Pretty print JSON output of Spring Boot Actuator endpoints

Question

Spring Boot Actuator provides several endpoints to monitor an application as:

/metrics
/b         


        

Answer 1

With spring-boot 1.2.6, you need to use:

spring.jackson.serialization.INDENT_OUTPUT=true

From my log when using the old http.mappers.*:

http.mappers.json-pretty-print is deprecated. If you are using Jackson, spring.jackson.serialization.INDENT_OUTPUT=true should be used instead.
