Rorywelch

Rory Welch focused on stabilizing remote agent health checks for the instana/instana-agent-operator repository, addressing restart-induced downtime by refining the liveness probe mechanism. He replaced the container’s HTTP GET probe with an exec-based check that runs curl inside the container, enabling more accurate status assessments and preventing unnecessary restart loops. This targeted bug fix improved agent uptime and reduced false positives, resulting in more reliable telemetry and less operator intervention across deployments. Rory applied his expertise in Go, Kubernetes, and DevOps practices, demonstrating a thoughtful approach to in-container diagnostics, probe strategy design, and regression awareness within a production environment.
