| <div class="block">An annotation for marking a method, constructor, or class as timed. |
| The underlying <a href="../../../../../org/eclipse/microprofile/metrics/Timer.html" title="interface in org.eclipse.microprofile.metrics"><code>Timer</code></a> |
| metric aggregates timing durations and provides duration statistics, |
| plus throughput statistics. There is a lightweight alternative |
| <a href="../../../../../org/eclipse/microprofile/metrics/SimpleTimer.html" title="interface in org.eclipse.microprofile.metrics"><code>SimpleTimer</code></a> |
| (@<a href="../../../../../org/eclipse/microprofile/metrics/annotation/SimplyTimed.html" title="annotation in org.eclipse.microprofile.metrics.annotation"><code>SimplyTimed</code></a>) that only tracks elapsed time duration and |
| count. The metric will be registered in the application MetricRegistry. |
| <p> |
| Given a method annotated with @Timed like this: |
| </p> |
| <pre><code> |
| @Timed(name = "fancyName") |
| public String fancyName(String name) { |
| return "Sir Captain " + name; |
| } |
| </code></pre> |
| A timer with the fully qualified class name + <code>fancyName</code> will be created and each time the |
| <code>#fancyName(String)</code> method is invoked, the method's execution will be timed. |
| |
| <p> |
| Given a class annotated with @Timed like this: |
| </p> |
| <pre><code> |
| @Timed |
| public class TimedBean { |
| public void timedMethod1() {} |
| public void timedMethod2() {} |
| } |
| </code></pre> |
| A timer for the defining class will be created for each of the constructors/methods. |
| Each time a constructor/method is invoked, the execution will be timed with the respective timer. |
| |
| This annotation will throw an IllegalStateException if the constructor/method is invoked, but the metric no |
| longer exists in the MetricRegistry.</div> |
