Overview

os.freemem() excludes page cache/buffers, so a healthy box with 8 GB and lots of cache shows e.g. "7.2 GB / 8 GB (90% used)" on the Workers tab and dashboard. Operators read this as memory pressure.

Suggested fix

Report MemAvailable from /proc/meminfo when present (fall back to freemem), and show disk usage for / alongside, which is the metric most people actually look for.
