Quite possibly *none* of your sub-matchers are matching, and it's falling
back to the default receiver 'middleEarth-alerts-prod-critical' which is at
the same level as routes:
route:
routes:
- matchers: [ owner = middleEarth ]
receiver: 'middleEarth-alerts'
routes:
- matchers: [ alertname = MordorThreatens ]
* receiver: 'middleEarth-alerts-prod-critical' << this is used
if *none* of the routes below match*
routes: ...
But without seeing your actual alert labels and conditions I can't give any
more help.
There is an alert route testing tool you can use online, and you can paste
in your *real* labels and matchers:
