GitHub user edespino added a comment to the discussion: Introducing the [perfmon] Extension for Cloudberry Database Monitoring
@fanfuxiaoran Thanks for confirming that `libsigar` is still in use. However, I’d strongly encourage us to reconsider that position. Continuing to depend on `libsigar` **without any plan to replace or modernize it** introduces significant risks to the Cloudberry project: ### ❌ Why `libsigar` is problematic: * **Unmaintained**: No upstream development or security patches in years. * **Broken on modern platforms**: Build issues are common on RHEL 9, Debian 12, Alpine, macOS, etc. * **Difficult to patch**: Contributors will be forced to debug outdated C code and platform-specific breakage. * **Portability blocker**: This limits adoption on modern developer workstations, CI systems, and containers. * **ASF sustainability concern**: Bringing in obsolete dependencies violates the spirit of maintainability and long-term openness expected in ASF projects. ### ✅ What we need: If `perfmon` is to become a core part of Cloudberry’s monitoring infrastructure, we should at minimum: * **Track this as a known technical debt item**, with a defined migration path or plan to deprecate `libsigar` * **Abstract `libsigar` usage** behind an interface, so it can be replaced in a modular way * **Evaluate modern replacements**: * `/proc`-based stat readers (Linux-only, but simple) * Integration with system libraries like `libstatgrab`, `psutil`, or systemd APIs * Shell out to `vmstat`, `iostat`, or `/sys/fs/cgroup` metrics as a fallback Without a plan, we risk adopting legacy constraints that will slow down contributors and users alike.
