting them and miss the ones that matter.
