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.
