> A couple suggestions to improve the readability of the debug logs.
> # Can the transaction ID be put on every debug log entry, similar to how the
> thread ID is on every debug log entry? Then you could grep for a particular
> transaction ID and only see those messages.
> # Can we get a squid.log field for transaction ID? Then you can go looking
> for it in debug log.
> # Some messages currently have transaction ID inside of square braces, but
> square braces are used elsewhere. For example:
> \\
> {noformat}[Oct 19 15:56:16.140] Server {0x2b3dbf130700} DEBUG: (http)
> [147596] State Transition: SM_ACTION_ORIGIN_SERVER_OPEN ->
> SM_ACTION_SERVER_READ{noformat}
> In the above example 147596 is transaction ID. But look at this:
> \\
> {noformat}[Oct 19 10:29:10.273] Server {0x7ff0c9de08c0} DEBUG:
> <HttpClientSession.cc:498 (release)> (http_cs) [2] session released by sm
> [1]{noformat}
> Square braces notation also used for HTTP2 client session and state machine.
> So please pick something unique for transaction ID.
> # Is it necessary for http header debug messages to be split across so many
> lines? At a minimum can the header name and header value be on the same
> line? Its hard to read debug log output when there are many clients making
> requests at same time as the messages are not grouped together/written
> sequentially.
