**TL;DR:** Default alerts either spam or miss the incident. Set thresholds from your baseline, route by severity, and use maintenance windows. For each firing alert ask: did a human need to act? Confirm Check the metric baseline first.

## The error

```text
alert fatigue (ignored pages) or silent incidents (no alert fired).
```

## The fix

1. Thresholds from baseline: e.g. connections above 80% of tier cap sustained 5 minutes, disk above 75%, replication lag above your SLA.

2. Route by severity: page for data-loss risks (replication, backup failures), notify chat for early warnings (disk 75%, slow query uptick).

3. Maintenance windows during deploys and index builds so planned work does not page.

4. Every alert needs a runbook link: what to check first. An alert nobody knows how to answer is noise.
