Node.js trace context in queries
Adding trace context to application queries provides the ability to correlate the queries from a traced transaction, and if sampled, the queries to the transaction trace detail. This feature is also a requirement for the integration of APM with DBO.
Enabling
Trace context propagation to queries is disabled by default. It can be enabled in the Node.js Library using this configuration option:
-
insertTraceContextIntoQueries: This option must be set to true.
