Taking my managed container image registry service as an example.
- The only critical alert that can actually page people is if the blackbox test fails. Every 30 seconds, it downloads a test image and if the contents don't match the expectation, an alert is raised (with some delay).
- Warning alerts are mostly for any errors being returned from background tasks, but these are only monitored during business hours.
- perfect_wave 2y agoi dont see how that is separated from the underlying infra. If the network/server/some dependency goes down, the blackbox test will fail and you'll get paged.
- silisili 2y agoYou can test for this. For example, we had routines that were called on repeated HTTP failures that would then get 5 or so of the top US websites. If those fail too, it moves from an application error to an infra one.
