monitor open files in the system

[eran maor]

Hi

i had a problem in hp-ux 11.00 with 4 g.b memory.
got file : table is full .
i increase the size of the nfile and ninode .

i m looking for a way to monitor the open files in my system .

I'm not 100% sure if you want an automated process for looking at the files & raising a warning if appropriate or just montioring an open file. The latter I can help with
find the process id (pid) attached to the file i.e
# fuser /.../file
then use glance (which I hope you have!)
when in glance type F (shift+f) then enter the pid

Good luck

hi,
if you just want to monitor the amount of open files, then use:
sar -v 1 1
this will show ninode, nfiles and nproc usage.

if you really want to view which files are in use then go for "lsof".

regards,
Thierry.

Hi,

add your crontab file with a raw like this :
0 * * * * /usr/lbin/sa/sa1 1200 3.
Then you are able to monitor also the history of nfile and his max value with sar -v.
Create dir /var/adm/sa, the output dir of sa1.

lsof is superb for listing open files (and its free). To list open files in a specific directory use:

$LSOF_HOME/lsof +D {FULLPATH_DIRECTORY_NAME}
