Tracer Plugin - Logs do not show exceptions/stacktraces

[davidjgonzalez]

@chetanmeh been meaning to log for this some time; it doesnt appear exception stacktraces are included in tracer logs.

For example...

The actual log statement for the above reads log.info('Error during children processing of {}', path, e); and the error.log has the NPE exception and the stack tracer. Looking at the Tracer response, i dont see that info being sent.

I am setting caller=true on all tracersets (including that package) which includes the call stack, but not the exception stacktrace. Am i missing something?
