}

Memory snapshot from /proc/meminfo. All values are in mebibytes (MiB = 1_048_576 bytes), standardized to match Python resource-tracker PR #9 which also adopted MiB throughout.

Fields

total_mib: u64

free_mib: u64

Truly free RAM (MemFree from /proc/meminfo). Matches Python memory_free.

available_mib: u64

Free + reclaimable RAM (MemAvailable from /proc/meminfo). Superset field.

used_mib: u64

Used RAM excluding buffers/cache (MemTotal - MemFree - Buffers - Cached). Matches Python memory_used.

used_pct: f64

Fraction of total RAM in use (0.0–100.0).

buffers_mib: u64

Memory used by kernel I/O buffers (MiB).

cached_mib: u64

Memory used by the page cache including slab-reclaimable (Cached + SReclaimable). Matches Python memory_cached.

swap_total_mib: u64

swap_used_mib: u64

swap_used_pct: f64

Fraction of swap in use (0.0–100.0). 0.0 when no swap is configured.

active_mib: u64

Memory used by active pages (MiB). Matches Python’s memory_active.

inactive_mib: u64

Memory used by inactive pages (MiB). Matches Python’s memory_inactive.
