Monitoring Kernel system tables

[Oliver White]

Can anyone tell me a way to monitor the current usage of kernel tables such as nfile and nflocks WITHOUT using Glance?

The System Tables Report in Glance is extremely useful, and was able to tell us we'd reached our nflocks limit on one of our machines, but management won't spring for the cost of Glance on all our systems just yet.

I'd like just a simple command to tell me how much of these tables is currently in use.

Hi Oliver,

Try this out out if you can't use 'glance'.

# sar -v 10 5

Output like this.

HP-UX beaver B.11.00 A 9000/800 08/09/01

14:59:10 text-sz ov proc-sz ov inod-sz ov file-sz ov
14:59:20 N/A N/A 132/2068 0 1239/2772 0 476/4426 0
14:59:30 N/A N/A 132/2068 0 1195/2772 0 476/4426 0
14:59:40 N/A N/A 132/2068 0 1178/2772 0 476/4426 0
14:59:50 N/A N/A 132/2068 0 1168/2772 0 476/4426 0
15:00:00 N/A N/A 132/2068 0 1161/2772 0 476/4426 0

Unfortunately it does not show 'nflocks'

Hi Oliver,

One last suggestion....
You can actually remove the trial version of glance using 'swremove' and then re-install it to give you another 60 days.... shush! don't tell HP!

hi,
FYI I've heard that you can't reinstall the trial version from the recent application CD's. Never tried it though.

kernel tables can also be monitored with the EMS monitor krmond that comes with the OnlineDiag bundle.

See http://docs.fc.hp.com//hpux/onlinedocs/diag/ems/emd_kern.htm

and

http://docs.fc.hp.com/hpux/pdf/B6191-90024.pdf


The advantage is that tresholds can be defined to notify the user/sysadmin by mail, syslog, textlog, snmp, tcp message etc.
