A datastore heartbeat and a VM Tools heartbeat are two completely different things. They do share the same name though, which I concede can be confusing. The datastore heartbeat in that image is simply a way for the HA node to determine if it's isolated from other hosts when the management network is down. If that is not checked, HA will not have that additional mechanism to determine the host state (partitioned, isolated, or failed) The VM Tools heartbeat is something different and when OS monitoring is enabled it looks for I/O on the actual VMDK for that VM. It has nothing to do with the datastore heartbeat selected.
