Understanding Spring Boot Actuator metrics
In the previous recipe, we learned how to configure Spring Boot Actuator in the geolocation application. We also verified the configuration by accessing the /metrics endpoint. In this recipe, we will be learning more about most of the commonly used metrics exposed by Spring Boot Actuator.
Getting ready
In order to understand the various metrics and operations exposed by the Spring Boot Actuator library, we will be invoking them one by one using cURL commands. As we will be analyzing the JSON response of our metric APIs a lot, feel free to use a tool such as Postman or another plugin for your browser to pretty-print JSON documents.
How to do it...
The next few steps in this recipe will help you go over the most important endpoints exposed by Spring Boot Actuator.
Some metrics exposed by Actuator depend on the API usage, so let's create some geolocations and try to query them:
curl -H "Content-Type: application/json" -X POST -d '{"timestamp": 1468203975...
