PROFILE
Adam Karpowich
Worked on the DataDog/datadog-agent repository, delivering features and fixes to enhance network monitoring, reliability, and observability in cloud environments. Developed and refined eBPF-based connection tracking, improved TLS traffic classification, and implemented granular telemetry for TCP failures using Go and C. Addressed data integrity by synchronizing TCP retransmission counts with kernel socket structures and introduced robust error handling for network ID retrieval. Enhanced system reliability through targeted bug fixes, regression testing, and cross-language data model alignment. The work focused on improving operational visibility, reducing mean time to repair, and ensuring accurate network metrics for enterprise deployments in production environments.

1 Commits
Nov 1, 2025Month: 2025-11 — Focused on reliability and data integrity in the DataDog agent. Delivered a targeted bug fix to TCP retransmission reporting that eliminates inconsistencies between retransmit counts and actual sent packets by aligning counts with the kernel TCP socket structure on connection closure. This improves accuracy of network metrics, dashboards, and alerts, and reduces false positives.

Dec 1, 2024Month: 2024-12 — DataDog/datadog-agent: Delivered Enhanced TLS Tagging for Network Performance Monitoring (NPM) to enable granular analysis of TLS parameters. The feature extracts negotiated TLS versions and cipher suites from handshake packets, enabling precise filtering and improved security visibility for network traffic. Work centered on a single commit implementing TLS tagging, setting the foundation for deeper NPM insights. Overall, this improves data fidelity for TLS-based traffic, accelerates root-cause analysis, and strengthens performance monitoring for enterprise deployments.
