Hi

I am not sure about the Read Cache & Buffer headers but for defunc process you can use

ps -ef |grep -i defun

You can use kmtune(1m) (kctune(1m) on 11.23) to find buffer cache parms:
kmtune | fgrep dbc
dbc_max_pct 3 - 3
dbc_min_pct 3 - 3

You can find read cache hit rate in glance in the global disk report

You can see the size of buffer cache in the memory report

Measureware will also collect this data

extract -xp -gG -f /tmp/global.txt

This will extract the global metrics and buffer cache hit rate and buffer cache size are there.

Re: Read Cache, Buffer headers and defunct processes

Hello All,

Thanks for your reply.

I have the output for the commands,

root@####:(root)> kmtune | fgrep dbc
dbc_max_pct 15
dbc_min_pct 5
root@####:(root)>

root@####:(root)> extract -xp -gG -f /tmp/global.txt
Writing GLOBAL data to file /tmp/global.txt
Writing GLOBAL data to file /tmp/global.txt
root@####:(root)>

How can I read that file?

My requirement is, I have to monitor the usage by OVO and need commands to find the usage. Appreciate your help in this.
