WSO2 ESB How to see the outsequence log - wso2

Question

I have wrote a proxy in WSO2 ESB. using the log files or the Monitor functionality I can see the logs for all the message mediation in the inSequence sequence mediator, but I can't find the logs for the outSequence. My Proxy example is:
<proxy name="FlightStatusService"
transports="https http"
startOnLoad="true"
trace="enable">
<description/>
<target>
<inSequence>
<property name="FORCE_SC_ACCEPTED" value="true" scope="axis2"/>
<property name="OUT_ONLY" value="true"/>
<property name="TIME_1"
expression="get-property('SYSTEM_TIME')"
scope="default"
type="LONG"/>
<property xmlns:air="http://airline.services.esb.wso2.packt.com"
name="airlineInTransport"
expression="fn:concat('Airline Company - ', //air:updateStatus/air:airline)"
scope="transport"/>
<property name="airlineInDefault"
expression="get-property('transport','airlineInTransport')"
scope="default"/>
<switch xmlns:air="http://airline.services.esb.wso2.packt.com"
source="//air:updateStatus/air:airline">
<case regex="EK">
<event topic="flightStatus/emirates"/>
</case>
<case regex="AA">
<event topic="flightStatus/aa"/>
</case>
<case regex="DL">
<event topic="flightStatus/delta"/>
</case>
<default>
<log level="custom">
<property name="noAirline" value="There is no Airline with these letters"/>
</log>
</default>
</switch>
</inSequence>
<outSequence>
<property name="TIME_2"
expression="get-property('SYSTEM_TIME')"
scope="default"
type="LONG"/>
<script language="js">var time1 = mc.getProperty("TIME_1");
var time2 = mc.getProperty("TIME_2");
var timeTaken = time2 - time1;
print("-------------- " + timeTaken + " ms -----------------");
mc.setProperty("RESPONSE_TIME", timeTaken);</script>
<log level="full" category="DEBUG">
<property name="airlineInTransport"
expression="get-property('default', 'airlineInDefault')"/>
<property name="Time Duration in ms: " expression="get-property('RESPONSE_TIME')"/>
</log>
<send/>
</outSequence>
</proxy>

Answer 1

Since your proxy is support for OUT_ONLY Activity, outSequence will not get hit.
