trace_methods configuration option to specify additional methods to instrument.
You can match methods via wildcards in the package, class or method name, by their modifier (like public),
by a particular annotation, and more.
Because you don’t need to modify your source code, this makes it possible to monitor code in 3rd party libraries.
Be careful, it’s easy to overuse
trace_methods by matching too many methods—hurting both runtime and startup performance.
Use in conjunction with
span_min_duration when setting for entire packages
in order to avoid having too many spans in the APM app.
For more information, and examples, see the
trace_methods configuration reference.
