I created a fake host (with IP 0.0.0.0) for the cluster with active checks and notifications disabled. This way I have one and the same parent for all VM's in that cluster. Let me show it this way: switch ---> esx1------------> VM-CLUSTER-1 ----------> VM1 | ------------> esx2------------> | --------------------------------> VM2 | ------------> esx3------------> | --------------------------------> VM3 | ------------> esx4------------> |---------------------------------> VM4 I hope you see what I'm trying to show. In text: Parent of vm's 1-4 is the 'fake' host VM-CLUSTER-1. Parents of VM-CLUSTER-1 are esx1, esx2, esx3, esx4. Parent of esx1-4 is switch. Positive: You can represent the cluster with a host and in the map it's clearly seen which physical hosts are part of this cluster. Negative: The host will stay "grey" (pending) in Nagios as no check will be executed on the fake host. In Nagvis it looks good and it makes sense. <div class="gmail_quote">On Tue, Jan 3, 2012 at 10:51 PM, Jim Avery <<a href="mailto:jim@jimavery.me.uk">jim@jimavery.me.uk</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div class="im">On 3 January 2012 20:58, alexus <<a href="mailto:alexus@gmail.com">alexus@gmail.com</a>> wrote: > I have few hyper-visors that running bunch of VMs. Each VM runs on a > HV and can be migrated from one host to another at any given time for > whatever reason(s). > Should I specify all HVs (where VM can run) for each VM as a parent? </div>That's what I do, yes. <div class="HOEnZb"><div class="h5"> ------------------------------------------------------------------------------ Write once.
