Shawn Heisey created SOLR-3979:
----------------------------------
Summary: slf4j bindings other than jdk -- cannot change log levels
Key: SOLR-3979
URL: https://issues.apache.org/jira/browse/SOLR-3979
Project: Solr
Issue Type: Bug
Affects Versions: 4.0
Reporter: Shawn Heisey
Fix For: 4.1
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?
