Golden signals
Check a service’s latency, traffic, errors and saturation against their thresholds in one place.
Reliability & managed IT servicesHow it's worked out
- Each signal ÷ its threshold; near = over 85% of threshold
- Thresholds from your SLOs and capacity tests
NoteSaturation is the early warning: it rises before latency and errors do.
