Re: turning up logging using the web UI, can't get more than INFO
: We have a pretty standard out-of-the-box solr/jetty setup. Using the web : UI at /solr/admin/logging, for WARNING or SEVERE we get less logging, but : none of CONFIG, FINE or FINEST result in any *more* logging than just at : INFO. The UI (and the underlying Solr API) lets you change the log levels used to filter what messages are *produced* by the loggers - but there is a seperate setting that controls which messages are *accepted* by each log handler (ie: you might have multiple log handlers: one writing errors to console, one writting errors and warnings to a problems.txt file, and one writing all log messages to a full_log.txt file) There is no Solr API/UI for changing the levels on the handlers, it can only be done via the underlying log framework configuration. My understanding is that folks who like using the run time UI for toggling the log levels in Solr typically setup their underlying framework config so that at least one handler is configured to recieve accept at the FINEST level, but the root loger is configured to only produce at the INFO (or WARNING) level. Then, when the situation arrises, using the UI to temporarily switch a logger to the FINE or FINEST levels will be written out by that handler. : Is there another place to look for something that might be controlling : that? Maybe a threshold=INFO somewhere? We've been unable to find : anything. FYI: there is a threshold param on the /admin/logging handler in 4.0, but (AFAIK) it controls the threshhold of messages recorded by Solr's internal Log Watcher for display in the UI screens (not on the console or in log files) : We're trying to turn up logging because our solr indexing server is hanging : at least once a day and we're trying to find out why.

Re: turning up logging using the web UI, can't get more than INFO
It is possible. Also, those settings are not saved across restarts. You really should use a logging properties file. Other ways to check on freezes: 1) run garbage collection logging or monitoring. 2) poll the statistics requesthandler and log. 3) poll the thread list and log.

To enable logging, you can just pass a system property to Jetty on startup: java -Djava.util.logging.config.file=etc/logging.properties -jar start.jar This will use Java Util Logging to log to a file based on the config in etc/logging.properties. Logs will be written in the logs directory. It is also possible to setup log4j or other popular logging frameworks.
