Mulesoft:Flow Execution Time

Mulesoft application is based on flows. Every flow has their own execution time. We can calculate this flow execution is couple of ways. But Mulesoft provides one of the easy way to calculate this flow execution time by using interceptor . Timer interceptor (<timer-interceptor/>) is one of the mule interceptor to calculate Mulesoft flow execution time.

Here is flow diagram for timer-interceptor

Here is code for timer-interceptor to implement in your application

<flow name="muleTimerInterceptorFlow">
<http:listener config-ref="HTTP_Listener_Configuration" path="/" doc:name="HTTP"/>               <timer-interceptor/>
     <set-payload doc:name="Set Payload" value="Hello World"/>
<logger message="#[payload]" level="INFO" doc:name="Logger"/>
</flow>
</mule>

 <timer-interceptor/> tag display time in milliseconds.

You can customize flow execution time to replace <timer-interceptor/>  with  <custom-interceptor>.
In this custom interceptor you need to mention your custom interceptor java class.

<custom-interceptor class=”com.vanrish.interceptor.TimerInterceptor” />
