在spring boot中导出指标

Question

spring boot shows all the possible metrics in /metrics endpoint. on the other hand, internally it uses metrics exporters. for example when you add dropwizard metrics (current de facto standard?) it gets registered automatically but not all spring-boot metrics are exported to dropwizard. in order to have more/all metrics, one has to manually register different metric sets. and it has to be maintained in parallel to what spring-boot does for /metrics endpoint.

so the question is: how it should be done properly? should i use metrics exporters and maintain it for each of dozens microservices or use Collection<PublicMetrics> used by /metrics endpoint and maintained by spring?

Answer 1

Use only dropwizard metrics to instrument your code since it has a more intuitive API then the Spring.

With the spring-dropwizard ( http://metrics.ryantenney.com/ ) integration, all dropwizard metrics are getting exposed to the endpoint /metrics, so you do not need to register anything manually.
