I'm using SQL query to search connected devices: Re: UDT SQL Query: Get user device switch by MAC or host name
We are using 10 min polling time for UDT.
I used where clause to pick only direct connections (Orion.UDT.PortToEndpointCurrent table, row ConnectionType as 1).
After using it while, I noticed that update of ConnectionType takes about 30 minutes.
When I dropped clause away, I found that after UDT polls network device, newly connected device has empty ConnectionType.
After approx 20min ConnectionType was updated to 1.
What happens during this 20 min timespan and what causes this delay to update ConnectionType?
