Script to to find CPU and memory utilization.

Dear Guru's

Server-HP UX IA-11.23

Please help me to find a script to get CPU and memory usage of my server in every 1hr.

I just want to get the utilization value in every 1 Hr, no need to get the high utilization process.


Thanks in Advance!!!!

Hi,

Re: Script to to find CPU and memory utilization.

hi Jeevraj,

If you have OVO monitoring installed, then you can use the following ..

$ /opt/OV/bin/ovcodautil -dumpds SCOPE | grep -i GBL_CPU_UTIL

Re: Script to to find CPU and memory utilization.

# sar -u [interval] [iterations]
(example: sar -u 5 30)
OR

sar -Mu 5 100
(this will produce 100 data points 5 seconds apart.)

%idle This is the percentage of time that the CPU is not running processes.

%usr - user mode Many systems normally operate with 80% of the CPU time spent as user time, and 20% spent as system time.

%sys- system mode

%wio - idle with some process waiting for I/O

Jeevaraj,

Check this out : script : cpumme.sh to get cpu memory utilization over a time,

I have a latest script with swap,raw disk i/o, network usage details and ll upload soon.

Re: Script to to find CPU and memory utilization.

Use 'swapinfo -tm' to get a complete/total picture of swap usage. Pay particular attention to the total line as it indicates how much swap space has been actually reserved for swap. When this percentage gets near 100%, processes will not start up (unable to fork process) and new shared memory segments can not be created.
swapinfo -tm example and explanation :

Mb Mb Mb PCT START/ Mb
TYPE AVAIL USED FREE USED LIMIT RESERVE PRI NAME
dev 288 83 205 29% 0 - 1 /dev/vg00/lvol2
reserve - 141 -141
memory 102 41 61 40%
total 390 265 125 68% - 0 -

o dev line(s):
+ are the actual physical swap device(s)
o reserve line(s)
+ indicate how much of the swap device(s) has(have) been set aside for memory should it need to be swapped.
o memory line:
+ indicative of how much of pseudo-swap has been reserved
o total line:
+ the PCT USED value shown in the total line indicates how much swap space has been actually reserved for swap. When this percentage gets near 100%, processes will not start up (unable to fork process) and new shared memory segments can not be created.
