BellSoft Unveils Hardened Java Images (2...

Quarkus 3.28 just shipped a feature Iโ€™ve wanted for years: Dashboards-as-Code.

You can now bundle Grafana dashboards directly in META-INF/grafana/ and Dev Services auto-provisions them on startup.
Metrics, dashboards, and even AI token tracking (LangChain4j + Ollama) โ€” all versioned with your source code.

A clean win for real #ObservabilityAsCode.

The goal of Arconia OpenTelemetry is to provide a single dependency you can add to your Spring Boot application to get unified Java observability with minimal configuration and maximum compatibility with both OpenTelemetry and Micrometer ecosystems.

Spring Boot Observability with Arconia OpenTelemetry

Arconia OpenTelemetry enhances observability for Spring Boot by combining the standardization of OpenTelemetry with the robustness of Micrometer.

How to Unit Test #Micrometer

How to Unit Test Micrometer | Baeldung

Unit testing metrics is crucial for ensuring that our application correctly tracks performance data and business metrics. By using Micrometer's SimpleMeterRegistry, we can create isolated tests that verify our metrics collection without requiring a full Spring context. When it comes to integration tests, we need to reset the MeterRegistry to perform assertions on it during our @SpringBootTests.

Researchers at the University of Gothenburg have made light-powered #gears on a #micrometer scale. This paves the way for the smallest on-chip motors in history, which can fit inside a strand of hair.

We have built a gear train in which a light-driven gear sets the entire chain in motion
