Number of I/O’s for Batch Jobs / Processor Time per I/O for Batch Jobs
Number of I/O’s for Batch Jobs
This graph gives statistics about the I/O characteristics of an average batch job. The I/O sections show both
asynchronous I/O and synchronous I/O. An increase in the number of batch synchronous I/O over a time period
can indicate that:
• More batch work is being done.
• Work management settings of the partition are changed.
• An application has been changed.
Processor Time per I/O for Batch Jobs
This graph shows the average processor seconds per I/O for the batch jobs. An increase in batch job
processor utilization can result when jobs use more and more processor over time.
