Operating Systems HP-UX How to find the used memory in HP-UX? Post 302935679 by MadeInGermany on Wednesday 18th of February 2015 01:38:55 PM

A useful monitoring object is total available memory
Code:
swapinfo | awk '{total+=$2; used+=$3} END {print int(used*100/total)}'

And a warning threshold of 80 (percent usage).
This will warn before an "out of memory" situation occurs. It does not say anything about system performance.
Regarding CPU, a useful monitoring object is system load (obtained from the uptime command)
Code:
uptime | tr -d ',' | awk '
{
 v1=$(NF-2)/cores; v2=$(NF-1)/cores; v3=$NF/cores
 msg=sprintf ("- load average: %4.2f, %4.2f, %4.2f",v1,v2,v3)
}
(v1>w && v2>w && v3>w) { print "WARNING",msg; exit 1 }
{ print "OK",msg; exit 0 }
' w=1.1 cores=2

Best practice is an AND condition of (1min average, 5min average, 15min average) as done with awk,
and a threshold of 1.1 if the load is divided by the number of active virtual CPUs (here "cores" is set to 2).
Where the number of "cores" can be determined on HP-UX with
Code:
machinfo

or
Code:
top

I think in HP-UX 11.x the best command to determine the logical CPUs is
Code:
/usr/sbin/ioscan -k -C processor | grep -c '^[0-9]'

DRAWTERM(1)						      General Commands Manual						       DRAWTERM(1)

NAME
drawterm - connect to Plan 9 CPU servers from other operating systems SYNOPSIS
drawterm [-d] [-a authserver] [-c cpuserver] [-e encription_hash_algs] [-k keyspec] [-s secstoreserver] [-u username] [-C command args ...] DESCRIPTION
drawterm is not a Plan 9 program. It is a program that users of non-Plan 9 systems can use to establish graphical cpu(1) connections with Plan 9 CPU servers. Just as a real Plan 9 terminal does, a drawterm serves its local name space as well as some devices (the keyboard, mouse, and screen) to a remote CPU server, which mounts this name space on /mnt/term and starts a shell. Typically, either explicitly or via the profile, one uses the shell to start rio(1). By default, drawterm uses the CPU server $cpu or cpu, and the authentication server $auth or auth, OPTIONS
This program follows the syntax of the cpu(1) Plan 9 command. A summary of options is included below. -h Show summary of options. -a Specifies the authentication server to use. If not present uses the $auth environment variable, if present, or tries with a host name of auth. -c Specifies the cpu server to use. If not present uses the $cpu environment variable, if present, or tries with a host name of cpu. -u Specifies the username to authenticate with. If not present uses the $USER environment variable, if present, or asks interactively for an username. -s Specifies the secstore server to use. -C Specifies a command to be executed remotely. -e,-k Allow for selecting the hash algorithm and keys used, they have the same meaning as in cpu(1). SOURCE
In Plan 9 distributions, /sys/src/cmd/unix/drawterm. DIAGNOSTICS
Drawterm prints most diagnostics in its own window. BUGS
Although at first drawterm may seem like a Plan 9 terminal, in fact it is just a way to provide a CPU server with some terminal devices. The difference is important because one cannot run terminal-resident programs when using drawterm. The illusion can be improved by deli- cate adjustments in /usr/$user/lib/profile. Should import latest /dev/draw to allow resize of window Should copy 9term code and make console window a real 9term window instead. Should implement /dev/label. SEE ALSO
