# 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`
