Struct SupervisorMetrics 

pub struct SupervisorMetrics {
    pub restarts_total: AtomicU64,
    pub active_services: AtomicU64,
    pub spawned_total: AtomicU64,
    pub terminated_total: AtomicU64,
    pub circuit_breaker_trips: AtomicU64,
}

Atomic counters for supervisor-level metrics.

When the prometheus feature is enabled, these are mirrored into the crate-local prometheus registry available via the prometheus submodule. Without the feature this is the only metrics surface.

Fields

restarts_total: AtomicU64

Total service restarts (clean-exit + on-failure cycles).

active_services: AtomicU64

Currently-alive services (not yet in Terminated).

spawned_total: AtomicU64

Total services ever spawned, including restarts.

terminated_total: AtomicU64

Total services that have reached Terminated.

circuit_breaker_trips: AtomicU64

Total times any service’s circuit breaker has tripped.
