Monitor CPU/Mem Utilization on HP-UX

[Michael Thomas_1]

Anyone have any suggestions on a "QUIK" way to log Memory and CPU Utilization on a N4000 running HP-UX-11i????

MWA measureware is the best tools to log the system utilization.

The various options for sar will track the information and you can have sar create logs. However, HP-UX memory and CPU usage is not going to be very useful as far as capacity and performance. HP-UX is a virtual memory system so true usable memory is measured by swapinfo, and undersized RAM is measured by vmstat, specifically the po column. CPU usage is completely driven by the applications, some may use all of the CPU and be normal.

Hi,

You have SAR to log the CPU utilization and as far as memory is concerned, you can setup a cron job using vmstat to capture the virtual memory activity along with the swapinfo ouput.

Hmnnn...you could use top - redircet to a file...

Quick and dirty:

#!/bin/sh
cat top.txt >> top.save.txt
top -f > top.txt

Then run it from cron every 5 minutes?

Also look at sar as others have suggested...
From cron:
# SAR
#0 * * * 0,6 /usr/lib/sa/sa1
#0 5-19 * * 1-5 /usr/lib/sa/sa1 1200 3
#0 20-4 * * 1-5 /usr/lib/sa/sa1
#5 19 * * 1-5 /usr/lib/sa/sa2 -s 5:00 -e 19:00 -i 3600 -A
0 * * * 0-6 /usr/lib/sa/sa1
10,20,30,40,50 5-19 * * 1-5 /usr/lib/sa/sa1
5 18 * * 1-5 /usr/lib/sa/sa2 -s 5:00 -e 19:01 -i 600 -A


Better to have measureware/perfview (extra cost) installed...
