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 machin...

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.

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:

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

...ve found so far aren''t so good: 1 - Limit the interface using the XenCenter GUI... but that means the VM would never be able to go above about 1mbps, even if it''s sat there and used no bandwidth for the past week and is well within its quota, so that''s not ideal. 2 - Use sFlow in XCP to capture the data. Well this works for looking at how much bandwidth they are using, but I haven''t found any existing tool that will act on that data to do traffic shaping. 3 - Use the XAPI calls to check the bandwidth usage. With methods 2 and 3 I guess I could write something...

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 Gan...

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 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

...ifferent traffics from the same > box when in need. ntop can read netflow events, the server runs in linux(maybe works in windows too),the client is browser-based so you can access it from almost anywhere.. netflow is somewhat restricted as far as what info you can get, I''ve only used sflow, a brief comparison of the protocols is at the bottom of this pdf: http://www.sflow.org/sFlowOverview.pdf ntop can read sflow as well, though last time I tried it it was unstable, I used sflowtrend instead. nate _______________________________________________ CentOS mailing list CentOS at cent...

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

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 , 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

...lace. 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 & SFlow collector and came across the issue. A quick refresher, the init script for ntop has an issue where it can't parse the ntop.conf file correctly if switches are entered before the "@/etc/ntop.conf". The suggested work around was to move the "-d -L" switches from in front of...

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

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 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.
