Monitoring microservices

Microservices are truly distributed systems with fluid deployment topology. Without a sophisticated monitoring in place, the operations team may run into trouble managing large-scale microservices. Traditional monolithic application deployments are limited to a number of known services, instances, machines, and so on. This is easier to manage as compared to a large number of microservices instances potentially running across different machines. To add more complications, these services dynamically change its topologies. The centralized logging capability only addresses part of the issue. It is important for the operations team to understand the runtime deployment topology, and also the behavior of the systems. This demands more than centralized logging can offer.

In general, application monitoring is more of a collection of metrics and aggregation and validating them against certain baseline values. If there is a service-level breach, then monitoring tools generate...
