How does LuCI calculate the "total available" and "used" values? I am finding that they differ from the output of some CLI tools on my x86/64 box:
# free -h total used free shared buff/cache available Mem: 15Gi 1.2Gi 9.9Gi 455Mi 4.0Gi 13Gi Swap: 0B 0B 0B
I guess it is the sum of used and buff/cache?
Which is inconsistent with htop:
# htop Mem[|||||||||||||| 1.19G/15.1G]
