June 2025 monthly summary for wazuh/wazuh focused on reliability, test coverage, and CI/CD alignment to deliver business value with more stable deployments and artifact integrity. Key features delivered: - Cluster Restart Core Improvements: Excluded master node from distributed restarts, centralized restart execution via the DistributedAPI, and strengthened error handling for restart operations. Commit trajectory includes adding master node conditions, using DAPI for local master requests, validating non-empty responses, and preventing wrapper exceptions due to missing permissions. - CI/CD AWS S3 Bucket URL Migration: Migrated CI/CD artifact storage to the new S3 bucket to consolidate builds and ensure artifacts are stored in the correct location. Multiple commits updated the package bucket URLs consistently across the repo. Major bugs fixed: - Cluster Restart Tests and Validation: Improved restart-related unit and integration tests to validate correct node targeting, local master restart behavior, and accurate reporting of affected items, with accommodations for asynchronous operations. - Agent Health Check Reliability: Strengthened health check evaluations to reduce false negatives and improve reliability of health status reporting across configurations. - RBAC Testing Improvements: Enhanced integration tests to better validate permission-denied paths and expected API responses in RBAC scenarios. - Agent Group Counts Integration Test Fix: Corrected integration test expectations for agent group counts to reflect intended state and improve test accuracy. Overall impact and accomplishments: - Increased cluster restart reliability and observability, enabling safer upgrades and fewer on-call incidents. - More deterministic health status reporting and improved test coverage across restart, RBAC, and agent-related functionality. - Consistent artifact storage in CI/CD, reducing build failures due to misrouted artifacts. - Strengthened release quality through expanded integration tests and better validation of asynchronous workflows. Technologies/skills demonstrated: - Distributed API (DAPI) orchestration and master-local request handling. - Robust unit/integration test development and maintenance. - Health-check design and reliability hardening. - CI/CD pipeline maintenance and cloud storage migrations (AWS S3). - Test data accuracy and RBAC API validation.

May 2025 highlights for wazuh/wazuh: Delivered a unified Wazuh DB HTTP client and a comprehensive synchronization overhaul, added a Consolidated Agent Summary API, and refined API restart workflows. Key outcomes include robust HTTP-based agent operations with wazuh-db, migration to the new WDB HTTP client, removal of brittle internal parsing in favor of dictionary-based models, and enhanced test coverage. These changes reduce coupling, increase reliability, and improve scalability for agent management.

April 2025 monthly summary for wazuh/wazuh: Focused on performance, reliability, and maintainability improvements across agent data retrieval, RBAC, and CI/CD processes. Key features delivered included agent data retrieval and group expansion improvements, reorganization of RBAC utilities with TTL caching, and CI/CD workflow simplifications. Collectively these changes reduced data access latency, improved governance checks, and streamlined the development lifecycle, enabling faster iteration and safer scale. Key outcomes include faster and more reliable agent data access, lower RBAC overhead through caching, and standardized, documentation-aligned CI that reduces build times and drift across environments.

March 2025: Delivered two major capabilities in wazuh/wazuh that advance performance, reliability, and observability. Implemented authentication and database pool performance enhancements to boost concurrency and throughput, and significantly improved the Distributed API instrumentation, test coverage, and CI hygiene.

February 2025 monthly summary focusing on key accomplishments and business value for wazuh/wazuh. Delivered a critical bug fix to normalize OSSEC log timestamps to UTC, improving reliability of centralized log analysis and cross-host correlation.

Month 2025-01: Focused on delivering measurable improvements to CI testing visibility and reporting for wazuh/wazuh. Delivered CI Test Report Generation feature, enabling generation of test reports across CI workflows, and integrated a QA integration framework to parse and surface test outcomes, driving faster analysis and problem detection. Maintained core stability with CI/CD best practices and ensured traceability to the committed changes.
