PROFILE

Marek Šimek

Worked on SolarWinds OpenTelemetry Collector projects, focusing on telemetry export reliability, security, and deployment readiness. Addressed OTLP port misconfigurations in both solarwinds-otel-collector-releases and solarwinds-otel-collector-contrib, ensuring telemetry data reached the correct endpoints and improving observability accuracy. Enhanced security by implementing end-to-end TLS testing with self-signed certificates and enabled Kubernetes-specific distributions through Dockerfile and Makefile updates. Improved data attribution by appending collector names to exported signals and maintained license compliance by updating headers and dependencies. Utilized Go, Docker, and Shell scripting to automate builds, manage configurations, and enforce CI/CD standards, resulting in more robust, secure, and maintainable observability infrastructure.

Month: 2024-12 — Telemetry export reliability improvements across SolarWinds OpenTelemetry Collector projects. Delivered critical OTLP port configuration fixes to ensure telemetry is exported to the correct endpoint, updated configurations, and refreshed tests and documentation. In solarwinds-otel-collector-releases, the OTLP port was updated from 4317 to 443 across data centers to ensure telemetry exports reach the correct endpoint; in solarwinds-otel-collector-contrib, the default OTLP port in the SolarWinds exporter was corrected to 443 with accompanying config and unit test updates. Both efforts included CHANGELOG updates. These fixes reduce data routing errors, improve observability backend accuracy, and strengthen customer-facing telemetry SLAs.
