Most weeks I send one short letter about the alerting layer: a failure mode I hit, why the stack stayed green through it, and the change that would have caught it. No roundups, no tool news, no "10 best Grafana plugins".
What you get
- One failure mode per letter, stated plainly enough that you can go check your own stack against it the same afternoon.
- The query, rule or config that fixes it, not a gesture at one.
- Generic by design. Invented hostnames, invented service names, numbers chosen to show a shape rather than report one. Nothing here comes from anyone’s production but the shape of the problem is real.
Recent subjects: alert payloads that report active: [] while the metrics pipeline is down, per-path SLOs that site averages compress away, no_data handling nobody configured.
Read the archive first if you'd rather see the shape of it before handing over an address.
If you’d rather I just look at yours
The letters come out of the same work as the free alert audit: you send me your stack, I come back with the handful of alerts that actually matter and one thing you almost certainly have wrong.
