In the previous chapter, we discussed how to carry out performance testing for a microservice-based application. Performance or load testing is a critical part of any application that serves a lot of users. A microservice-based application has a lot of small services that run on separate servers, and each microservice can be written in any language. For this reason, it is important that load testing is performed for each microservice.
This chapter will discuss performance monitoring of microservice-based architectures. We will look at various Application Performance Management (APM) tools that can be utilized to test microservices, and will also learn about performance counters that are specific to microservices.
After reading this chapter, you will be able to diagnose performance issues related to microservices and APIs using monitoring...
