bb-iostat.sh?
list David W Gore
We use bb-iostat.sh to monitor some performance stats but I think it may be way outdated and not very accurate for multiple cpu, SAN disk attached Solaris machines. Does anyone have any opinions or a better tool to monitor iostat, swapping etc? I am fairly ignorant about performance measurements and tuning btw except for the basics. ~David

Hi
I'm very interested in the same.
There is some code in the current Xymon but it is broken.
Iostat data is sent (by default) to the server but it is not taken care of properly at the server end.
Some code is there but it lacks the code to put it on pages. If I remember right it is the same xxx.c that add disks.
Someone with some C skills need to make it work.
Search the archive and you find some posts from me that explains more details.
I had a very lame go at the code but couldn't spend the time to learn C again...

For memory, I use http://xymonton.org/doku.php/monitors:memstat For disk stats, I use http://xymonton.org/doku.php/monitors:diskstat.ksh Works for me. YMMV. Regards Vernon On Mon, May 16, 2011 at 5:59 AM, Roland Soderstrom

Then either make the sample time longer, or increase the sample frequency. The former will generate more "average" data. The latter will require some serious modding to your Xymon environment and rrd setup. It's really there only to give an indication of status, for which a short sample will do. A 10 second spike, is not really a problem. Three consecutive spikes would seem to indicate that there is a sustained peak. Possibly a worry? I don't know - depends on your environment. Something you might expect at backup time perhaps? Like all sample tests, it's a sample, which we use to create a model of reality. What is there has been "good enough" for my needs, and has allowed me to do some very important diagnostics and tuning. Feel free to adjust your sample set to suit your needs. Disclaimer - YMMV :-)

My problem with the latter is that it takes a sample, thus the measurements cover only a fraction of the time. In this case it will cover 10 out of every 300 seconds.
