You must submit the commands from the host on which the daemon is running (only applicable to the bld).
You can temporarily change the class or message log level for the bld and blcollect daemons without changing lsf.licensescheduler.
The message log level you set is in effect from the time you set it until you turn it off or the daemon stops running, whichever is sooner. If the daemon is restarted, its message log level is reset back to the value of LS_LOG_MASK and the log file is stored in the directory specified by LSF_LOGDIR.
