delegated devices is driven by Mimir telemetry,
not by deployment mode. The health-status agent does not receive Metal Managed or
Metal Self-Managed context; it queries Mimir for device health metrics and applies
the same missing-data behaviour for every device:
- Metric value
0:health_status=healthy - Metric value greater than
0:health_status=degraded - Missing, negative, or invalid metric:
health_status=unknown
Deployment Behaviour
Operator Notes
For a Metal Managed device,delegated means Fleet Manager lifecycle agents stand
down, but health can still update while read-only BMC telemetry is present in Mimir.
For a Metal Self-Managed device, health_status=unknown is expected while the device
is delegated. Fleet Manager has no BMC visibility until the device is reclaimed, so
absence from the Mimir query is not by itself a health-agent fault. If the device still
appears in the Mimir query, Fleet Manager will report that metric because the health
agent has no deployment-mode override.
If a delegated Metal Managed device unexpectedly reports unknown, first check
whether the device appears in the configured Mimir query and whether the health metric
contains the configured device label.
