So many check_mem scripts out there but I am still not satified so I wrote my own.
Many scripts report the total use of memory but they dont care how much memory is placed in cache by the OS or an Application.
Well using vmstat or free we can get just that.
the syntax is simple
The graphs work as well, I calculated the % used of either swap or RAM memory.
I know it can be improved but its working good enough for me.
A great reference about how swap memory works
Great graphs on memory by Dr. Carter
I want to get my plugin to graph exactly like that one, any help is welcome.
