Performance Metrics (APM) for Spring Boot Microservices on OpenShift

Performance Metrics (APM) for Spring Boot Microservices on OpenShift

OpenShift provides a built-in monitoring tool called Hawkular. That tool is in charge of collecting metrics from Docker containers through the Kubernetes interface and storing, aggregating, and visualizing them. The metrics collected are CPU, Memory, Disk, and Network usage. Hawkular offers a “black-box” view of container performance but does not deal with application metrics like service performance or distribution of response time through application layers. For this specific case, the Hawkular community is working on another module called Hawkular APM that provides insight into the way an application executes across multiple (micro) services in a distributed (e.g. cloud) environment.

What is Enterprise-Ready Kubernetes?

What is Enterprise-Ready Kubernetes?

Over two years ago, the OpenShift team made a critical decision to support both Docker containers and the emerging Kubernetes project. At the time, that decision was a classic innovator’s dilemma. Their challenge at the time was not unlike the conversations that we have with customers on a daily basis. How can their company make a transition towards becoming a more digital-native company? How can their company get there without abandoning all of their existing investments, or giving up some existing advantages they have in their marketplace? How can they avoid building a DIY platform?
