Metrics reference
Prometheus-format metrics are available at /q/metrics alongside Quarkus runtime metrics.
| Metric | Type | Unit | Meaning |
|---|---|---|---|
| donkeyfleet.capacity.unprotected.provisioned | Gauge | bytes | Provisioned capacity of observed unprotected candidates |
| donkeyfleet.capacity.unprotected.physical | Gauge | bytes | Physical data of observed unprotected candidates |
| donkeyfleet.capacity.orphaned.provisioned | Gauge | bytes | Provisioned capacity of observed orphan destinations |
| donkeyfleet.capacity.orphaned.physical | Gauge | bytes | Physical data of observed orphan destinations |
The endpoint emits Prometheus-normalized names, which can replace dots with underscores and append unit suffixes depending on registry conventions. Confirm the exposed series in your environment before writing alert rules.
Values are meaningful only after a complete observation. Pair graphs with the last reconcile outcome so a retained value is not mistaken for a fresh partial calculation.
Recommended initial alerts:
- unprotected physical bytes above the agreed backup-risk threshold;
- orphaned provisioned bytes above zero for longer than the review window;
- readiness failure;
- last successful complete observation older than the operational objective, using logs or an external check until a custom reconcile-age metric is added.
