Workload snapshots

A workload snapshot is a set of job submission and completion records that are imported from the LSF cluster event file (lsb.events). Use the Workload Snapshots tab in the LSF Simulator web console to manage the workload snapshot functions.

About this task

The Workload Snapshots tab in the LSF Simulator web console displays an overview of all LSF workload snapshots that you imported or created for the LSF Simulator and allows you to perform additional actions on these workload snapshots.

Procedure

  • Click Import to import a new LSF workload snapshot.

    Import the LSF workload snapshot from your production cluster by specifying the events log directory, which must contain the lsb.acct and lsb.event files, and by specifying the time range of job submission events that you want to include.

    Note: The LSF Simulator host must be a server or client in the LSF cluster. In addition, the LSF directory that you specify must be mapped into the container when you started the LSF Simulator service with the bcogn start -v command.
    For example, if you started the LSF Simulator service with the following command:
    ./bcogn start -v "/production_cluster_sharedir/lsf:/production_cluster_sharedir/lsf"
    Specify the following LSF directory for the cluster1 cluster:
    /production_cluster_sharedir/lsf/work/cluster1/logdir

    The workload snapshot import process might take several minutes, depending on the number of job records to import. During this time, the workload snapshot appears in the Workload Snapshots tab with (importing) beside its name.

  • Click the name of an existing workload snapshot to view details on that workload snapshot.
  • Click the Clone action item to copy and modify an existing workload snapshot.

    Use the Workload Selection For Modification filters and the Modify Options checkboxes to modify an existing workload snapshot to create a new workload snapshot.

    For more details on modifying the workloads with the wconvert script, refer to Using modification scripts.
