Class Instrumentation

java.lang.Object

com.atlassian.jira.instrumentation.Instrumentation

All Implemented Interfaces:

Startable

public class Instrumentation
extends Object
implements Startable

A static singleton style class that exposes DefaultInstrumentRegistry functionality. You can instrument JIRA code something like this

  OpTimer timer = Instrumentation.pullTimer("some.operation");
  try {
      ... some operation in JIRA
      ...
  } finally {
      timer.end();
  }
 

This will cause invocation count and time taken information to be stored away in a OpCounter called "some.operation". Simple.

You do not have to worry about recording this data, it will be done for you later.

Since:

v5.0
