Re: zLinux CPU monitoring

Mark- I'm sure we can help you understand the benefits of integrating OMEGAMON in the z/VM environment to provide a complete monitoring solution across the enterprise and provide complete end-to-end capabilities. Full disclosure: IBM is my employer. zNorman -Original Message- From: Linux

zLinux CPU monitoring

Hello, This is probably an old already well digested topic, but is there any reliable way to monitor CPU usage on Linux level? Linux tools like TOP and SAR seems to show z/VM's cap as a maximum in their statistics eg. share is set to 4% per IFL --> 2xIFL is 8%. This is ok from providers point

Re: zLinux CPU monitoring

There is a GSE conference for Linux, z/VM and z/VSE in Stuttgart Germany in 3 weeks. That same week, there is a performance class that will show how to get exactly what you want using zVPS "http://velocitysoftware.com/zvps.html;. If you care about performance of Linux under z/VM, you need the

Re: zLinux CPU monitoring

VMCP IND? (I don't have VM in front of me...) And top does actually show %STEAL on zVM, so that’s useful too. Jon -Original Message- From: Linux on 390 Port [mailto:LINUX-390@VM.MARIST.EDU] On Behalf Of Mikael Wargh Sent: Wednesday, September 30, 2015 3:45 AM To:

Re: zLinux CPU monitoring

I was once researching something similar (i.e. how to get reliable CPU readings from within Linux) but unfortunately never finished. But I still have the links, maybe you will find something interesting there: Presentation about how Linux kernel can get accurate CPU readings from the

SLES12 + EDEV + bug

I think I might have found a small bug in latest update for SLES12 so this is just a FYI for everyone who made the same mistake I did. If you use edevices, you know that the FBA driver in linux automagically (like Mark explained it to me few years ago ;) ) creates a device “1” (dasda1 for

Re: zLinux CPU monitoring

This was good information, many thanks Tomas! As we're going more open with LinuxOne, KVM and probably more to come, I really think that at least the basic monitoring should have several options to choose from. In traditional x86 Linux world the performance monitoring sector is flooded by

Hello, all. I now have the zKVM DVD 1.1 here. Where can I find the installation/configuration doc for it? Thanks and have a good one, too. DJ On 09/24/2015 02:51 AM, Christian Borntraeger wrote: > > z/VM does call SIE on behalf of the guest hypervisor. So for CPU bound > workload, which
