Exporter
Interface for exporting telemetry signals to external systems.
Exporters are responsible for transmitting log, metric, and span batches to backends like OTLP collectors, console output, or in-memory stores.
The signal type is carried on the Signal::$type discriminator.
Methods
- export() : bool
- Export a signal batch.
- shutdown() : void
- Shutdown the exporter and any owned transports.
Methods
export()
Export a signal batch.
public
export(Signals $signal) : bool
Implementations dispatch on Signal::$type via match.
Parameters
- $signal : Signals
Return values
bool —True on success, false on failure
shutdown()
Shutdown the exporter and any owned transports.
public
shutdown() : void
Implementations MUST be idempotent and MUST NOT throw - runtime errors are routed through the configured error handler instead.
