Common application properties

Various properties can be specified inside your application.properties file, inside your application.yml file, or as command line switches. This appendix provides a list of common Spring Cloud Sleuth properties and references to the underlying classes that consume them.

Property contributions can come from additional jar files on your classpath, so you should not consider this an exhaustive list. Also, you can define your own properties.

spring.zipkin.api-path		The API path to append to baseUrl (above) as suffix. This applies if you use other monitoring tools, such as New Relic. The trace API doesn’t need the API path, so you can set it to blank ("") in the configuration.
spring.zipkin.base-url	`http://localhost:9411/`	URL of the zipkin query server instance. You can also provide the service id of the Zipkin server if Zipkin’s registered in service discovery (e.g. zipkinserver/).
