Historical data for wireless clients and interfaces is missing

Updated: December 20, 2018


In the Orion Web Console, you cannot see historical data for some wireless clients and wireless interfaces.

In logs, you can find a similar error:

Violation of PRIMARY KEY constraint 'PK_Wireless_Interfaces_DETAIL'. Cannot insert duplicate key in object 'dbo.Wireless_Interfaces_DETAIL'. The duplicate key value is (Dec 01 2018  2:02PM, 431, 1863513).


NPM 12.4


When saving historical data for wireless clients and interfaces, the saving process breaks down.
