KiB Mem : 16260192 total, 195472 free, 15297300 used
KiB Swap: 16257532 total, 8238932 free, 18600 used. 8257532 cache
- My actual memory usage is
15297300 / 16260192 = 0.94
, right? but the value that metricbeat collects is(16260192 - 8257532) / 16260192 = 0.49
.
I guess it's supposed to subtract buffer/cache of memory, but it's actually subtracting the cache of swap.
