QueryTrace

After being executed, it retrieves the trace of the CQL query.

Use EnableTracing(Boolean) to enable tracing.

Note that enabling query trace introduces server-side overhead by storing request information, so it's recommended that you only enable query tracing when trying to identify possible issues / debugging.
