I'm not sure if the above means anything to the experienced AIX users on here. but the second definition seems suggest the sum of all CPU usages of all process can be used somehow.
I'm trying to monitor the CPU usage of a process and output that value to a file or variable. I know topas or nmon can tell me this in interactive mode but what I need is topas-looking output that allows me to write to a file after a discrete interval. Unlike nmon data collection to a file on top... (5 Replies)
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)
I don't know when the process will start and end, I need write a script to trace it's cpu/memory usage when it is runing. How to write this script? (2 Replies)
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,
I have a multihomed system HP-UX with two NIC cards having IP address 10.9.0.13 & 10.9.0.45
I have two weblogic servers running one listening on "10.9.0.13" and the other on "10.9.0.45"
Given a PID how is it possible to extract the IP Address that the weblogic server is using and... (1 Reply)
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)
hi,
We have two LPARs, both have same capacity and believe same configuration. ulimit settings for oracle user is unlimited for both LPARs. Installed oracle databases with same configurations on both LPARs, both databases sync every second so volume is same. Both LPARs/databases have identical... (10 Replies)

clock
clock(3C) Standard C Library Functions clock(3C)NAME
clock - report CPU time used
SYNOPSIS
#include <time.h>
clock_t clock(void);
DESCRIPTION
The clock() function returns the amount of CPU time (in microseconds) used since the first call to clock() in the calling process. The time
reported is the sum of the user and system times of the calling process and its terminated child processes for which it has executed the
wait(3C) function, the pclose(3C) function, or the system(3C) function.
RETURN VALUES
Dividing the value returned by clock() by the constant CLOCKS_PER_SEC, defined in the <time.h> header, will give the time in seconds. If
the process time used is not available or cannot be represented, clock returns the value (clock_t) -1.
USAGE
The value returned by clock() is defined in microseconds for compatibility with systems that have CPU clocks with much higher resolution.
Because of this, the value returned will wrap around after accumulating only 2147 seconds of CPU time (about 36 minutes).
