How can we find out the kernel memory in RHEL as 4

[Ivan Ferreira]

I don't understand very well your question but all memory related information can be obtained in /proc/meminfo:

cat /proc/meminfo

[AnthonySN]

one more question,
can u shed some light on massif plugins to valgrind in RHEL 4

as per red hat site

"the memprof memory profiling and leak detection tool is no longer included in Red Hat Enterprise Linux 4. The memcheck and massif plugins to valgrind (which is newly included in Red Hat Enterprise Linux 4) provide similar functionality to memprof."

[Vamsidin]

NO other info is required.....


Kernal Internal Mem usage is obtained byh

vmstat -m

and in perticular to view slab usage

slabtop [- d sec] [-s sort] [-o]

d-- number of seconds
s-- sort order
o-- display slabtop

eg:

sort -k6,6 -n < /proc/slabinfo | cut -f 1 -d:
