Searching through the archives I see this has been talked about, but I have read a few examples that have confused me.
Here is what I get from it please let me know if this is the correct understanding :)
Absolute=
This is for things that I'm interested in knowing what the value is currently.
For example - I want to know when my memory is 80% utilized, and I will check for it every 2 minutes.
And Absolute can also be used to monitor something like, I want to know when I have processed 1,000,000 incoming packets. Something that has been counting up since my last reload.
Delta=
This is when I want to look at averages/rate of change.
For example- This would be if I wanted to know in the last 5 minutes have I used 40% more of my memory.
This could be useful in this situation- I have a virus that is creating thousands more NAT translations in just moments, and my memory went from 40% to 95% in 5 minutes.
Is this right?
Thanks,
J Wireman
