In ksh
tells you the percentage of time the process has used the CPU since the process started.
Thanks but that unfortunately doesn't give the actual current %CPU usage. Its also further diluted by the number of available processors. So while what you suggest may give a value of 0.6% the actually current usage could be 35%. I've seen this in practice and thats my dilema.
Hi,
I am designing a load balancer for an application. I am trying to find out the CPU usage by a specifc Unix process (PID is known). I guess I can use ps command to find that. can somebody help me in finding what exact command I should use to find? It is on AIX 5.3.

Hi,
I have a shell script. But, upon execution of the same, the cpu usage is sometimes getting 100 % (checked executing top command).
At that point of time, my process hangs, doesn't run anymore. I need to kill it manually.
My concern is, is there any default method, by which I can check... (1 Reply)
Hi,
By using time command we can determine the execution time of a process or command.
bash-2.04$ time ls -l
total 0

Hi guys,
I am currently writing a JAVA script to monitor certain unix processes through JConsole.
Upon having lots of trouble with runtime.exec, i decided to bypass the top/ps command call and just get the information straight from /proc/*pid*/whatever.
Now i can pull back any... (0 Replies)
Hi all,
I am currently having trouble to get nmon to print me the actual CPU usage for an interval for a process.
According to the manual, something like
# time nmon -t -C cron -s 5 -c 2 -F outfile
real 0m0.98s
user 0m0.03s
sys 0m0.04s
should print out at least the process... (15 Replies)
Hi,
I will be creating a process myself and I want to know the average CPU and RAM used by the process over the lifetime of the process. I see that there are various tools available(pidstat) for doing , I was wondering if it possible to do it in a single command while creation.
Thanks in... (3 Replies)
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)
