AIX

Hi,

I have written an application which reports the CPU information like user cpu%, sys cpu%, idle cpu% and wait cpu%. The application is built on an AIX 5.1 machine. The appliaction runs fine on AIX 5.1 and 5.2 and their results match with that of the topas command. But when I run the application on AIX 5.3 for some reason the values are not matching with that of the topas command (eg: usr and sys cpu% are always 0 while topas shows values for these fields)

I am using the knlist API to get the address of the kernel symbol "cpuinfo". Then using the address as offset I am reading the cpu values from the kernel file "/dev/kmem". I am using the structure "struct cpuinfo" for storing the values retrieved.

I made a walk thru into the code and found that the knlist API has successfully returned the offset. I am going mad on what could be wrong.

Could anyone please let me know on what could be wrong....Is there any fixpack that need to be applied for AIX 5.3.....????

I found that the knlist API is returning proper offset into the /dev/kmem file but the problem occurs when the dual core capability of the cpu is turned on the value is not getting properly updated in the /dev/kmem file. But the valu in /dev/kmem is updated properly if the dual core capability is turned -off.

Could anyone please let me know if it is a problem with the AIX 5.3??


Thanks.
