I mean it doesn't work in giving me the actual Load value.
The expression you mentioned will give be perfect in defining the threshold
but the value that this expression will give will be (Actual Load Value -
Number of CPU Cores).
How do I still get the actual Load value to print in the alert with
threshold still being the Number of Cores.
