ESX HOSTS MONITORING - ASSET INVENTORY INFORMATIONS

Hello,

I am digging deeply into asset inventory with ESX nodes in ORION. I am exploring database with SQL request:

SELECT * FROM [SolarWinds].[dbo].[AssetInventory_ServerInformation] Where OperatingSystem like '%VMware%'

It is very strange that some ESX hosts have filled in SystemName or  FreeMemoryB and other hosts have SystemName or FreeMemoryB blank. I use for each ones SNMP and VMware Poll throught host directly with local account.

Does have any indea why I have diffrent information in asset inventory foe ESX hosts?

I use SolarWinds Server & Application Monitor 6.3.0
