We have created our application with Spring-Cloud Eureka and Spring-Cloud Zuul with multiple core / support micro services registering to Eureka and accessed via Zuul, everything works fine.
We wanted to collect metrics of the APIs that is accessed via ZUUL. For example, API - ".../extract" need to know how many times its accessed in 5,15 and 60min time period.
We did some analysis and found various metrics library like Netflix Servo, Dropwiard Metrics, Spring Boot Actuator. Everything points to implementation at the service or API level. We wanted our metrics to be captured at ZUUL itself so that a simple counter is implemented in ZUUL and that would provide us the required metrics. Any suggestion in how to implement this would be helpful.
