conduit::metrics Namespace Reference

Functions
std::shared_ptr< prom::Scope > &	scope ()
	The shared conduit scope; applies the conduit_ prefix to every metric.
prom::Counter &	events_published ()
	Envelopes that entered the dispatch pipeline (one per Bus::publish).
prom::Counter &	events_dropped ()
	Envelopes dropped before listener fan-out (a middleware before_dispatch returned false, or a routing conflict).
prom::Counter &	listener_invocations ()
	Listener handler calls during fan-out (counts every matched listener, summed over all delivered envelopes).
prom::Counter &	listener_errors ()
	Listener handlers that threw during fan-out.
prom::Counter &	transport_errors ()
	Transport-level inbound failures, selected by the transport label ("redis", "amqp", "zmq", "mqtt", "nats", …).
prom::Gauge &	listeners ()
	Live listener subscriptions across all buses in the process.
prom::Histogram &	dispatch_seconds ()
	Wall-clock seconds from publish to the end of the synchronous dispatch pipeline.

Function Documentation

dispatch_seconds()

prom::Histogram & conduit::metrics::dispatch_seconds ( )

inline

Wall-clock seconds from publish to the end of the synchronous dispatch pipeline.

For asynchronous transports (Queue / ThreadPool) this measures the enqueue + routing portion, not the listener execution that runs off-thread.

events_dropped()

prom::Counter & conduit::metrics::events_dropped ( )

inline

Envelopes dropped before listener fan-out (a middleware before_dispatch returned false, or a routing conflict).

events_published()

prom::Counter & conduit::metrics::events_published ( )

inline

Envelopes that entered the dispatch pipeline (one per Bus::publish).

listener_errors()

prom::Counter & conduit::metrics::listener_errors ( )

inline

Listener handlers that threw during fan-out.

listener_invocations()

prom::Counter & conduit::metrics::listener_invocations ( )

inline

Listener handler calls during fan-out (counts every matched listener, summed over all delivered envelopes).

listeners()

prom::Gauge & conduit::metrics::listeners ( )

inline

Live listener subscriptions across all buses in the process.

scope()

std::shared_ptr< prom::Scope > & conduit::metrics::scope ( )

inline

The shared conduit scope; applies the conduit_ prefix to every metric.

transport_errors()

prom::Counter & conduit::metrics::transport_errors ( )

inline

Transport-level inbound failures, selected by the transport label ("redis", "amqp", "zmq", "mqtt", "nats", …).
