Over a three-month period, this developer enhanced the alibaba/loongcollector repository by building and refining core system monitoring features. They implemented a CPU utilization metrics reporter in C++, refactoring the collector to compute detailed usage statistics using jiffies delta and adding unit tests for reliability. In the following month, they delivered a disk collector that monitors I/O statistics, file system usage, and disk serial IDs, improving data accuracy and resource management through careful use of Linux internals and file system management. Most recently, they introduced caching for disk file system information, optimizing performance and reducing redundant system calls in C++.

Sep 1, 2025September 2025: Implemented caching for Disk Collector File System Information in alibaba/loongcollector. Refactored GetFileSystemInformation to use a new SystemInterface cache, reducing redundant system calls and improving retrieval latency. This caching work lays groundwork for scalable, lower-latency disk data collection across deployments.

Jul 1, 2025For 2025-07, delivered a CPU Utilization Metrics Reporting feature in alibaba/loongcollector. The CPU collector was refactored to compute and report CPU utilization percentages (system, user, wait, idle, and other times) using jiffies delta. The change includes unit tests and a spelling fix in the cpuTotal variable. This work enhances observability, enables more accurate capacity planning, and reduces troubleshooting time by providing reliable CPU metrics. Committed as 5c804c9a4a209dbc3c7d26e463009bdbfeba4158 with message: feat: modify CPU collector (#2296).
