Can you monitor actual 'size in use' for various kernel parameters ?

Simon R Wootton — Tue, 22 Jul 2008 09:47:44 GMT

I'm concerned that some of my kernel parameters are getting close to the limit.

Is there an easy way to monitor 'actual' usage for these chaps instead of just seeing the settings in SAM ?

All help appreciated & rewarded !!

If you have Glance, the "System Tables Report" will show you real time values.

Simon,

If you are on 11iv2 or 11iv3 then take a look at kcusage(1m)

e.g. show usage of nproc kernel parm for last month:

kcusage -m nproc

For 11iv1, I think you'll only be able to look at data from sar -v (and only hsitorical data if you have configured accounting)

Hi Simon,

What about looking at kcusage - I think this should give you what you want.

sysdef might also be worth looking at. I don't have a HP-UX system at the moment so I can't check the output.

Hope this helps,
Paul

sysdef, you can use every OS

but kctune usage is limited in 11iv2 and 11iv3

Set the alarm with kcalarm.
If necessary edit the dictionary file - /etc/opt/resmon/dictionary/kcmond_01.dict

And after that enable monitoring.

Shalom Simon,

The glance system has several useful features.

There is a graphical high water mark for important measures in the kernel and swap.

This lets you see how close you came to running out.

You shouldn't recommend using this "TO BE OBSOLETED" command. Instead use kctune(1m) or kmtune(1m) (11.11).

Hi Simon,
log on as root and use '/usr/sbin/kcweb'.
There is everythink about kernel parameters.
