Java EE Performance Measuring Interceptor.zip

# perceptor Java EE Performance Measuring Interceptor ## installation To gather statistics without automatically exposing them use the following dependency: ```xml <dependency> <groupId>com.airhacks</groupId> <artifactId>perceptor</artifactId> <version>[RECENT]</version> </dependency> ``` The statistics become available via injection: ```java import com.airhacks.interceptor.monitoring.control.InvocationMonitoring; public class MonitoringResource { @Inject InvocationMonitoring mes; } ``` The `perceptor-spy` dependency gathers statistics and exposes them via the `/monitoring/methods` endpoint: ```xml <dependency> <groupId>com.airhacks</groupId> <artifactId>perceptor-spy</artifactId> <version>[RECENT]</version> </dependency> ``` ## usage ```java import com.airhacks.interceptor.monitoring.boundary.PerformanceSensor; @Interceptors(PerformanceSensor.class) public class Invoker { public String slow() {} public String fast() {} } ``` ## statistics API all method invocations: `curl [THIN_WAR]/resources/monitoring/methods` all method invocations, sorted by timestamp: `curl [THIN_WAR]/resources/monitoring/methods/recent` slowest methods: `curl [THIN_WAR]/resources/monitoring/methods/slowest` methods throwing exceptions: `curl [THIN_WAR]/resources/monitoring/methods/exceptional` methods throwing exceptions, sorted by exception amount: `curl [THIN_WAR]/resources/monitoring/methods/unstable` See you at [Java EE Performance, Monitoring and Troubleshooting](http://workshops.adam-bien.com/performance.htm) and/or [Java EE Microservices](http://workshops.adam-bien.com/microservices.htm) workshops
