The topas tool is a full-screen tool and its output is not well suited for filtering it in a pipeline. I suggest you use vmstat instead, which presents the same information (albeit in different form, but well suited for filtering).
I hope this helps.

seeing weirdness across some 7.1.5.1 LPARs - they all have 2 vCPUs allocated shared. With prtconf they show 2 CPUs, 'lsdev -c processor' concurs, and 'lsattr -El procX' shows that SMT is enabled and there are 2 SMT threads (power5, sorry). Yet running topas on them shows 2 CPUs on some and 4 on... (3 Replies)

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.
