SAM / VMAN does "basic" polling of the majority (~40) of our ESXi hosts connected to vCenter but is missing 3. The SolarWinds server can ping those, resolve their hostnames. It does not show them in "Virtualization Summary". The hosts are in vCenter (7.03.01500), with configuration not any different from all the other hosts (a mixture of 6.7, 7.0 and 7.03 ones).
As soon as you've finished adding the vCenter, Hyper-V host, standalone ESX host, or Nutanix cluster, VMAN begins monitoring it.
... yet I am not having such luck. Any idea what I might be doing wrong?
Running SELECT TOP 1000 * FROM [dbo].[VIM_Hosts] in Database Manager doesn't show the missing hosts. They are not anywhere in SolarWinds otherwise (e.g. as ICMP nodes).
(NPM, SAM 2023.1.0 with basic VMAN, polling ESXi hosts via vCenter. No direct ESXi polling.)
