ITracer

Interface for tracer components that capture operation traces.

Description

The ITracer interface is used to create tracer component that capture operation traces.

Instance methods

beginTrace

Begings recording an operation trace

beginTrace(correlationId: string, component: string, operation: string): TraceTiming

  • correlationId: string - (optional) transaction id to trace execution through a call chain.
  • component: string - name of the called component
  • operation: string - name of the executed operation.
  • return: TraceTiming - a trace timing object.

failure

Records an operation failure with its name, duration and error.

failure(correlationId: string, component: string, operation: string, error: Error, duration: number): void

  • correlationId: string - (optional) transaction id to trace execution through call chain.
  • component: string - a name of called component
  • operation: string - a name of the executed operation.
  • error: Error - an error object associated with this trace.
  • duration: number - execution duration in milliseconds.

trace

Records an operation trace with its name and duration

trace(correlationId: string, component: string, operation: string, duration: number): void

  • correlationId: string - (optional) transaction id to trace execution through a call chain.
  • component: string - name of the called component
  • operation: string - name of the executed operation.
  • duration: number - execution duration in milliseconds.
