Spectrum LSF : accounting Logs for resource usage statistics





 The bacct command uses the current lsb.acct file for its output. Displays a summary of accounting statistics for all finished jobs (with a DONE or EXIT status) submitted by the user who invoked the command, on all hosts, projects, and queues in the LSF system. bacct displays statistics for all jobs logged in the current Platform LSF accounting log file: LSB_SHAREDIR/cluster_name/logdir/lsb.acct.

The lsb.acct file is the batch job log file of LSF. The master batch daemon
mbatchd generates a record for each job completion or failure. The record is
appended to the job log file lsb.acct

The file is located at  LSB_HOMESHAREDIR/cluster_name/logdir

[root@c61f4s20 conf]# bacct
/lsf_home/work/CI_cluster1/logdir/lsb.acct: No such file or directory
[root@c61f4s20 conf]#

NOTE: Create a file "lsb.acct"  at LSB_HOMESHAREDIR/cluster_name/logdir
and restart LSF daemons to take your modifications.

-------------------------------
1) Submit a  job:

[lsfadmin@localhost ~]$ bsub
bsub> sleep 400
bsub> Job <232> is submitted to default queue <normal>.

2) Check status

[lsfadmin@localhost ~]$ bjobs
JOBID   USER    STAT  QUEUE      FROM_HOST   EXEC_HOST   JOB_NAME   SUBMIT_TIME
232     lsfadmi RUN   normal     localhost   c712f6n07   sleep 400  Jan 25 01:25

3) Verify the statistics  on jobs submitted by the USER  called lsfadmin  by using  bacct command
[lsfadmin@localhost ~]$ bacct

Accounting information about jobs that are:
  - submitted by users lsfadmin,
  - accounted on all projects.
  - completed normally or exited
  - executed on all hosts.
  - submitted to all queues.
  - accounted on all service classes.
