System event log

The LSF daemons keep an event log in the lsb.events file. The mbatchd daemon uses this information to recover from server failures, host reboots, and mbatchd restarts. The lsb.events file is also used by the bhist command to display detailed information about the execution history of batch jobs, and by the badmin command to display the operational history of hosts, queues, and daemons.

By default, mbatchd automatically backs up and rewrites the lsb.events file after every 1000 batch job completions. This value is controlled by the MAX_JOB_NUM parameter in the lsb.params file. The old lsb.events file is moved to lsb.events.1, and each old lsb.events.n file is moved to lsb.events.n+1. LSF never deletes these files. If disk storage is a concern, the LSF administrator should arrange to archive or remove old lsb.events.n files periodically.

CAUTION:

Do not remove or modify the current lsb.events file. Removing or modifying the lsb.events file could cause batch jobs to be lost.
