%memused is somewhat useless, as Linux claims most unused memory for caching, even it is not in use.
it is will known that much of the buffer space can be treated as free memory
%memused always includes the cache memory, and frequently hovers around 90%, even though real usage is much lower.
perform this calculation in this tool set and set %memused to the real value
# Formula for true memory utilization
total_mem = df['kbmemfree'] + df['kbmemused']
real_free_mem = df['kbmemfree'] + df['kbbuffers'] + df['kbcached']
real_used_mem = total_mem - real_free_mem`
