topas look at the right hand side corner
I want to know that how can I calculate the computational memory instead of using topas so that values can be used in scripts to generate events.

1. Memory pages (A)
2. Free pages (B)
3. numperm percentage (C)
Then you can calculate % computational memory using the below formula:
((A  B)  ((C * A)/100))/ A )
Basically you are calculating number of memory pages used and subtracting the noncomputational pages.

From "vmstat v' output note down the following values:
1. Memory pages (A)
2. Free pages (B)
3. numperm percentage (C)
Then you can calculate % computational memory using the below formula:
((A  B)  ((C * A)/100))/ A )
Basically you are calculating number of memory pages used and subtracting the noncomputational pages.

Does this differentiate between application and kernel?
