File table overflow

Hi all,

How I can monitor the file table in HP-UX 11.11?
Is there any options in SAM/Glance to inform the user when the value of nfile exceeds.

Hi:

You can use 'sar -v' or glance. With 'glance', toggle the 't'able view.

Regards!

Thank you James. But using this I will get only the realtime output only .Right? But I need the output only when the nfile value exceeds the limit.

Hi (again):

The 'file-ov' column of 'sar's output tells you the number of times the system file table overflowed during the sample interval.

All this aside, you would be far better to tune up your 'nfile' kernel parameter. It uses tiny amounts of memory for large values. When you get to 11.31, the parameter is obsolete too.

You can also use kcusage(1m) to get the value of nfile on 11.23:
$ /usr/sbin/kcusage nfile
Tunable Usage / Setting
nfile 773 / 65536
