PROFILE

Greg Agacinski

Greg contributed to several Nobl9 repositories, focusing on backend and infrastructure improvements using Go, Terraform, and HCL. He enhanced the terraform-provider-nobl9 by automating historical data replay during SLO creation, adding robust error handling and user messaging to improve reliability and transparency. In nobl9-go, Greg delivered configurable Prometheus data resolution and implemented account group filtering for ThousandEyes metrics, enabling more granular and multi-tenant observability. His work included configuration-driven feature design, validation logic, and comprehensive unit testing. Across these projects, Greg addressed edge-case bugs and maintained backward compatibility, demonstrating depth in API integration, backend development, and infrastructure as code.

Month: 2026-03 — Nobl9-Go: Delivered AccountGroupID-based account group filtering for ThousandEyesMetric, enabling filtering of test results by account group context. Implemented an optional AccountGroupID field (AccountGroupID *int64) with non-negative validation, updated example YAML, and added unit tests covering both valid and invalid values. Commit reference: 672ba6b93dccedd3b56700007ad1a738d1991e1d. Co-authored by Nikodem Rafalski. Impact: enables precise multi-tenant data slicing for ThousandEyes tests, improving data isolation, reporting accuracy, and troubleshooting efficiency. No critical bugs reported; quality improvements include validation and test coverage across the feature. Key deliverables: - Added AccountGroupID with validation to ThousandEyesMetric - YAML examples updated to demonstrate new field - Unit tests for valid and invalid AccountGroupID values - Release notes and cross-repo alignment (PC-18683 / PR #876) - Business value: sharper dashboards, more accurate SLOs, and streamlined cross-tenant data access.

September 2025 monthly summary for nobl9-go focused on delivering configurable Prometheus-based data resolution. Implemented an optional 'step' parameter for Prometheus integrations (Agent and Direct) to configure data resolution in seconds, with a minimum of 15 seconds. This enables non-default granularity for metrics, improving observability and alerting fidelity while maintaining backward compatibility. Key accomplishments: - Feature delivered: Prometheus data resolution step configurability (PC-17681). Commit: 1ca2a99aa18bbe18865f41835a49813451cf0279. PR notes reference #796. Major bugs fixed: - None reported/fixed in this scope. Overall impact and business value: - Enhanced metric fidelity and dashboard accuracy by allowing finer data granularity in Prometheus-based integrations, leading to better operational visibility and faster detection of anomalies. - Establishes a foundation for future observability enhancements in the nobl9-go repository. Technologies/skills demonstrated: - Go programming, Prometheus integration patterns, configuration-driven feature design, backward-compatible API changes, and disciplined commit messaging (PC-17681).

December 2024 focused on stabilizing replay queue timing in nobl9/sloctl by addressing a critical offset handling bug. The fix ensures that the offset is not applied to the From timestamp when playlists are available and only applies when playlists are not available, reducing mis-timed replays and aligning behavior with playlist-driven workflows. This work enhances reliability for replay scheduling and improves user experience where playlists govern timing.
