Spring Boot GraphQL Tutorial #24 - Instrumentation (Request Logging)
GraphQL Instrumentation allows you to inject code that can observe the execution of a query and also change the runtime behaviour. Let's take advantage of this to log the graphql request's query, variables, any exceptions thrown and execution time.
To do this we create a spring bean of type graphql.execution.instrumentation.Instrumentation.
To remove boilerplace no-op code, we override no-op SimpleInstrumentation implementation and just override the beginExecution method.
We then return a SimpleInstrumentationContext with an whenCompleted callable containing our duration logic and log message.
It is possible that multiple Instrumentation objects are in one graphql server.
In the next video, I demo the TracingInstrumentation that will capture the execution time of the fields and place the results into the graphql response.
See you in the next video!
Cheers!
