We have a compliacated DMZ setup where my polling engine is unable to access individual ESXi hosts, however it has access to our VirtualCenter server using an account which has the correct permissions to monitor specific clusters. I have this imported into SolarWinds and all looked fine, however because my poller has no access to the hosts when I imported the ESXi servers I had to set them as external. This appears to have frozen all data relating to the host servers whereas that data should be polled via the VirtualCenter server? It's not updating the ESXi hardware status, the virtual machine info etc etc that all appears to be static? Any idea how to get around this? Because the hosts are being polled from VirtualCenter I should not have to set them as external - it should just know to get their status from the management environment? Thanks Mike
