A useful monitoring object is total available memory
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)
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
or
I think in HP-UX 11.x the best command to determine the logical CPUs is

drawterm
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.
