getTraceContext

public <T> io.opentelemetry.context.Context getTraceContext(T carrier,
                                                            io.opentelemetry.context.propagation.TextMapGetter<T> textMapGetter)

Specified by:

getTraceContext in interface TraceContextHandler

getTraceContext

public Map<String,String> getTraceContext(String transactionId)

Get the trace context information for a given transaction id. This returns a Map with at least one entry with key TransactionStore.TRACE_TRANSACTION_ID and transactionId as value. The other entries in the map depends on the propagator used. For W3C Trace Context Propagator, it can contain entries for `traceparent` and optionally `tracestate`.

Parameters:

transactionId - Local transaction id

Returns:

Map

getTraceContext

public Map<String,String> getTraceContext(String transactionId,
                                          org.mule.runtime.api.component.location.ComponentLocation componentLocation)

Get the trace context information for a given transaction id. This returns a Map with at least one entry with key TransactionStore.TRACE_TRANSACTION_ID and transactionId as value. The other entries in the map depends on the propagator used.

For W3C Trace Context Propagator, it can contain entries for `traceparent` and optionally `tracestate`.

Parameters:

transactionId - Local transaction id

componentLocation - ComponentLocation to get context for

Returns:

Map

injectTraceContext

public <T> void injectTraceContext(T carrier,
                                   io.opentelemetry.context.propagation.TextMapSetter<T> textMapSetter)

Specified by:

injectTraceContext in interface TraceContextHandler

getTransactionStore

invalidate

public void invalidate()

addProcessorSpan

public void addProcessorSpan(TraceComponent traceComponent,
                             String rootContainerName)

Creates a Span for given TraceComponent and adds it to the TraceComponent.getTransactionId() transaction.

Parameters:

traceComponent - TraceComponent

rootContainerName - String name of the container such as flow that holds this component

endProcessorSpan
