- Implement cgroupmon monitor with 17 metrics across CPU, memory, I/O, and process counts - Support automatic detection of cgroup v1, v2, and hybrid environments - Parse cgroup controllers: cpu.stat, memory.stat, io.stat for both versions - Integrate with prmon build system and test infrastructure - Add Python and GTest test harnesses with precooked cgroup v2 fixtures - Update documentation: README, ADDING_MONITORS, CONTRIBUTING with usage and Windows dev notes - Enable container resource tracking with --disable cgroupmon flag - Provide more accurate I/O statistics for containerized workloads
…ead counting - Remove unused cgroup_stat_update variable in update_stats() - Fix read_single_value() to count lines for cgroup.procs and cgroup.threads instead of reading first value, since these are multi-line PID lists
