Figure: Jobs Table

The Jobs Table will show a view of all jobs currently doing I/O or Metadata operations. Information from the SMW is integrated with jobstat metrics. The jobstat metrics are flagged to highlight jobs of interest.
  • Avg. I/O Size - Average I/O Size is calculated by View for ClusterStor as the total number of bytes read and written since the given job's inception, divided by the total number of read and write requests since the job’s inception.
  • Metadata Ops - Metadata Ops is calculated by View for ClusterStor as the sum of all the metadata operations since the given job’s inception, from each MDT.

For complete details about the Jobs Table columns, see Jobs Table.

Information in the Jobs Table can be re-sorted by clicking on a column header.

Search for Jobs

If the job ID or apid was running outside the window of time displayed in the Jobs Table, select the Filter icon on the content pane banner to open the Filter Jobs window.

Specify an apid and a time range, and then select Submit.

Optionally, select Set custom time range and select an ending date/time. Do not specify a start time. This will result in a search of the entire database.
