Add micrometer integration #1110

Open asarkar opened 6 years ago

As far as I can see, there is not a single mention of how to monitor the config server or what metrics are emitted out of the box. https://cloud.spring.io/spring-cloud-static/spring-cloud.html

The closest thing I could find is the Servo/Spectator section, but both are Netflix proprietary libraries. How can we configure config server to use Micrometer?

What type of metrics are you looking to collect?

What type of metrics are you looking to collect?

For starters:

Server: For each client:

  1. How many times it went to Git (or equivalent backend) and how long it took to fetch the data?
  2. Failure count/histogram for when item 1 fails.
  3. If there's a cache/sleep time (I asked for this feature long ago, not sure if implemented), then indicate that data is returned from cache and a trip to remote backend wasn't required. In other words, cache hit ratio.

Client:

  1. How many times it went to config server and how long it took to fetch the data?
  2. Failure count/histogram for when item 1 fails.
