# Timer Interceptor

DEPRECATED

This interceptor logs the amount of time in milliseconds. In order for this interceptor to work properly, the logging framework must be set to at least the `INFO` level. This interceptor relies on the Commons Logging API to report its execution-time value.

## Parameters

- `logLevel` (optional) - what log level should we use (`trace, debug, info, warn, error, fatal`)? - default is `info`
- `logCategory` (optional) - If provided we would use this category (eg. `com.mycompany.app`). Default is to use `com.opensymphony.xwork2.interceptor.TimerInterceptor`.

The parameters above enables us to log all action execution times in our own logfile.

## Extending the Interceptor

This interceptor can be extended to provide custom message format. Users should override the `invokeUnderTiming` method.

## Examples

     <!-- records only the action's execution time -->
     <action name="someAction" class="com.examples.SomeAction">
         <interceptor-ref name="completeStack"/>
         <interceptor-ref name="timer"/>
         <result name="success">good_result.ftl</result>
     </action>

     <!-- records action's execution time as well as other interceptors-->
     <action name="someAction" class="com.examples.SomeAction">
         <interceptor-ref name="timer"/>
         <interceptor-ref name="completeStack"/>
         <result name="success">good_result.ftl</result>
     </action>
