Shwetha G S commented on ATLAS-1116:
------------------------------------
Exposes annotations @Monitored and @Loggable on methods.
@Monitored records how many times that method is called and total execution
time in that method. These metrics are aggregated at API level and are recorded
in metric.log(one log line per API call)
@Loggable logs at the beginning of the method and ending of the method with
arguments and return values
These annotations are injected using aspectj plugin at compile time, there is
no runtime overhead except for the method invocation
Example metrics collected:
