You can set the GLOG_v environment variable (see 
https://google-glog.googlecode.com/svn/trunk/doc/glog.html#verbose) to the 
desired verbosity level and then restart mesos-slave. If you just want to 
increase the log level without a restart, you can hit the /logging/toggle 
endpoint on the mesos-slave (do curl http://127.0.0.1:5051/help/logging/toggle 
for the online help).
