Struct SupervisorMetrics 

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

Atomic counters for supervisor-level Prometheus-compatible metrics.

These map directly to the metrics specified in the architecture doc:

  • janus_supervisor_restarts_total
  • janus_supervisor_active_services
  • janus_supervisor_spawned_total

Fields§

§restarts_total: AtomicU64

Total number of service restarts across all services.

§active_services: AtomicU64

Number of services currently in a non-terminal phase.

§spawned_total: AtomicU64

Total number of services ever spawned (including restarts).

§terminated_total: AtomicU64

Total number of services that have terminated.

§circuit_breaker_trips: AtomicU64

Total number of circuit breaker trips.
