It seems metricbeat system memory module is sending used memory value into free memory and free memory into used.
System.memory.total = 29320122368
system.memory.free = 280305664
system.memory. used = 29039816704
However, when I checked my linux machine, free memory is equivalent to used memory above and used memory is equivalent to free memory.
system.memory.free = 29039816704
system.memory. used = 280305664
Could someone guide me here as this is happening for all linux machines?
