TraceTiming

Description

The TraceTiming class is used to create the timing object returned by ITracer.begin_trace to end the timing of and execution block and record the associated trace.

Constructors

Creates a new instance of the timing callback object.

TraceTiming(context: Optional[IContext], component: str, operation: str, tracer: ITracer = None)

• context: IContext - (optional) a context to trace execution through a call chain.
• component: str - an associated component name
• operation: str - an associated operation name
• tracer: ITracer - a callback that shall be called when endTiming is called.

Instance methods

end_failure

Ends timing of a failed block, calculates elapsed time and records the associated trace.

end_failure(error: Exception)

• error: Exception - an error object associated with this trace.

end_trace

Ends timing of an execution block, calculates the elapsed time and records the associated trace.

end_trace()

Examples

timing = tracer.begin_trace("mymethod.exec_time");
try:
    ...
    timing.end_trace();
except Exceptions as err:
    timing.end_failure(err);
