Setting Daemon Timing Levels
Chapter 42
Troubleshooting and Error Messages
The timing log level for LSF daemons is set in lsf.conf with the parameters
LSB_TIME_CMD, LSB_TIME_MBD, LSB_TIME_SBD, LSB_TIME_SCH,
LSF_TIME_LIM, LSF_TIME_RES.
The location of log files is specified with the parameter LSF_LOGDIR in
lsf.conf. Timing is included in the same log files as messages.
To change the timing log level, you need to stop any running daemons, change
lsf.conf, and then restart the daemons.
It is useful to track timing to evaluate the performance of the LSF system. You
can use the lsadmin and badmin commands to temporarily change the timing
log level for specific daemons such as LIM, RES, mbatchd, sbatchd, and
mbschd without changing lsf.conf.
How the timing
log level takes
effect
The timing log level you set will only be in effect from the time you set it until you
turn the timing log level off or the daemon stops running, whichever is sooner. If the
daemon is restarted, its timing log level is reset back to the value of the
corresponding parameter for the daemon (LSB_TIME_MBD, LSB_TIME_SBD,
LSF_TIME_LIM, LSF_TIME_RES). Timing log messages are stored in the same file as
other log messages in the directory specified with the parameter LSF_LOGDIR in
lsf.conf.
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.
An application RES always uses lsf.conf to set the debug environment. An
application RES is the RES that has 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.
Timing level commands for daemons
The total execution time of a function in the LSF system is recorded to evaluate
response time of jobs submitted locally or remotely.
The following commands set temporary timing options for LIM, RES, mbatchd,
sbatchd, and mbschd.
lsadmin limtime [-l timing_level] [-f logfile_name] [-o] [host_name]
lsadmin restime [-l timing_level] [-f logfile_name] [-o] [host_name]
badmin mbdtime [-l timing_level] [-f logfile_name] [-o]
badmin sbdtime [-l timing_level] [-f logfile_name] [-o] [host_name]
badmin schdtime [-l timing_level] [-f logfile_name] [-o]
For debug level examples, see “Setting Daemon Message Log to Debug Level”
on page 540.
