similar to: How are you measuring CPU usage?

Hi, I am trying to create a report across all my KVM hypervisors using libvirt API and I need some assistance in figuring out the right API calls. My report will contain the total available memory, CPU, disk across all hypervisors, versus the amount used by the virtual machines. This report will help figure out if we are running low on hypervisor disk, CPU or memory and if we need to add more. I

Hi Guy, I am trying to figure out how & where can i get the bandwidth usage utilization statistic info for all the VM, so in the end i will be able to use it for metering purpose.. Anyone got any idea ? Regards, Peter -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi folks, is it possible to monitor and gather statistics in realtime (CPU, memory, HDD, network, ... - something like dstat) of guest systems with libvirt through console from host system (KVM based)? If yes, do those guests need to be created through libvirt? Thanks for your help and time.

If you need to continuously track libvirt metrics, you might want to install Host sFlow agents on each of your KVM hypervisors: http://host-sflow.sourceforge.net/ The Host sFlow agent is a lightweight daemon that links to the libvirt library on the hypervisor and sends hypervisor and VM metrics using the sFlow protocol to a central collector. You could use an sFlow analyzer like Ganglia to

Hi Guys I''m trying to measure the traffic of domUs using vnstat without luck. My configuration: Debian 6.0.3 xen 4.0.1 vnstat 1.11 I''m using bonding with two network cards. auto bond0 iface bond0 inet manual slaves eth0 eth1 bond-mode active-backup bond-miimon 100 bond-updelay 200 bond-downdelay 200 bond-primary eth0 auto br0 iface br0 inet static

Would it be possible to list the Host sFlow project in the Monitoring section of http://libvirt.org/apps.html? Host sFlow <http://host-sflow.sourceforge.net/> Host sFlow is a light weight agent running on KVM hypervisors that links to libvirt library and exports standardized cpu, memory, network and disk metrics for all virtual machines using sFlow protocol. Thanks, Peter

Hi all, I''ve got XCP 1.0 up and running nicely and would like to use it in production. However I''m struggling with the concept of bandwidth management. It seems like such a common problem that everyone must have, but I can''t find any clear direction in which to go. The dedicated host I am using (Hetzner) gives me a 5TB monthly bandwidth quota which needs to be shared

Hi, I have noticed that virt-manager has the ability to show me the current cpu- and memory-usage of both the host and running guest machines. How does it do that? I could make good use of that information myself in the client applications I'm writing, however, from what I can see on http://libvirt.org/html/libvirt-libvirt.html, I have no idea how to go about getting it from libvirt. In

Hi I seem to be having a little trouble with libxenstat, and was wondering if the xenstat guys might be able to help. I''ve pulled the xen-unstable.hg tree and done a somewhat clean install (ie, post-make uninstall, as well as deleting the relevant libxenstat libraries). Next, I entered the tools/xenstat/libxenstat directory and modified the Makefile so that the shared libraries would

Hi All, What is the best way to remotely monitor/administer a group of xen domUs across a network? We''re planning to deploy a few H/W servers with paravirtualized domUs. What are the best alternatives? What works and What doesn''t? Share your experiences.

Hello all: Is there a network switch that will give me traffic stats at an IP address level? Right now, I only get statstics at a port level, but that does not help since each of my servers run several virtual machines and I need to measure traffic per virtual machine.

Hello All, As I''m going to write some kind of a monitoring sensor, which will use the same information "xentop" currently provides, I would like to know if libxenstat can be considered as stable? Will libxenstat be supported in future versions of Xen? Or is it rather advisable to get this information from the Xen Management API, which maybe provide the same data? The sensor

Hi I am using xen4.0.3 in Opensuse11.4. I need to do the monitoring of VM''s and on that basis take the migration decision so I am trying to write my own xentop like program. But I am facing trouble while using xenstat.h in my C program. test.c:3:24: fatal error: xenstat.h: No such file or directory But my xentop is working fine. What to do in this case. How to use libxenstat library in my

What is the best way to monitor the total incoming / outcoming network traffic of CentOS server. I think that the solution is to monitor the network interfaces and to send SNMP packets to remote server. But is it possible? regards -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hello, I noticed that the CPU% reported by xentop appears to be too high. With dom0 idle xentop is reporting between 14-17% CPU utilization while at the same time top in dom0 is reporting 1-4% CPU utilization. I see that the TODO for xentop includes a task to make CPU% more accurate but looking at the code for xentop and libxenstat I''m not sure how to go about this. Assuming the CPU

hello list, I'm trying to install ganglia-gmetad on centos 5.6. rrdtool is already installed and librrd is there. But for some reason when I go to install this package it doesn't see that it is.

Hi folks Some proposed changes: * Fixiate the API/ABI of some libs, for the stable version, including - libxenctrl, - libxenstat, - libxenstore. As upstream don't know what abinames are for, roll own abinames. * Add libxenctrlX, libxenstatX, libxenstoreX, if abinames may be different or libxenX if the abinames should the same for all libs. * Add libxen-dev including - static

When xenstat library parse /proc/net/dev, it uses strpbrk function to get pointer to device name. However, it miss capital letters in the array of valid characters so it get incorrect name in case device name starts with capital letters or even segfault if it contains only capital letters. This patch adds missing characters to strpbrk call. Signed-off-by: Miroslav Rezanina

Hi All, is there any tools/mods for apache2 which are you using to monitor the load of every virtual host? (e.g. mod_proctitle) thanks -- Sergey Smirnov email/xmpp: Sergey.A.Smirnov at Gmail.com
