Setting Daemon Message Log to Debug Level ◆ % badmin sbddebug -f hostB/myfolder/myfile hostA Log messages for sbatchd running on hostA, to the directory myfile on the server hostB, with the file name myfile.sbatchd.log.hostA. The debug level is the default value, LOG_DEBUG level in parameter LSF_LOG_MASK. ◆ % badmin schddebug -l 2 Log messages for mbatchd running on the local host and set the log message level to LOG_DEBUG2. This command must be submitted from the host on which mbatchd is running because host_name cannot be specified with schddebug. ◆ % lsadmin resdebug -o hostA Turn off temporary debug settings for RES on hostA and reset them to the daemon starting state. The message log level is reset back to the value of LSF_LOG_MASK and classes are reset to the value of LSF_DEBUG_RES, LSF_DEBUG_LIM, LSB_DEBUG_MBD, LSB_DEBUG_SBD, and LSB_DEBUG_SCH. The log file is reset to the LSF system log file in the directory specified by LSF_LOGDIR in the format daemon_name.log.host_name. For timing level examples, see “Setting Daemon Timing Levels” on page 543. 542 Administering Platform LSF
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. For a detailed description of lsadmin and badmin, see the Platform LSF Reference. Administering Platform LSF 543
