The unclassified traffic in the web console has been identified as MSSQL traffic.

Comprehensive and Detailed Explanation From Exact Extract:

A. A different port is being used: If MSSQL traffic is sent on a port different from the default (1433), SolarWinds may not classify it as MSSQL unless custom mapping is defined.

C. The source or the destination port field is not present: Application mapping relies on port information; missing fields prevent classification.

The documentation states:

"Unclassified traffic may result when known applications use non-default ports or when flow records lack required port information for mapping."
