You can try use switchMediator with something like that below. But be aware and dont try to use <log level =" full "> on HTML, unless you have proper messageBuilder and messageFormater for that content type. In default WSO2 ESB tryes to convert using xml builder, and it will ended with error. I tried this on wso2ei 6.5.0 but i believe it should work on esb 5.0.0.

<switch source="$trp:Content-Type">
     <case regex="^(application\/(json|x-javascript))(;.*)?$">
        <log>
           <property name="Looks like Json format" expression="$trp:Content-type"/>
        </log>
     </case>
     <case regex="^(text\/html)(;.*)?$">
        <!--Don't log full, unless you have proper axis2.xml configuration for that contentType-->
        <log level="custom">
           <property name="Looks like HTML format" expression="$trp:Content-type"/>
        </log>
     </case>
     <default>
        <log level="custom">
           <property name="Unknown format" expression="$trp:Content-type"/>
        </log>
     </default>
 </switch>
