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(context: IContext, 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(context: IContext, 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(context: IContext, 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.
