Performance

[Kevin Daines]

We are running HP-UX with 2GB RAM and 100GB disk space. I have recently done the first HP-UX system administrators course, and I find I am still lacking in the knowledge I need to diagonse performance issues. I can use 'top' and 'sam' to look over the general system properties, but are there any tools for things like disk I/O? Can anyone recommend a course which covers these issues?

Kind Regards
Kevin

Look at sar, in particular sar -d

Hi Kevin,

In addition to sar, look at iostat and vmstat.

Hi Kevin,

In addition to course work, there are a lot of good white papers available that discuss HP-UX performance tuning. Here is a link to one of the more popular ones:

Hope this helps,

In addition to the defacto tools mentioned above, look into MRTG and RRDTool. Both are great utilities, and RRDTool can be setup to monitor just about anything.

Hi

You can use
#sar -d 1 5
iostat -t 1 5
or glance (You will have to purchase ;not a part of core os installation package)

Hi Kevin

In addition to the whitepapers, there is an excellent book on HP-UX performance tuning that has been published.
This is an excellent resource for understanding HP-UX performance.
