OEM Chart Shows Bad IO Response Time Not Corroborated by Operating System Statistics (Doc ID 2215352.1)

Last updated on AUGUST 25, 2017

Applies to:

Oracle Database - Enterprise Edition - Version 11.2.0.3 and later
Information in this document applies to any platform.

Symptoms

Upon review of OEM Charts for bad IO response time as well as underlying views:  GV$ASM_DISKGROUP_STAT / GV$ASM_DISK_STAT, it is clear that those values do not correlate to the same data as reported by AIX Unix IO data such as iostat, sar etc.  In short, reported OEM statistics are not corroborated at DB and/or OS level.
