We're using Opentracing/Jaeger in Istio for tracing multiple Spring Boot/Spring Cloud based microservices.
I'm currently wondering if there's an option to enrich the tracing spans by providing information about executed query (i.e. SQL statement)? Tracing JDBC connection info is working fine using opentracing-contrib/java-spring-cloud but additional information is missing.
I know that e.g. glowroot is capable of tracing the statements itself but haven't found anything related to Opentracing or Jaeger.
Would be great if anybody could show some directions for research!
