+=== Can you please elaborate the difference between oomguarpages and privvmpages? ===
-Both seem to be showing mem + swap. Is the difference between two about allocated but not used pages? I mean, privvmpages show allocated (some of which might not be used) for mem + swap, whereas oomguarpages show allocated, all of which are used, mem + swap? ====
 ==== Answer: ====
 Yes, oomguarpages current value shows actual usage of MEM+SWAP.
