I am trying to figure out how to monitor XEN. I use cacti for graph pretty much all my servers. But XEN will start to monitor now. I have some questions about it. How do i get the CPU load on Dom0 like, the really CPU use ? barematel cpu i guess. I supose that snmp will give me the interface traffic ok. Some how to monitor IO/wait of Dom0 I want to graph all stuff on Dom0 like the sum of each virtual machine in vms. Does any one can help ? Thnaks! I am new at Xen, i just got someone else work. He left the company and now i have to take care of Xen. Hope you guys understad that i am new and does not know much xen.

Henrique, You might want to take a look at Host sFlow: http://host-sflow.sourceforge.net/ The agent is installed on Dom0 and will report on Dom0 performance as well as statistics for each virtual machine. Are you planning to use the Open vSwitch? The Open vSwitch is part of the Xen Cloud Platform (XCP) and includes sFlow to provide detailed visibility into inter-VM network traffic as well as exporting vNIC interface counters. SNMP polling doesn''t work very well in dynamic environments where virtual machines may be frequently created, destroyed or migrated. The sFlow protocol uses a push model instead, making it extremely scalable and very responsive to changing configurations. Have you considered using Ganglia for monitoring your XEN servers? Ganglia was designed to monitor clusters and grids and deals with large server pools very well. The current development branch of Ganglia (trunk) supports sFlow: http://blog.sflow.com/2010/10/ganglia.html Peter On Mon, Feb 14, 2011 at 7:59 AM, Henrique Fernandes <sf.rique@gmail.com> wrote:> I am trying to figure out how to monitor XEN. > > I use cacti for graph pretty much all my servers. > > But XEN will start to monitor now. > > I have some questions about it. > > How do i get the CPU load on Dom0 like, the really CPU use ? barematel cpu i > guess. > > I supose that snmp will give me the interface traffic ok. > > Some how to monitor IO/wait of Dom0 > > I want to graph all stuff on Dom0 like the sum of each virtual machine in > vms. > > Does any one can help ? > > Thnaks! > > I am new at Xen, i just got someone else work.
