HTTP EVENT Collector - HttpAppender - how to add hostname

[dsvasani]

Dear All

I am new to Splunk, and we are using log4j2 configuration file with HttpAppender to send logs , but I am not able to add Host name.

This is what I use:

<Http name="Splunk-New" url="http://host:8088/services/collector/raw">
                        <Property name="Authorization" value="Splunk token"></Property>
                        <Property name="Host" value="${hostName}"></Property>
                        <PatternLayout pattern="%-5p %d [%t] [event: %X{correlationId}] %c: %m%n"></PatternLayout>
                </Http>

${hostName} variable used in below line should provide required value for Host. 

<Property name="Host" value="${hostName}"></Property>

Reference from Log4j documentation:
 "The default map is pre-populated with a value for "hostName" that is the current system's host name or IP address"
