Are there any official standards to help with monitoring service/microservice interactions?<p>I'm thinking as we have things like HATEOAS + HAL for design and representation of resources, shouldn't there also be something to help with tracking interactions?<p>A naive approach to this might be to just add a few standardized log entries into something like ElasticSearch.<p>I am not talking about monitoring in the sense of availability/SLA but rather a form of monitoring that tracks your service topology.<p>I found out about `zipkin` today, which seems to be somewhat in that direction, but my impression is that it is more of a product than a shared standard.<p>Thoughts?
