Linux-specific readers for /sys and /proc.
These cover what sysinfo does not expose: hwmon sensors, RAPL energy
counters, per-device disk I/O, btrfs and mdadm state.
Every reader takes its root directories from SysRoots instead of
hard-coding /sys and /proc, so tests can point them at a fixture tree.
Modules§
- btrfs
- btrfs filesystem health from
/sys/fs/btrfs/<fsid>. - diskstats
- Per-device disk I/O from
/proc/diskstats. - hwmon
- Hardware monitoring chips from
/sys/class/hwmon. - mdstat
- Linux md (mdadm) arrays from
/proc/mdstat. - meminfo
- Supplementary memory figures from
/proc/meminfo. - mounts
- Mount table from
/proc/mounts. - net
- Network link state from
/sys/class/net/<iface>and, for Wi-Fi,iw. - rapl
- CPU package power from RAPL energy counters in
/sys/class/powercap.
Structs§
- SysRoots
- Root directories of the kernel pseudo filesystems.
