Logging Requests and Responses for specific 400 Errors
Hi,
We're trying to debug an intermittent 400 error our client see. Is it
possible to configure ATS to log the full request and response for
ERR_UNKNOWN/400 errors?

Hey Scott,
If it lets you see the full request that would be awesome to have
available. Given my lack of history writing ATS plugins, I'm afraid I'd
cause more problems than I'm trying to debug.

I'm not aware of a way to do this with opensource ATS either. Yahoo has an internal plugin which forks the request and publishes into an external redis-based datastore. You might try doing something similar. I'll pressure internal folks to opensource our plugin if there is interest.

Combing through those docs again I don't think ATS can log full requests
and responses. The closest logging parameter that seems to be offered is
"cqtx" which logs the full request sans headers (which we need to
see...Squid has log_mime_hdrs that does this but I don't see an equivalent
in ATS), and I don't see any field that logs the full response.
If anybody knows differently, I'd love to be wrong. Thanks again.

Oh awesome. Thank you Miles. I was having trouble piecing it together from
the docs.

I think you can do this in the logs_xml.config with LogFilterslogs_xml.config — Apache Traffic Server 6.2.0 documentation
You first describe the log you want (https://docs.trafficserver.apache.org/en/latest/admin-guide/monitoring/logging/log-formats.en.html#custom-logging-fields or the log builder http://trafficserver.apache.org/logbuilder/
<LogFormat> <Name = "log_errors"/> <Format = "%<cqtq> more stuff here..."/></LogFormat>
then the filter<LogFilter>
<Name = "log_errors"/>
<Condition = "pssc CONTAIN 403"/>
<Action = "ACCEPT"/>
</LogFilter>

Have you enabled debug logs in ATS config?
