| Signal | Metric |
|---|---|
| Latency | histogram_quantile(0.99, ...) |
| Traffic | sum(rate(requests_total[5m])) |
| Errors | rate(errors_total[5m]) |
| Saturation | node_memory_MemAvailable_bytes |
| Symptom | Root Cause | Solution |
|---|---|---|
| No data | Scrape failing | Check targets page |
| Alert not firing | PromQL error | Test in UI |
| High cardinality | Too many labels | Reduce labels |
| Slow queries | Too much data | Add aggregation |
