How do I reduce the log level of Candlepin?

We get gigas of log entries to /var/log/candlepin/candlepin.log, mostly just stuff like:

2017-04-03 10:05:22,332 [thread=http-bio-8443-exec-4] [req=243254b6-9d7e-487b-a51e-34253384fe86, org=] INFO  org.candlepin.common.filter.LoggingFilter - Request: verb=GET, uri=/candlepin/consumers/e4cd05e3-39ae-4ea1-a2e8-4f29604a07f2/compliance
2017-04-03 10:05:22,379 [thread=http-bio-8443-exec-7] [req=f0bd5fca-f22d-468b-9ba3-712461d2fd22, org=] INFO  org.candlepin.common.filter.LoggingFilter - Request: verb=GET, uri=/candlepin/consumers/2b316c03-6733-4527-acfe-f13c48507bcc/guests

...etc...etc...

The info at Red Hat Satellite 6: key log files and how to enable debug logging (Foreman, Katello, Puppet, Pulp, Candlepin, Hammer, etc.) tells us we can change to log4j.logger.org.candlepin=DEBUG to get more logging, and also says we can add this if the logging is excessive:

log4j.logger.org.candlepin.resource.ConsumerResource=WARN
log4j.logger.org.candlepin.resource.HypervisorResource=WARN

I have done so and restarted Tomcat (actually restarted all using katello-service), but still get the INFO lines like above.

I assume we can change to log4j.logger.org.candlepin=WARN to reduce the log size. However, if I only want to get rid of the INFO messages above and keep other INFO messages. What do I do? I thought the... ConsumerResource=WARN above should do the trick, but I don't understand the common logging filter thing.
