Set daemon timing levels

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.

LSF_TIME_RES is not supported on Windows.

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 off the timing log level 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.


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 that are 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]
