Monitor for User Impact, Not Dashboard Vanity
Great monitoring answers one question fast: are users currently affected?
Essential Metrics by Layer
| Layer | Metric | Why It Matters |
|---|---|---|
| Edge | Request rate + blocked requests | Detect traffic anomalies |
| App | p95 latency | User-perceived speed |
| App | 5xx error rate | Reliability signal |
| Compute | CPU saturation | Performance bottleneck detection |
| Memory | Utilization + OOM events | Crash prevention |
| Storage | IOPS and latency | DB/API responsiveness |
Alerting Rules That Work
- Trigger alerts on sustained breaches, not single blips.
- Add route-level alerting for high-value endpoints.
- Attach runbook links in every page notification.
Where Orihost Fits Naturally
Regardless of stack, hosted teams need stable infrastructure and clear scaling options. Orihost hosting plans make it easier to react to growth before reliability degrades.
