Useful Commands....

[Scott McDade]

I am new to HPUX 11i and I am doing some porting of a C based application from Win32 to HPUX and I am looking for some commands that help me monitor the applications usage and efficiency. I am looking for the proper commands that allow me to -

Monitor # of files open
Monitor # of pipes open
Monitor Process statistics (ie Proc usage, memory usage).

Hi Scott:

For monitoring open files, use 'fuser' (part of the core Unix command set, or download and install 'lsof':

http://hpux.cs.utah.edu/hppd/hpux/Sysadmin/lsof-4.77/

For monitoring process statistics, use 'glance' if it is installed on your server. You can also use 'ps'. Arm the UNIX95 option and you can create your own list of data to be returned. For instance, to sort processes' memory use in descending amounts:

# UNIX95= ps -e -o vsz -o pid -o args |sort -k1nr | more

Note that a space (blank) follows the equal sign after 'UNIX95'. This sets the variable *only* for the duration of the command line.

See the manpages for 'fuser' and 'ps' for more information. Manpages also come with 'lsof' if you install it.

Lastly, you can find up-to-date, complete manpages along with other documentation here:
