Jun 1, 2025June 2025: Delivered Volcengine alert integration for Hertzbeat, adding DTOs for event and metric alerts and a parsing service to convert Volcengine alerts into a unified SingleAlert format. Implemented webhook reception and configuration flows, plus user-facing documentation to enable quick onboarding. This expands alert coverage and strengthens unified alert management for Volcengine-originated alerts.

Mar 1, 2025March 2025 monthly summary for apache/hertzbeat: Delivered security-focused enhancement to the plugin upload workflow by introducing server-side validation for plugin filenames (validateFileName). This change prevents null names, directory traversal, and newline characters, strengthening the robustness of the plugin ecosystem. No additional major bugs fixed this month; focus was on hardening and reliability of the upload process.

Dec 1, 2024December 2024 monthly performance summary for apache/hertzbeat: Delivered two major observability enhancements that improve data fidelity and troubleshooting capabilities. HTTP Response Header Monitoring: introduced parsing type 'header' to extract HTTP response header values using aliases; updated app-api.yml and app-clickhouse.yml to enable detailed HTTP response analysis. This work increased the granularity and accuracy of header-based metrics and improved correlation with downstream services. Associated commit: d4f6fc1ae8988ca95ce535bcbcd1666febd68203, which included a fix for the ClickHouse monitor to ensure reliable data ingestion. Enhanced Linux Process Monitoring Metrics: added new VM and I/O metrics from /proc (VmPeak, VmSize, rchar, wchar, etc.); updated configurations to include these metrics and adjusted the data collection script to support richer process-level visibility. Associated commit: a27777adcbc269c24a84b8c0450480e54afa12a6 (improve linux process). Overall impact: stronger observability, faster root-cause analysis, and better capacity planning through richer HTTP and Linux process telemetry. Technologies demonstrated: YAML configuration management (app-api.yml, app-clickhouse.yml), header parsing logic with aliasing, /proc-based metric collection, and data collection scripting; demonstrated collaboration and code quality improvements.
