25 Nov/13 - Trick: Introduce Activity by I/O HBA In OEDB ProgreSQL Type
In this small document we describe the results of the different tests in order to come up with aggregated load parameters by I/O channel (HBA). The idea is to process the I/O parameters by LUN and calculate one value for that interval for the HBA/channel and this via a PGSQL script that extracts/process data and writes the results directly into the ProgreSQL TeamQuest EDB.
Our goal is to decrease the need for large data processing in ITSAR in order to come up with similar values. It will increase your performance in these specific HBA related reports.
