Monthly Summary – 2025-10 This month, performance-focused deliverables across two NR Kubernetes projects improved stability, reliability, and observability in Kubernetes workloads. Key changes: - newrelic/k8s-agents-operator: Fixed unintended pod mutations on UPDATE events by removing pod mutation during UPDATE and ensuring webhook mutates only on CREATE. This reduces risk of unintended pod changes and stabilizes upgrades and rolling updates. Commit 0514775ffab72a3d7dbabe3c975c5a597aa890d8 (fix: remove pod mutate on update (#410)). - newrelic/nri-kubernetes: Addressed scraper timing stability by ensuring scrape intervals respect configured timing; added high-latency logging and detailed duration metrics for scrape, publish, and total time. Introduced a measureTime utility to time code blocks for accurate performance accounting. Commit e70adbbcfef51740f25628a7b2601f7f76c22d1f (fix: add messages for high latency during scrape and publish (#1215)). Impact: Reduced mutation-related pod risks; improved data freshness reliability and observability. Better diagnostics and capacity planning through enhanced metrics and logs across the two core NR Kubernetes projects. Technologies/skills demonstrated: Kubernetes admission webhooks (mutation on CREATE only), Go-based service/workload modifications, observability instrumentation (logging, metrics for scrape/publish/total durations), performance timing utilities (measureTime), and incident mitigation through proactive instrumentation.

Month: 2025-08 — Delivered impactful instrumentation enhancements for newrelic/k8s-agents-operator, including extended Kubernetes container name handling, Java instrumentation extensions support, and Go tooling/testing updates. These changes improve reliability, cross-language integration, and developer experience through CI improvements and test coverage, enabling safer deployments and faster iteration.

July 2025: Delivered Kubernetes Agent Instrumentation API v1beta2 in the newrelic/k8s-agents-operator, with API refactor, webhook enhancements, and CI workflow updates to enable automatic instrumentation of containerized workloads in Kubernetes. No major bugs fixed this period; improvements focused on automation, reliability, and upgradeability, delivering measurable business value through faster instrumentation rollouts and enhanced telemetry.

Concise monthly summary for 2025-05 focusing on the New Relic Kubernetes agents operator: - Delivered container-targeted instrumentation to enable precise per-container telemetry within pods. This reduces overhead and improves signal quality by targeting specific containers for instrumentation. - Refactored instrumentation pipeline for better code organization, enabling easier maintenance and future container-level features. - Expanded test coverage around the container-targeting feature to increase reliability and reduce regression risk. - Demonstrated practical impact through a focused commit implementing the feature (fab6eaf118e28fd3652d51c8d36a519075944bc1) in the newrelic/k8s-agents-operator repo. - Repository context: newrelic/k8s-agents-operator.

April 2025 monthly summary for the newrelic/k8s-agents-operator. Focused on stability, deployment flexibility, and security through unified environment variable injection, host-network support for metrics/health probes, and dependencies/tooling upgrades. Delivered features include unified env var injection across PHP and other language agents (PHP_INI_SCAN_DIR handling), host network support with configurable bind addresses for metrics/health probes, and up-to-date dependencies and tooling to improve build stability and security patches. Impact: smoother deployments, more reliable instrumentation, improved security posture, and easier ops with updated Helm configurations. Technologies exercised include Go, Kubernetes operator patterns, Helm, and CI/lint/dependency management.

March 2025 monthly summary focusing on developer contributions across two repositories (newrelic/nri-kubernetes and newrelic/k8s-agents-operator).

February 2025 (2025-02) monthly summary for the repository newrelic/k8s-agents-operator: Delivered PHP 8.4 support for the K8s Agents Operator. This work updates the instrumentation webhook to include PHP 8.4 in supported languages, upgrades the PHP deployment image to 8.4, and adds a test case to validate version retrieval. The change broadens runtime compatibility for PHP workloads on Kubernetes, reduces upgrade risk for customers migrating to PHP 8.4, and supports our strategy to extend language coverage with minimal operator disruption. Key technical achievements and learnings include webhook enhancement, image versioning, and test automation, all performed with an emphasis on stability, backward compatibility, and measurable business value.

January 2025 monthly summary for newrelic/k8s-agents-operator: Key health-monitoring feature delivered for the operator, including a dedicated health-check sidecar, reconciliation-loop integration, and pod-health-based status updates for instrumentations. Instrumentation conversion robustness improved with comprehensive unit tests (ConvertTo/ConvertFrom) and a refactor of application setup into helper functions, enhancing maintainability. Minor regression fix applied to health agent environment and container configuration to ensure correct runtime behavior. Overall impact: increased operator reliability, improved observability, and stronger maintainability, enabling faster response to health-related incidents. Technologies/skills demonstrated: Kubernetes operator patterns (controller-runtime), Go, webhook configurations, Makefile tooling, unit testing, and agent injector adjustments.

Month 2024-11 monthly summary for newrelic/k8s-agents-operator focusing on business value, reliability, and expanding PHP coverage in Kubernetes. Delivered targeted fixes to improve test stability, environment propagation, and end-to-end validation, strengthening production readiness and developer velocity.
