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

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 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.

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

http://libvirt.org/html/libvirt-libvirt.html#virDomainInfo http://libvirt.org/html/libvirt-libvirt.html#virVcpuInfo Both virDomainInfo and virVcpuInfo have a nanosecond cpuTime field. How do the two related to one another? With some experiementing, it appears the virDomainInfo::cpuTime is equal to the host CPU time used by the qemu-kvm process for the domain. It also appears that the

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 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,all I want to get a relatively accurate cpu usage of a domain. I have a few questions about virDomainGetInfo: struct virDomainInfo{ unsigned char state : //the running state, one of virDomainState unsigned long maxMem :// the maximum memory in KBytes allowed unsigned long memory :// the memory in KBytes used by the domain unsigned short nrVirtCpu :// the number of virtual CPUs for the

Hi Team, I have written below code to get the VM state at run time. I found, though the VM is in shut-off state, when I use the function virDomainGetInfo(); I get state as running. Could you please let me know what wrong I am doing. To know the actual VM state I used 'virsh list' and it clearly shows the VM is in shut-off state. Please find the log and code snippet below. Log from virsh:

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.

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:

Hi All, I am new to libvirt. Please explain about the units (which is bytes or KB or MB) and uses of DomainJobInfo and DomainBlockInfo methods. Like getMemRemaining(), getDataRemaining() etc. Using libvirt version is libvirt-0.5.1. Thank you Regards, Rathidevi

I think this is new since a previous version of R: > h <- function(x, trantab) trantab[x] > w <- 6:4 > names(w) <- c('cat','dog','giraffe') > w cat dog giraffe 6 5 4 > > formals(h) <- list(x=numeric(0), trantab=w) > h function (x = numeric(0), trantab = c(6, 5, 4)) trantab[x] You can see that the names

Hello, I am using dovecot as an imap server, mail is stored in mail directories. Configuration is below. One mail directory has about 14 Gb of mail in the inbox and .Sent directories. Searching from an Android phone with gmail is slow or doesn't work (it times out). Is there a configuration for Dovecot that can improve this? A better e-mail client for Android?

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

Hello, I have the subject mentioned mb and I am trying to install centos 4.4 with sata raid enabled, but linux is not seeing the drives? I tried to load via sata raid driver, no luck there. I guess I could try legacy mode in the bios, but I was hoping there is another way around to load linux with the raid? Thanks....
