Re: Better pagecache statistics ?

Hi,

- How much is just file system cache (regular file data) ?

This is just a thought of mine:
/proc/slabinfo?

- How much is shared memory pages ?
- How much is mmaped() stuff ?

cat /proc/vmstat | grep nr_mapped
nr_mapped 77105

But yes, this doesn't give you a detailed account.

- How much is for text, data, bss, heap, malloc ?

Again, this is just a thought of mine: Couldn't you get this information from /proc/<pid>/maps or from the nicer and easier to parse procps application: pmap <pid>?

Thanks,

Hareesh
