Why cisco:wsa:w3c src field is not extracted ?

[sbnainfosec]

I am facing a challenging issue with the CISCO WSA Add-on version 3.3.0, what happens is that I can not use/rename/EXTRACT/FIELDALIAS/COALESCE to get src_ip field into src from one location. As a reference, I am receiving wsa logs from two different sources/location, and both have the same configuration/OS version, however, if the wsa data comes from location A, the src field works fine with a FIELDALIAS, but if the wsa data comes from location B, the src field never appears, even if I apply a FIELDALIAS or any other action. Same Add-on applies for both locations.

Any idea will be highly appreciate it.

Current Splunk version: 7.3.4

Are you using host in the stanza in props for extraction the field. if yes then make sure this is not having high precedence in any other App with this stanza.
eg:
host = abc.com.us
[host::com]

host=a.com.us
[host=a.com*]

Hopefully this solves your problem.
