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, 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 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.

Hello, Recently I''ve received some complaints that there is excessive but intermittent latency of network traffic to domUs on some of my servers. Upon investigation it seems that on some servers, indeed traffic is occasionally delayed by up to 140ms where something like 5ms RTT would be expected. The average RTT is not unusual; since this is only occasional packets it only affects the

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

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, 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 have two KVM guests in ubuntu host machine.I am using Python binding of Libvirt API to query on the hypervisor and capture the CPU , memory related information of the guest machines. I need to capture the detail information regarding CPU like : cpu_aidle, cpu_idle, cpu_speed, cpu_wio and memory like :mem_cached,mem_buffers,mem_free etc. of the guest machines. How could I get these

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

I don't know why I haven't signed up for this list before since we use CentOS all over the place. The list is very useful and it is good for me to participate and "give back" to the community. Anywho, I wanted to post this response to a thread that was created back in November 2008 about the ntop daemon failing to start. I'm currently setting up ntop as a NetFlow &

Hi all, is it possible to monitor guest's interface's stat which uses SR-IOV virtual function? I don't know how qemu/libvirt implement monitoring, if functions like interfaceStats are implemented in the host, I think there's little chance to do this due to SR-IOV's nature, is it right? If i can't use libvirt to monitor SR-IOV interfaces, is there another way to do

Hi, I have a router running BGP and OSPF (bird) on FreeBSD. Are there any best practises one can take in order to protect the network from DDoS attacks. I know this isn't easy. But I would like to secure my network as much as possible. Even if I'am not able to prevent or block a ddos I would like to get some info (snmp trap parhaps) regarding the attack. Then I can contact my ISP or

Dear all, I want my container to run on the third CPU core and I define this by the following xml scrpits: <vcpu placement="static" cpuset="3">1</vcpu> When I run my application in a container terminal, I can see the application runs on the third core as expected. When I run my application using lxc-enter-namespace, the CPU pinning doesn't take effect, i.e.,

Hi all, I need to setup a netflow reporting tool under CentOS server to collect traffic data from several firewalls. What netflow tool do you recommends me? Of course, Open source.

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.

Hi guys , Im have some problems installing the following packages: rrdtool-devel rrdtool-perl Before we moved to centos/rhel7 it was a simple task, just doing: yum install rrdtool rrdtool-devel and rrdtool-perl was enough. Now, I only can install the rrdtool package but not rrdtool-devel and rrdtool-perl. I tryed adding some repos, but I think I added wrong ones. Also tryed downloading and
