Fields

DisconnectFailedPreconditionTotal

Total RpcException raised with StatusCode.FailedPrecondition from any RPC method. Tagged by method name. Increments unconditionally — even when the ownership-forward path catches the exception.

public static readonly Counter<long> DisconnectFailedPreconditionTotal

Field Value

Counter<long>

DisconnectForwardedTotal

Total RPC calls forwarded to the owning replica via Dapr service invocation. Tagged by method name. Stays at 0 when OWNERSHIP_MISS_FORWARD_THRESHOLD is 0 (default).

public static readonly Counter<long> DisconnectForwardedTotal

Field Value

Counter<long>

DisconnectOwnershipMissTotal

Total cross-instance ownership misses. Tagged by reason (not_owned when the local replica is not the owner, lapsed when the owner has dropped from knownInstances past INSTANCE_STALE_THRESHOLD_SECONDS). Paired with DisconnectForwardedTotal to measure how many misses were successfully forwarded to the owner replica.
