April 2026

3 Commits • 3 Features

Apr 1, 2026

April 2026: Delivered three key features for the newrelic-java-agent, emphasizing observability, automated reporting, and token usage management. Implemented Reactor Netty HTTP client instrumentation with distributed tracing for Spring 6.x and reactor-netty 1.0.0+, enabling external call reporting and end-to-end traceability. Automated AIT performance metrics processing with wiki publishing to streamline stakeholder access to performance data. Added an LLM token counting utility with tests to improve accuracy of token usage tracking. No major bugs fixed this month; focus was on delivering high-value capabilities and strengthening integration points. Overall impact includes improved observability, faster stakeholder reporting, and more reliable token accounting across the agent. Technologies and domains touched include Reactor Netty, Spring 6.x, distributed tracing, AIT metrics automation, wiki publishing workflows, and LLM token management.
