I have set up a public service web page at

Have you tried OpenNMS? (opennms.org).

Thanks. Cacti is an improved version also takes feeds and charts
OpenNMS seems to be equivalent to Nagios which I have installed and am
happy with. Nagios was a bit difficult to implement but the Perl-based
architechture made it easier to trouble-shoot.

Another good package which comes with SuSe SLES8 is GNUPLOT.

ANY linux monitor when under z/VM or VMWARE or any other
virtualization are GROSSLY WRONG when you need them most.

that is either aware of this problem or addresses
it. Linux monitors do NOT have the ability to correct this
problem - they are unaware they are virtualized.
They still have some
Interesting. So it seems that if you want to track CPU and memory
performance you have to do it at the aggregate VM level. That makes it
difficult to size the guests. How does one know how much resource to give
to a guest. I do understand that if the guest is under-performing then you
give it some
Sizing is actually pretty easy. What Barton is getting at is that when
Linux reports performance numbers, it does so on the assumption that it
owns the hardware. When running under VM (or LPAR), it doesn't so you
need something that understands VM's influence and can adjust the
numbers that

Or use Barton's ESALPS product, which is designed to do exactly that.

We are looking around for some basic VM performance stats.
We tried grabbing the TRACKZVM VMARC file from
http://sinenomine.net/downloads/trackzvm.php
After installing TRACKZVM and running T we get:
Unsupported CP version z/VM Version 4 Release 4.0, service level 0301

I found some
List Linux Guests
Show Total CPU used %
Show Total Memory used (Real/Paging)

Show Disk I/O rate for a given Disk
IMHO, there's two problems here: capacity planning for real resources

Anybody heard from the Gentoo guys about their S/390 Port?

I have an existing Linux system (non-VM) running SuSE Enterprise Server 8 in

You mentioned that you added the device before extending your volume, but
did you take any steps to ensure that the new dasd is found when the
machine boots?
I use the 'echo add device range=113e /proc/dasd/device' command to
assign another unit to my system
Normally you would add the new
You didn't indicate that you updated your dasd= parameter in your parmfile

That was it. I was really doing two steps.
First, I was adding a new disk to the Linux system, which I failed to do
properly.
And two, I was extending an existing LVM managed filesystems which worked
fine.
I kind of feel like I asked tech support for help and the came by and
