> For 11.0.0 I'd like to cut ATS down to two log files by default: error.log

> The proposal:

> 1. Everything that goes to diags.log and traffic.out today goes to error.log
> instead, in one line format with a level and tag on every line (#14010 does
> the format part).
> 2. squid.log is renamed access.log.
> 3. If someone wants a different split, such as some kinds of messages in
> their own file, or sent to syslog or a pipe, that's a configuration option.
> error.log and access.log stay the default.

> This is the same split httpd and nginx use, and it's what most operators

> need an upgrading note for anyone whose log shipping, alerts or scripts read
> them.
