Monitor CPU usage over a period of time.

[CJENSEN_1]

Hello Everyone,
Is there an easy way to monitor CPU usage over the course of an 8hour day? IE - is there anything else other than sar or top that is within HPUX 11.11? This is on a RP5470 server.
Thanks,

Easy way is a) Glance and b) Perfview. Glance is good at giving you the "right now" picture. Perfview will give you the view over time - comparing days to days etc, over a large time over many variables. Both must be purchased from HP. A free trial of Glance is on your installation CD's. You could call your HP salesman for a trial eval period of Perfview, and I'm sure they'd grant it.

PerfView for viewing trend attributes over a period of time.

Glance is "real-time"

top is real time.

sar lets you specify time length and the time increments, if you want to collect every 15 min or every 30 min.

Hi

As the previous reply said PerfView is only fore viewing the stats. MeasureWare or PerformanceAgent actually logs the data.. This data can then be viewed by PerfView, or you can output it into ASCII & importv into MS Excel.

To install MeasureWare you actually install GlancePlus PAK... The PAK bit is important, as it contains the measureware software. If you install GlancePlus you ONLY get glance... Ive come across quite a few servers where people say I have Glance, therefor I have measureware.. this is not so.

You can use sar in a script and call the script though cron every few minutes and appeed the output to a file

for CPU
eg. sar -u >> /{dir}/cpu_filename
for multiporocessor activity
eg. sar -M >> /{dir}/multi_cpu_filename

thanks

I have a script that runs about every 15 minutes
from cron taking snap shots the are very involved but a simple example is as follows

vmstat |grep -v o >> logfile

that the letter o in grep (it removes the headers)

the output is one line record. you are intereted in the CPU IDLE colume (man vmstat)

I put a header in logfile and have them named
vm01, vm02 ...vm31 so I can track cpu swaping etc for the last 31 days. do montly summary
Got examples for O'Reilly System Performance Tuning (pub Dec 1992).
You can do something similar with "uptime"

Attaching a full range of sar scripts:

Can be run for any length of time.

you can use sar utility. add it in to crontab and get it executed every 1 minute or so. it collects the statistics and stores it in /var/log/ directory

PerfView would be the best solution
