             Summary: logstats: add ability to report stats per user instead of host
                 Key: TS-5069
                 URL: https://issues.apache.org/jira/browse/TS-5069
             Project: Traffic Server
          Issue Type: Bug
          Components: Logging, Tools
            Reporter: Gancho Tenev


We would like to enhance {{traffic_logstats}} with the ability to report stats per user instead of host (from the URI).

Currently the {{traffic_logstats}} expects a binary squid log format defined in the following ATS log config and aggregates and reports stats per the authority part of the URI ({{host:port}} in an usual use-case)

{code}
<Format = "%<cqtq> %<ttms> %<chi> %<crc>/%<pssc> %<psql> %<cqhm> %<cquc> %<caun> %<phr>/%<pqsn> %<psct>"/>
{code}

It would be useful for our use-case to be able aggregate and report stats based on the 8th squid log field which is an username of the authenticated client {{%<caun>}}).

In our use-case we need to aggregate and report stats per CDN-customer-specific-tag. 

For example the new functionality would allow us to replace {{%caun}} with a random header content {{%<\{@CustomerTagHeader\}cqh>}} and report stats per CDN customer by using a new command line parameter {{--report_per_user}} w/o adding extra fields to the binary squid format log expected by {{traffic_logstats}} and keep it backward compatible with the previous version.
