Graph the average utilisation of 4 cpus on a server

Hey guys.

I have those server where I have more than 1 cpu, for exemple, one server have 4, and I would like to consolidate all the data in a nice graph with juste one line.

Once this is done, I would like to be able to add another server to that same graph, so instead of have 8 lines for 8 cpus, I'll have 2 lines for an average of 4 cpu/server each.

Is it possible, and how?
Thanks.

Something like: http://monitor.idleserv.net/traffic.html ?

The bottom 4 graphs have been added together creating a total in the top graph.

Kinda like that, but you added the 4 graphs together..

What I want on my side is an average of all 4 graph.. if I had all my cpu utilisation % it will give me an unreal % over 100%

I really need an average.. or a SUM / 4

I checked you other graphs, is GS1 a computer or a router or what? the data you get from it is very interesting..

Yea its possible to do an average for them

might write u the templates if i have time.

GS1 is a game server for Counter Strike - 32 players

these graphs are very interesting, is it a windows or linux server? i wonder how you can get the memory and load average.. and that cpu graph, you have a way to separate system and users...

I guess because i query windows servers, i cant do that...

There all Linux servers except for Shuttle, that is Windows XP.

Well, i'm still looking for an answer to my problem (the average), if anyone can come up with sumthing..

I would suggest learning RPN.

Add all the data sources to the graph, but do not graph them. Then create a CDEF equation to add up then average the results from the 4 CPUs. Add a graph item to graph the results of the CDEF equation.

It's long, but it works. Read the documentation, and look at the example CDEF equations.

Adding 4 sources together would be,

d,c,a,b,+,+,+

or you could simply use the special directive when creating a CDEF to use "all data sources no duplicates".... and divide by 4...
