Setting Daemon Message Log to Debug Level
The message log level for LSF daemons is set in lsf.conf with the parameter
LSF_LOG_MASK. To include debugging messages, set LSF_LOG_MASK to one of:
◆ LOG_DEBUG
◆ LOG_DEBUG1
◆ LOG_DEBUG2
◆ LOG_DEBUG3
By default, LSF_LOG_MASK=LOG_WARNING and these debugging messages are
not displayed.
The debugging log classes for LSF daemons is set in
lsf.conf with the parameters
LSB_DEBUG_CMD, LSB_DEBUG_MBD, LSB_DEBUG_SBD,
LSB_DEBUG_SCH, LSF_DEBUG_LIM, LSF_DEBUG_RES.
The location of log files is specified with the parameter LSF_LOGDIR in
lsf.conf.
You can use the
lsadmin and badmin commands to temporarily change the class, log
file, or message log level for specific daemons such as LIM, RES,
mbatchd, sbatchd,
and
mbschd without changing lsf.conf.
How the message
log level takes
effect
The message log level you set will only be 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 LSF_LOG_MASK and the
log file is stored in the directory specified by LSF_LOGDIR.
Limitations
When debug or timing level is set for RES with lsadmin resdebug, or lsadmin
restime
, the debug level only affects root RES. The root RES is the RES that runs
under the root user ID.
Application RESs always use
lsf.conf to set the debug environment. Application
RESs are the RESs that have been created by
sbatchd to service jobs and run under
the ID of the user who submitted the job.
This means that any RES that has been launched automatically by the LSF system will
not be affected by temporary debug or timing settings. The application RES will retain
settings specified in
lsf.conf.
Debug commands for daemons
The following commands set temporary message log level options for LIM, RES,
mbatchd, sbatchd, and mbschd.
lsadmin limdebug [ -c class_name] [ -l debug_level ] [ -f logfile_name ] [ -o ]
[
host_name ]
lsadmin resdebug [ -c class_name] [ -l debug_level ] [ -f logfile_name ] [ -o ]
[
host_name ]
badmin mbddebug [ -c class_name] [ -l debug_level ] [ -f logfile_name ] [ -o ]
badmin sbddebug [ -c class_name] [ -l debug_level ] [ -f logfile_name ] [ -o ]
[
host_name ]
badmin schddebug [ -c class_name] [ -l debug_level ] [ -f logfile_name ] [ -o ]
