[jetty-users] Help understanding log messages

[John English]

I'm a bit puzzled by some messages I see in my jetty.log files (Jetty
9.4.6) which look like this:

2018-04-17 18:42:30.803:INFO:oejshC.ROOT:qtp30728890-4405: Login:
node01ouqe3mcfxfm61cjjsyrcdn6gw468

I see these at irregular intervals at all times of day, including in the
wee small hours when there are no requests in the request log for an
hour or two either side.

Since the server isn't started by root, and uses a custom login method,
why does it all mean? I presume qtpXXXis a thread ID, but what does ROOT
refer to in this context, which class is oejshC that is emitting this,
and what does nodeXXX refer to?

I used Jetty 8 until fairly recently and don't recall seeing anything
like this then...

Thanks to anyone who can explain this for me!

Hi,

I'm a bit puzzled by some messages I see in my jetty.log files (Jetty 9.4.6)

Latest Jetty 9.4.x code does not have any log statement that starts
with "Login:".
It must some something else deployed to or configured in Jetty, or
perhaps some older Jetty version that had that logging.

I see these at irregular intervals at all times of day, including in the wee
small hours when there are no requests in the request log for an hour or two
either side.
Since the server isn't started by root, and uses a custom login method, why
does it all mean? I presume qtpXXXis a thread ID,

The thread is is 4405, qtpXXX is the Jetty thread pool, so this is a
Jetty pooled thread (normal situation).

but what does ROOT refer to in this context

To a web application deployed to the root context, or "/".
Do you have a ROOT directory in your $JETTY_BASE/webapps ?

, which class is oejshC that is emitting this, and what
does nodeXXX refer to?

If you grep the text and binary files in your $JETTY_BASE looking for
"Login:" what do you find ?

Ah, OK, many thanks. It is indeed a rogue log message for debugging
purposes that has accidentally been left enabled in the live system. The
"nodeXXX" is the session ID.

Is "oejshC" an abbreviation for
org.eclipse.jetty.server.handler.ContextHandler, perhaps?

Likely, yes.
