Excitement for Spring 1
The upcoming Spring 1 event in Las Vegas is highly anticipated, with excitement building among Spring fans and developers. This gathering is an opportunity for the community to come together, network, and share experiences related to Spring technology. For those unable to attend in person, a free live stream option is available for registration, allowing broader access to the event. The host expresses a strong eagerness to connect with attendees and facilitate engaging discussions during this important event.
Micrometer: An Observability Standard
Micrometer is recognized as the de facto standard for observability in Java applications, with its wide adoption since its incorporation into Spring Boot. Initially developed as a metrics library in 2017, it has since evolved to support various observability features beyond just metrics gathering. The project is deeply integrated within the Spring ecosystem but can also function independently of Spring frameworks, making it versatile for developers using other environments. Today, Micrometer is essential for numerous libraries and frameworks, enabling standardized measurement and observability practices across the Java landscape.
New Features and Enhancements
Recent updates in Micrometer include the introduction of the Observation API, which simplifies the process of instrumenting code for metrics, tracing, and logging without the need for repetitive code updates. This API allows developers to create observations with minimal boilerplate by defining handlers that automatically manage the associated metrics and tracing spans. Additionally, upcoming features look to enhance support for observability in distributed systems, such as adding exemplars to better connect metrics with traces. These improvements aim to streamline the process of monitoring application performance and facilitate deeper insights into system behavior.
Community Contribution and Collaboration
Micrometer thrives on a vibrant community of contributors who continuously enhance the project with new features and improvements. Notably, contributors like Johnny Lim have made significant contributions, illustrating the community-driven aspect of the project. The development process is facilitated through tools like Dependabot, ensuring that the project remains up-to-date with dependencies necessary for maintaining compatibility and performance. As new features are added, collaboration with other ecosystems, such as the transition from support for certain libraries, is managed carefully to minimize disruption for users.
Hi, Spring fans! In this installment we talk to observability legend Jonatan Ivanov about the latest and greatest in the wide and wonderful world of observability. (Turns out a library that's used by countless projects including and beyond the Spring ecosystem keeps quite busy!)
