Per Splunk's default field extractions:
[access-extractions]
# matches access-common or access-combined apache logging formats
# Extracts: clientip, clientport, ident, user, req_time, method, uri, root, file, uri_domain, uri_query, version, status, bytes, referer_url, referer_domain, referer_proto, useragent, cookie, other (remaining chars)
Your logs seem formatted correctly, but perhaps you have not assigned them the sourcetype of "access_combined". What sourcetype do your Apache logs currently show?
