Java 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 Java Library using these configuration options:
-
agent.sqlTag: This option must be set to true. -
agent.sqlTagDatabases: This option should be used to restrict context insertion to the database(s) relevant to the instrumented application.
Support Matrix
Trace context is inserted only for statements from a transaction sampled for detailed tracing.
