> Once I finally got log4j logging working, I was slightly surprised by the message related to SOLR-3426. I did not really consider that to be a big deal, because if I want to look at my log, I'll be on the commandline anyway.
> I was even more surprised to find that I cannot change any of the log levels from the admin gui. My default log level is WARN for performance reasons, but every once in a while I like to bump the log level to INFO to troubleshoot a specific problem, then turn it back down. This is very easy with jdk logging in either 3.x or 4.0. I changed to log4j because it easily allows me to put the date of a log message on the same line as the first line of the actual log message, so when I grep for things, I have the timestamp in the grep output.
> Currently the only way for me to change my log level is by updating log4j.properties and restarting Solr. If the capability to figure this out on a class-by-class basis isn't there with log4j, I would at least like to be able to set the root logging level. Is that possible?
