logging processes

James Grice — Thu, 25 Oct 2001 17:47:00 GMT

Can anyone tell me if there's a way to log the top 5 or 10 processes ? Is there a product that can be purchased? Here's HP's reply :

As I understand it from the case notes, the customer is looking for a method to take a snapshot of the top ten or so processes at a settable interval. The following may meet their needs.

If I were collecting this data, I'd use the undocumented "-f" option of top(1), along with the "-d" flag. I'd set up a cron job to run every 5 minutes and execute this command:

/usr/bin/top -n 10 -f /path/filename

The "-n" flag specifies the number of processes you wish to see, sorted by CPU utilization. The "-f" flag specifies the pathname you want the results printed to, but also specifies that you want just a single snapshot. The file will not contain the cursor control characters you'd have if you redirected top's output to a file using ">". And if top finds the file already there (as it would, in this case), it will append to it. Thanks in advance-Peace

Hi,

If you have perfview then it is easy to get the report from measureware agent you can collect data.

Also set cron for sar regular interval.

GoodLuck

Hi James:

For ad hoc, short periods, I don't see anything particularly bad about this response. For long-term serious performance analysis, I'd look at Glance/Measureware or somthing like it.

Regards!

I have used that top functionality before and have had no problem,s. For more detailed/refined reports you might want to set up a glance advisor which generates teh report that you wish.

Measureware is a great tool that I have been getting familiar with. You will be able to not only extract current performance data, but historical as well. Perfview is a separate product all together, but allows you to create graphs of metrics without having to ftp the data file to a pc an use excel. You can also centrally manage data collection from a single server with Perfview.

Hope this helps
Chris

James,

I've attached a Glance Adviser Syntax example. You can save it to a file in your current directory. Let's say we call it top5.syntax. Then you can run something like:

glance -adviser_only -syntax top5.syntax -j10

I hope this helps ... Mladen

James,

The top command should do
fine ,except that i have
found top to be off-mark
on odd occasions.

Glance is a good alternative.
