I am trying to monitor a remote VMware host and am having some issues. The services for the host are monitoring properly and are in an Up state, but the state for the host itself is Down. I have several local VMware hosts which I am monitoring without this issue so I suspect it is due to a port on the firewall being blocked. I have opened ports 22, 5666, 5667, and 12489 on both ends. This has gotten me to the stage I am at, with only the services being monitored successfully.

Any help or guidance is much appreciated.
Thanks

The keep_host_alive check is an icmp echo [ping] check. If your firewall blocks echo requests, the box will not respond to pings. Can you ping the VMWare server in question from the XI box?

EDIT: port 7 is for the "old" echo requests. ICMP runs on layer 3, not 4, so icmp would have to be specifically blocked by your firewall.
