spymemcached - is it possible to disable the logging system?

we are using the spymemcached memcached client but we didn't discove开发者_开发技巧red how we could disable the logging system.

How could we at runtime change the current logging system to something like log4j or sl4j?

Notice: We could pass some VM arguments, but the problem is: we can't change our server configuration. Is it possible to pass these VM arguments at runtime? If possible, how could we do that?

I stopped excessive Tomcat logging to catalina.out by doing this before creating the MemcachedClient object:

System.setProperty("net.spy.log.LoggerImpl",
  "net.spy.memcached.compat.log.SunLogger");
Logger.getLogger("net.spy.memcached").setLevel(Level.WARNING);

I know it's an old question and this solution will not work at runtime, but I had a similar problem and only found this question. You can find a way to set spymemcached logging level via tomcat config files here.

Important part:

A short summary how you can make spymemcached more silent:

Add the following to $CATALINA_HOME/bin/catalina.sh:

CATALINA_OPTS="-Dnet.spy.log.LoggerImpl=net.spy.memcached.compat.log.SunLogger"

Add this to $CATALINA_HOME/conf/logging.properties:

(A handler's log level threshold can be set using SEVERE, WARNING, INFO, CONFIG, FINE, FINER, FINEST or ALL)

net.spy.memcached.level = WARNING

To make only the MemcachedConnection less verbose:

net.spy.memcached.MemcachedConnection.level = WARNING
