[Nagios-users] ESXi/vCenter Monitoring
Hello all, I have a lot of host servers as VM's on our ESXi infrastructure, managed with vCenter. We also use vSphere DRS to help keep the load on host systems balanced. Due to the DRS, our VM's can sometimes move around from being on one host to being on another w/o my knowledge beforehand. Does anyone know if there is any sort of plugin available for Nagios Core that would basically talk to my vCenter system and find out what VM's are on which hosts, and automatically update that VM's Parent directive in the host definition?

Re: [Nagios-users] ESXi/vCenter Monitoring
check_mk 1.2.3 should do that for you. There's a bit of pain migrating your config into check_mk's WATO, but IMHO it's worth it in the long run. http://mathias-kettner.com/check_mk.html It might be prudent to wait for the check_mk 1.2.3i2 before playing with it, though.

Re: [Nagios-users] ESXi/vCenter Monitoring
Hi Daniel, We monitor our VM servers with Nagios but point to their IP addresses in the hosts.cfg. Since these don't change and Nagios doesn't care what VM host the server is running it is not a problem. We make the network switch the parent, not the VMware host. -- Martin T.

Check_cluster aggregates the status of individual ESX hosts. The clusters here have three or four ESX hosts each. If one ESX host in the cluster is offline, my check_cluster returns a warning. If all but one are offline, I have it return a critical. At that point, the engineers have more important things to worry about than individual guests. I have a fake host for each cluster whose check_host_alive is the check_cluster command. The guest VMs on each cluster have the fake host set as their parent. The guests can move around all they want and I don't have to change anything. When the engineers change the clusters by adding or removing ESX hosts, all I have to do is add or remove one ESX host check and update the check_cluster command. I don't have to edit the list of parents for all the guest VMs, which is important, because we have more than a thousand of them. -- -Chris -- Get 100% visibility into Java/.NET code with AppDynamics Lite!
