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? I specify all of the host servers as parents of the VM. I reckon that makes perfect sense, and it's dead easy to implement.
