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...

I am trying to get cpu util and memory occupied for a process. I use these (I am showing output also):

Hi ,
we upgarded our AIX from 5.3 to 6.1 and upgraded our xlc compiler from ver 6.0 to 9.0 .
After this upgrade one of our pro*C program is utilizing around 20% of the CPU. Before upgarde its using only 0.2 %.
when i try to debug using the truss command i got the below error.

Hi ,
We need to get the CPU% and Memory utilization of process by process id.
Is there any way to do get them ?
I tried few commands like top -p <PID> ,
but am getting error "Quitting top: pset <PID> doesn't exist"
also i tried with ps -eo option but am getting error "ps: illegal option --... (1 Reply)

Hi,
I am trying to write a script which will fire alert mail to dba ( db2dba) when there process will
utilize CPU more than 90%. But I am unable to do so.
I am using following command to calucate CPU utilization be db2sysc process :
ps -eo pcpu,pid,comm | grep -i db2sysc | awk '{ SUM+=$1;... (0 Replies)

Can someone please help me with a script that will help in identifying the CPU & memory usage by a process name, rather than a process id.This is to primarily analyze the consumption of resources, for performance tweaking.

dapptrace
dapptrace(1m) USER COMMANDS dapptrace(1m)NAME
dapptrace - trace user and library function usage. Uses DTrace.
SYNOPSIS
dapptrace [-acdeFlhoU] [-u lib] { -p PID | command }
DESCRIPTION
dapptrace prints details on user and library function calls. By default it traces user functions only, options can be used to trace library
activity.
Of particular interest is the elapsed times and on cpu times, which can identify both function calls that are slow to complete, and those
which are consuming CPU cycles.
Since this uses DTrace, only users with root privileges can run this command.
OPTIONS -a print all details
-b bufsize
dynamic variable buffer size. Increase this if you notice dynamic variable drop errors. The default is "4m" for 4 megabytes per CPU.
-c print function call counts
-d print relative timestamps, us
-e print elapsed times, us
-F print flow indentation
-l force printing of pid/lwpid per line
-o print on-cpu times, us
-p PID examine this PID
-u lib trace this library instead
-U trace all library and user functions
EXAMPLES
run and examine the "df -h" command,
# dapptrace df -h
examine PID 1871,
# dapptrace -p 1871
print using flow indents,
# dapptrace -Fp 1871
print elapsed and CPU times,
# dapptrace -eop 1871
FIELDS
PID/LWPID
Process ID / Lightweight Process ID
RELATIVE
relative timestamps to the start of the thread, us (microseconds)
ELAPSD elapsed time for this system call, us
CPU on-cpu time for this system call, us
CALL(args)
function call name, with some arguments in hexadecimal
DOCUMENTATION
See the DTraceToolkit for further documentation under the Docs directory. The DTraceToolkit docs may include full worked examples with ver-
bose descriptions explaining the output.
EXIT
dapptrace will run forever until Ctrl-C is hit, or if a command was executed dapptrace will finish when the command ends.
