How do you calculate the RAM on windows (perfmon) ?

[henriq_c]

Hello,

I want to calculate the percentage of the RAM utilization and I do this but I know it is not good. Do you have a better proposition ?

index=xxx host=xxxx eventtype="perfmon_windows" object="Memory" counter="% Committed Bytes In Use"
| timechart span=1m eval(round(latest(Value),4)) as "RAM"

Same for the RAM utilization in Go :

index=xxx host=xxxx eventtype="perfmon_windows" object="Memory" counter="% Committed Bytes In Use" OR counter="Committed Bytes"

| eval percentused = case( counter=="% Committed Bytes In Use", round(Value, 4) )
| eval committed = case( counter=="Committed Bytes", round(Value, 4) )
| eval usedbytes = (percentused/100)*committed

| timechart span=1m eval((round(latest(percentused),4)) / 100 * round(latest(committed),4) / 1000000000) as "RAM"

Thanks
