April 2026: Delivered end-to-end eBPF-based log collection with trace correlation in the odigos project, enabling automatic correlation of application logs with traces and metrics. Introduced configurable receivers to toggle between eBPF and filelog log collection, and extended instrumentation rules to support dynamic process registration for eBPF log capture. Implemented the end-to-end ebpf log capture flow (log_event deserialization, TGID-keyed per-process attribute mapping, and trace context propagation) and wired it into the existing collector pipeline. Added the ebpf-log-capture instrumentation rule to control receiver selection and ensured runtime config updates propagate without additional RBAC. Released a ready-to-use profile manifest at profiles/manifests/ebpf-log-capture.yaml. These changes deliver faster root-cause analysis, improved observability, and a unified telemetry surface across logs, traces, and metrics.

February 2026 monthly summary for BenElferink/odigos. Focused on enhancing observability and monitoring readiness by delivering advanced JVM metrics collection, improved temporality handling, and stronger integration with popular monitoring tools (New Relic and Grafana). This work reduces client-side metric calculations, aligns with standard dashboards, and enables faster issue detection and data-driven decisions.

Month: 2026-01 | Repository: odigos-io/odigos Concise monthly summary: Focused on advancing JVM metrics collection architecture by introducing a dual-map design and a dedicated AttributesMap. Replaced the 512-byte packed key with a 64-byte UUID to enable scalable data handling, and unified map FD transfer over a single Unix socket using the ConnectAndListenMulti client and sendFDs server. This work aligns with the ebpf-java-instrumentation dependency and sets the stage for easier metrics enrichment and performance improvements in downstream consumers.

June 2025 — Key focus on instrumentation and telemetry improvements in AvihuHenya/odigos. Delivered PGX Instrumentation: Telemetry Attributes for Category and Transaction Type, enabling better categorization and processing of database telemetry when the pgx package is detected. No major bugs fixed this month. Business impact: improved observability, faster root-cause analysis, and more actionable telemetry dashboards. Technologies and skills demonstrated: Go instrumentation, pgx integration, telemetry attributes design, and careful, backward-compatible changes.

December 2024 monthly summary for kubearmor/KubeArmor: Implemented containerd v2 migration with event-driven runtime integration, enabling real-time task event monitoring and more accurate policy enforcement. Added AppArmor hardening by enabling D-Bus support in host and privileged profiles. Implemented AppArmor host cleanup on graceful termination to prevent lingering profiles and improve uninstall reliability. Overall, these efforts improved runtime correctness, security posture, and maintainability, delivering business value through stronger security controls and robust lifecycle management. Technologies/skills demonstrated include containerd v2 APIs, event-driven architectures, AppArmor profiles, D-Bus integration, and lifecycle cleanup.

November 2024: Focused on hardening AppArmor integration in kubearmor/KubeArmor by addressing template sanitization to improve cross-version compatibility and stability of policy generation.

Concise monthly summary for 2024-10 focusing on security hardening, procfs handling, and AppArmor policy robustness for kubearmor/KubeArmor. Implemented host isolation improvements, enhanced testability, and strengthened policy generation to reduce conflicts and improve maintainability.

2024-08 monthly summary for kubearmor/KubeArmor: Delivered a targeted performance enhancement for event processing by streamlining handling of process and mount namespaces in event data structures. Implemented namespace-aware optimizations in the BPF/enforcer path and event maps, improving processing efficiency and scalability. The change reduces CPU overhead in high-throughput environments and strengthens the reliability of enforcement decisions across clusters.

April 2024 monthly summary for kubearmor/KubeArmor: Delivered a targeted enhancement to BPFLSM enforcement, improving source buffer checks and execution name matching to strengthen security posture. Implemented a build command modification to disable stack protection in specific scenarios to evaluate potential performance gains. Engaged in dogfooding of the changes (commit 0ebe696720c53728a079e8aaea3dd0cce362be45). While no major bugs were documented this month, the work lays the groundwork for more robust policy enforcement and performance-optimized deployments. Technologies demonstrated include kernel-level security enforcement (BPF/LSM), build system customization, and real-world validation workflows.

February 2024 monthly summary for kubearmor/KubeArmor: Focused on strengthening container security through policy presets and protection for environment variables. Implemented Container Security Presets and Environment Variable Protection by introducing new presets, BPF-based enforcement for file access in containers, and updated monitoring to support policy presets and events. This work aligns with the security hardening roadmap and enables safer container deployments with granular policy control and protected environment variables.

January 2024 monthly summary for kubearmor/KubeArmor focusing on access policy hardening. Key delivery: fix for owner-only and readonly access policy enforcement, ensuring correct permission enforcement based on user ownership and read-only flags. This fix reduces security risk from misconfigured policies and improves compliance with security policies across deployments. Implemented in commit bf6d287090ef13f252de5c82d648ddda946b7c9a. Overall impact: increased security, reliability, and auditability of access controls. Technologies/skills demonstrated: Go-based policy engine, access control logic, patch review and validation, and security-centric testing.
