ASM & Average Disk Response Time
Greetings All, I was hoping that others may have some insight into DB Control and how is reports ASM Disk response times.
First my environment:
Oracle RAC 11g R1 Standard Edition, Patchset 12
Two Node Cluster
Windows x64 2003 R2 DataCenter Edition.
I am leveraging DB Control to monitor the ASM instances along with the db instances. My issue is regarding how db control gathers metrics to report on average response time for the DISKS that make up the Disk Group.
I have two issues:
1.) The overall response time reported in db control for my disk group "DATA" does not jive with the average I calculate based on the numbers being reported by db control. E.g.) I have ten LUNS in my DATA disk group and if I calculate the mean avg response time from each individual disk as reported by db control I don't get the same number being reported by db control. The numbers differ by as much as 20%.
