similar to: Performance measurement using Xenmon

Hi, I am using Xenmon to measure performance of Credit and SEDF schedulers. But as you know, the metrics displayed by xenmon keep refreshing on the screen. When I tried redirecting the xenmon output, I am seeing the attached file. Is there any better way to record results which I can use to draw graphs? Please guide.. Thank you Warm Regards Ananth

Hi, This patch adds the argument check of "--ms_per_sample=" option. For "--ms_per_sample=", a negative value should be invalid. e.g. % xenmon.py -n --ms_per_sample=-1 usage: xenmon.py [options] xenmon.py: error: option --ms_per_sample: invalid negative value: ''-1'' Signed-off-by: KUWAMURA Shin''ya <kuwa@jp.fujitsu.com> -- KUWAMURA

Hi, Can someone clarify for me the numbers that show up in Xenmon? Specifically, I''m curious about the "domain31" entry which always shows up. It looks like this represents the free resources. Also, does anyone know what would happen if more than 30 domain0''s were started (or more likely, I did enough migrations to raise the next domain ID to above 30)? Thanks for

Package: xen-utils-3.0.3-1 Version: 3.0.3-0-2 For some reason, xenmon.py is not in the search path - maybe an issue of the wrapper used by the xen Debian packages seems to be only a link to the wrapper is missing the program exists in the package xen-utils-3.0.3-0-2 and the follwoing make it work: ln -s ../lib/xen-common/bin/xen-utils-wrapper /usr/sbin/xenmon.py ln -s

Hi, I read about RPC interface for xenmon in this presentation: www.xensource.com/files/xs0106_xenmon_brief.pdf Has such interface been implemented yet by anyone?

Hello, When I install guest OS on xen using "xm create /path/of/file/ubuntu.cfg -c" , I am getting an error message *"Error*: Device 0 (*vif*) could not be connected. Hotplug scripts not working <http://markmail.org/message/24aj3qs6ddrtwdks>" . I also saw that hotplugs and udev are prerequisites to be installed before compiling xen. I could not find hotplugs in Yast.

Hi list, I''m working on monitoring CPUs usage per domU, I/O.... using xenmon parsing its output and finally polling the results with cacti. Any advices? If all works OK I will post my work to the list.

In XenMon''s file appending mode, a lot of times I''ll get a strange first data point, e.g., the cpu% for dom0 will be 99.9 but the rest of the readings will be 19-21 which are sane for the run. I''ve been throwing the data point out, but was curious about it. Is it unavoidable? Thanks, Tim _______________________________________________ Xen-devel mailing list

Attached is the second release of XenMon, which is a unique performance monitoring tool for Xen. Instead of using hypervisor calls to get domain information, we use the xentrace facility to provide fine-grained monitoring of various metrics (see README below). We have written up a small case study that demonstrates the usefulness of the tool and the metrics that it reports. This will be

Cycling around many CPUs in XenMon''s curses mode can get cumbersome. This trivial patch adds bindings to move to the previous CPU. The next/previous binding seems more natural to me than the earlier cycle binding, but we can keep them all for now. # HG changeset patch # Node ID 146b5c76086c07fad61bea7ccf60f2f4fd66abbd # Parent 7dd31dbf16e75f0f70e0f9c44b2bb2b5fc6eecf1 Add next/previous

Hi, This patch removes the magic number "31" for readability. The number "31" means the idle domain ID. In detail: - display the idle domain ID with "Idle" instead of "31" - write to the file "log-idle.log" instead of "log-dom31.log".

Hi, Libvirt provides classes such as Xen_ComputerSystem, Xen_Processor etc., in order to build applications using libvirt-api which can interact with the Xen Hypervisor. I would like to know what are the corresponding classes for the KVM hypervisor, so that I can use libvirt-cim to communicate with the hypervisor. Would it be Kvm_ComputerSystem or Qemu_Computersystem? Any help in this regard

I''ve been running any number of CentOS 4 based Xen hosts and guests using CentOS 4.4, and the Xen RPM''s from www.xensource.com, and various hand-built OS images using jailtime and my own own OS images. I like the jailtime approach: One partition for / on the DomU, /dev/sda1, built as a local file or local LVM partition One partiton for swap on the DomU, /dev/sda2,

Package: xen-utils-3.0.3-1 Version: 3.0.3-0-3 Severity: grave Tags: security Justification: user security hole Xen versions 3.x, and 3.1 contain a tool for processing Xen trace buffer information. This tool uses the static file /tmp/xenq-shm insecurely allowing a local user to truncate any local file when xenbaked or xenmon.py are invoked by root. Sample session: # setup. skx

Hi I wanted to instal the exellent DVBviewer application for viewing DVB-T-Television under fedora9 / wine? Under WinXP i need to do the following 3 steps: 1) installing the Driver of my technisat DVB-hardware via the windows control-panel 2) installing the software of my technisat DVB-hardware 3) installing the DVBviewer application. So under fedora9 / wine i don't know to to the first step

I set up a domU as a backup server, but it has very, very poor network performance with external computers. I ran some tests with iperf and found some very weird results. Using iperf, I get these approximate numbers (the left column is the iperf client and the right column is the iperf server): domU --> domU 1.77 Gbits/sec (using 127.0.0.1) domU --> domU 1.85 Gbits/sec (using domU
