问题
I am currently trying to migrate our prometheus lib to spring boot 2.0.3.RELEASE.
We use a custom path for prometheus and so far we use a work around to ensure this. As there is the possibility for a custom path for the info- and health-endpoint, uses management.endpoint.<health/info>.path.
I tried to specify management.endpoint.prometheus.path, but it was still just accessible under /actuator/prometheus.
How can I use a custom path or prometheus?
We enable prometheus using the following libs (snippet of our build.gradle)
compile "org.springframework.boot:spring-boot-starter-actuator:2.0.3.RELEASE"
compile "io.micrometer:micrometer-core:2.0.5"
compile "io.micrometer:micrometer-registry-prometheus:2.0.5"
we also use the import of the class PrometheusMetricsExportAutoConfiguration
Your help is highly appreciated :)

From the reference documentation:
By default, endpoints are exposed over HTTP under the /actuator path by using the ID of the endpoint. For example, the beans endpoint is exposed under /actuator/beans. If you want to map endpoints to a different path, you can use the management.endpoints.web.path-mapping property. Also, if you want change the base path, you can use management.endpoints.web.base-path.
The following example remaps /actuator/health to /healthcheck:
application.properties:
management.endpoints.web.base-path=/ management.endpoints.web.path-mapping.health=healthcheck
So, to remap the prometheus endpoint to a different path beneath /actuator you can use the following property:
management.endpoints.web.path-mapping.prometheus=whatever-you-want
The above will make the Prometheus endpoint available at /actuator/whatever-you-want
If you want the Prometheus endpoint to be available at the root, you'll have to move all the endpoints there and remap it:
management.endpoints.web.base-path=/
management.endpoints.web.path-mapping.prometheus=whatever-you-want
The above will make the Prometheus endpoint available at /whatever-you-want but with the side-effect of also moving any other enabled endpoints up to / rather than being beneath /actuator.
