I'm trying to create a script to catch a process which is consuming high CPU which I have pretty much done but it's just finding the correct place to pull the current CPU for that process.
When viewed in Topas it's consuming 99.*% cpu
But if I try using
it shows as only consuing 9.*%.
is there another command that would reflect the figure in topas?
Hello All,
I wanna find the CPU utilization of a specific process running on AIX OS. I have its pid, but not sure about the command.
iostat
sar 5 5
vmstat
All the above give me system CPU utilization. Is there a way to find for a specific pid???
Thanks,

hi,
i want to know cpu utilizatiion per process per cpu..for single processor also if multicore in linux ..to use these values in shell script to kill processes exceeding cpu utilization.ps (pcpu) command does not give exact values..top does not give persistant values..psstat,vmstat..does njot...

Hi.
I am looking for a command that will return me the amount of CPU used by a specific process in AIX environment.

Hi,
may be this is an AIX noob question:
my current C++ application runs on Linux and is quite memory consuming. Therefore, the application writes a logfile after it has finished containing memory information, CPU information, information on the running other processes besides my application... (0 Replies)

I've been more used to Solaris, but am now working on an IBM AIX box, P650
Certain commands like "top" are no longer available. Any ideas on where I can find help on this matter?

OS: AIX
so we frequently receive a lot of cpu related alerts. all types of checks have been created to keep an eye on the cpu but a lot of these checks make too much noise as the CPU is always being seen as high. the system and application owners say there's no issue with the cpu.
so now,... (6 Replies)

trafgen(8) netsniff-ng-toolkit trafgen(8)NAME
trafgen - a high-performance zero-copy network packet generator
SYNOPSIS
trafgen [-d|--dev <netdev>][-c|--conf <file>][-J|--jumbo-support] [-x|--interactive][-n|--num <uint>][-r|--rand][-t|--gap <usec>]
[-S|--ring-size <size>][-k|--kernel-pull <usec>][-b|--bind-cpu <cpu>] [-B|--unbind-cpu
<cpu>][-H|--prio-high][-Q|--notouch-irq][-v|--version] [-h|--help]
DESCRIPTION
A high-performance network traffic generator that uses the zero-copy TX_RING for network I/O. For instance, on comodity Gigabit hardware up
to 1,488,095 pps 64 Byte pps have been achieved with trafgen.
OPTIONS
trafgen --dev eth0 --conf trafgen.txf --bind-cpu 0
Use packet configuration trafgen.txf, eth0 as transmission device and CPU0 for binding the process.
OPTIONS
-h|--help
Print help text and lists all options.
-v|--version
Print version.
-d|--dev <netdev>
Device for transmission i.e., eth0.
-c|--conf <conf>
Path to packet configuration file.
-x|--interactive
Start trafgen in interactive mode.
-J|--jumbo-support
Support for 64KB Super Jumbo Frames
-n|--num <uint>
Number of packets to generate before exiting. 0 means forever until SIGINT.
-r|--rand
Randomize packet selection process instead of round-robin.
-t|--gap <uint>
Interpacket gap in microseconds.
-S|--ring-size <size>
Manually set ring size to <size>: mmap space in KB/MB/GB.
-k|--kernel-pull <uint>
Kernel pull from user interval in microseconds. Default value is 10 microseconds.
-b|--bind-cpu <cpu>
Bind to specific CPU (or CPU-range).
-B|--unbind-cpu <cpu>
Forbid to use specific CPU (or CPU-range).
-H|--prio-high
Make this high priority process.
-Q|--notouch-irq
Do not touch IRQ CPU affinity of NIC.
EXAMPLES
Generate traffic defined in trafgen.txf on eth0 using CPU 0
trafgen --dev eth0 --conf trafgen.txf --bind-cpu 0
Generate traffic on eth0 using CPU 0, wait 100 us between packets
trafgen --dev eth0 --conf trafgen.txf --bind-cpu 0 --gap 100
Generate 100,000 packet on eth0 using CPU 0
trafgen --dev eth0 --conf trafgen.txf --bind-cpu 0 --num 100000
