I'm announcing an updated version 0.50 of the node status tool

with sinfo, so now we can do nice things with memory usage!
Hi! thank you for the great tool! i don't know if this is intended but :

while it is clear that the reported free mem is what is reported by free
as "free" one might argue that buffers/cache is memory available for
usage as it will shrink with the application usage ...
Maybe the FREE_MEM should be reported as (free + cached) ?
The pestat tool simply reports the free_mem value provided by sinfo.
I'm not sure I understand your point, but only SchedMD can change
Slurm's reporting.
