metrics

There’s still an ongoing debate whether development in particular and IT, in general, are engineering practices. In all cases, there’s no denying that our industry is based on scientific foundations. Most of the organizations I’ve worked for implement the Deming wheel in one form or another: From a bird’s eye view, it makes a lot of sense. And given the success of the method in the Japanese car industry, there’s no denying that it’s effective. However,

Last week, I wrote about how one could migrate metrics from Spring Boot 1.5 to Spring Boot 2.0. This week, it’s time to check the different metrics available in Spring Boot 2.0 and how to create them. Meter There are 4 main types of metrics available: CounterGaugeTimerDistribution summary To keep the post readable in one piece, it will be limited to Counter and Gauge All metrics inherit from the base Meter class. A Meter provides basic measurement storage capabilities. As

I’ve already written about the excellent monitoring features available in Spring Boot. In Spring Boot 2.0, there has been a major rewrite regarding how the /metrics endpoint is designed. This is the subject of this post.

Some years ago, I discovered the Spring Boot actuator: Spring Boot includes a number of additional features to help you monitor and manage your application when it’s pushed to production. You can choose to manage and monitor your application using HTTP endpoints, with JMX or even by remote shell (SSH or Telnet). Auditing, health and metrics gathering can be automatically applied to your application. To sum it up, the actuator offers endpoints that allow monitoring of the application from

This week’s post aims to describe how to send JMX metrics taken from the JVM to an Elasticsearch instance. Business app requirements The business app(s) has some minor requirements. The easiest use-case is to start from a Spring Boot application. In order for metrics to be available, just add the Actuator dependency to it: <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency&
