solr UI logging when using logback?
i have logging working for the most part with logback 1.0.13 and slf4j
1.7.5 under solr 4.3.0 (or previously under solr 4.2.1)
with two exceptions, i'm very happy with the setup as i can get all the
jetty request logs, and various solr service events logged out with
rotation, etc
BUT i havent figured out what i need to do to get the logging events to
display in the SOLR admin ui
e.g. at http://solr-hostname:8983/solr/#/~logging
AND
i'm wondering if its possible to get the jetty start log managed under
logback
anybody have any pointers on these topics?

the configuration details of my setup are summarized in the rpm building
process here

Ah I vaguely remember seeing that when we first used logback (on 4.0), as
Shawn says I think its the problem that as logback is starting up, where can
it log before it has configured its logging (catch-22), answer it has to log
to its own internal format.
If memory serves we just disabled that logging, but I don't recall the exact
syntax, I don't have access to my work setup now, but will try and check
tomorrow.
We don't use the request log, so that is one difference.

That's really interesting. This appears to be the initialization of
logback itself, not jetty. If nobody steps up who's familiar with
slf4j/logback with jetty, you might need to use a mailing list for one
of those projects.
Thanks,

thanks for the pointer on the missing logwatcher for logback...i'll take a
look at that.
on the jetty logging side of things i get nearly all the jetty logging but
the initial startup logs which seem to happen prior to the other logging
jars getting loaded. perhaps i need to add a few more statements to my
logback.xml config, but it seems to be getting its naming
YYYY_MM_DD-HHmmssSSS.start.log and pattern from somewhere outside logback.
in the YYYY_MM_DD-HHmmssSSS.start.log i get messages like this
cat 2013_05_15-141100827.start.log
Establishing start.log on Wed May 15 14:11:12 PDT 2013

The logging page in the UI is populated by log watcher classes specific
to the logging implementation. Prior to 4.3, the only watcher available
in released Solr versions was the one for java.util.logging. The log4j
watcher was incorporated in the 4.3.0 release. I have been using log4j
since 4.1-SNAPSHOT, but I don't yet have any 4.3 servers in production,
so I can't get logs in my UI.
To get log events in the UI with logback, you would need to implement a
watcher specifically for logback. I don't think this is a high priority
item for the project at the moment, but patches are welcome.

On my setup using the jetty included with Solr and the slf4j/log4j jars
in lib/ext, all jetty log entries are logged to the same file as my Solr
logs, according to my log4j.properties file.
If you have any logging config for jetty itself, then that will be used.
The easiest way to proceed is to simply comment or remove that logging
config. That will cause jetty to find slf4j in the classpath and use
it, which you have already configured to use logback. The example jetty
config does not have any logging configured.
Thanks,
Shawn
