SpanProcessor
Interface for processing spans when they start and end.
Implementations may collect spans for batching, export them immediately, or perform other processing like filtering or sampling.
Methods
- exporter() : SpanExporter
- Get the exporter used by this processor.
- flush() : bool
- Export all pending spans and return success status.
- onEnd() : void
- Called when a span ends.
- onStart() : void
- Called when a span starts.
Methods
exporter()
Get the exporter used by this processor.
public
exporter() : SpanExporter
Return values
SpanExporterflush()
Export all pending spans and return success status.
public
flush() : bool
Forces immediate export of any buffered spans. Returns true if all spans were successfully exported.
Return values
boolonEnd()
Called when a span ends.
public
onEnd(Span $span) : void
This is invoked synchronously when the span completes. The span is fully populated at this point (end time, status, all attributes).
Parameters
- $span : Span
onStart()
Called when a span starts.
public
onStart(Span $span) : void
This is invoked synchronously when the span begins. Implementations should avoid blocking operations in this method.
Parameters
- $span : Span
