Identifier:db2.tbsp_avg_io_time
Database Object Monitored:Table Space
Category:Buffer Pool and I/O
Description:Average time for a single I/O during the previous interval.
Equation:DELTA(db2. tbsp_total_pool_io_time) / DELTA(db2. tbsp_total_pool_reads + db2. tbsp_total_pool_writes)
Usage Notes:This value indicates how much time (measured in milliseconds) on average is spent to complete a single I/O. Look for significant increases in this value. They may indicate that the DASD associated with this pool needs to be reorganized.
| Note: | For multiple buffer pools, the data is combined and only the aggregate number is returned. |
