8CPU should correct.
Go debug mode and double check on what value it has. Your error message maybe due to:
1. U are not using snmp-5.4 and above for the system u going to monitor.
2. U didn't plot the individual CPU also.
3. Sometime, different system (cacti system) may end up having different value in the a, b, c, d and so on.

Hi all,
I'm trying to solve the same problem from days without results!
This is the debug (I have a dual socket quad-core board) :

I've installed net-snmp 5.4.1.2 from source (with the old net-snpm-5.3 got from apt-get install I have the same error) in the destination device to monitor.
Another strange behavior: when I create the graph for the host , cacti prompt me with three blank fields :
- Index Type
- Index Value
- Output Type ID
I need to monitor CPUs graph , this is the main reason I'm trying to use cacti. I'm using debian etch with cacti and net-snmp-5.4 compiled from source, I've rebuild the system three times to avoid procedures mistakes without results...help and thank in advance,
Simon

First of all, thanks for this really nice template. It works perfectly for me

I've had this problem too, but that was my solution:

Have you created the individual cpu graphs for the host?
If so you can probably skip this screen (i.e. enter nothing)... Then when the you go to "edit" the graph you can provide the individual data sources...

Thanks for the answer.
I try , but all data Source (Cpu0,Cpu1,etc...) has only one possible choice "Server XXX - CPU Utilization (cpu)" , I guess that must be one data source for every CPU (Cpu0,Cpu1....Cpu8) am I wrong?

I also had this problem.
But when you create/edit the device and add under: "Associated Data Queries" the data query: "SNMP - Get Processor Information" and create a normal Graph for it, you should have the needed data sources:
After this you can delete the normal CPU graph and create the one from the thread here. Then you should be able to choose the CPU0/CPU1/... data sources.

Thanks for the info.
In Associated data Queries I add "SNMP - Get Processor Information" with status "Success" [8 Items,8 Rows] that's Ok (I have a dual Xeon Quad motherboard).
When I make "Create Graph for this Host" I got Data Query [ SNMP - Get Processor Information ] with the processor index number from 0 to 7 . That's good I guessed.
I checked CPUs and create graphs but the problem is still there: it doesn't build graphs (data) . Now I have only the dead link of the graph.stop.
However I made a few steps !
EDIT:
In the console -> Collection Methods -> Data Queries -> SNMP - Get Processor Information -> Data input method I have selected "Get Script Server Data (Indexed)
Is that right?
EDIT 2:
In Graph Management In "Supplemental Graph TEmplate Data" -> Cpu Utilization Data Source I have "none" selected and I can't choose nothing like "cpu0" or "CPU1" or similarbut only the classic default data Sources.
This is the relative Debug :
RRDTool Command:
/usr/bin/rrdtool graph - \
--imgformat=PNG \
--start=-86400 \
--end=-300 \

So you mean, you can't do this?:
That means, that you don't have the data sources like this:
That means, you should add the normal CPU Graph again (That the data sources for each core will be added correctly)
I have to go now, I'll write tomorrow a step-by-step description, how I got it to work.

#FF0000FF <-- This looks like a color code (perhaps the one for the cpu graphic line), but it is wrong  there are too much letters (there are 8, ther have to be 6).
#FF0000 works and #0000FF works.

----------------------------------
Sorry - the CPU statistics (both original percentages, and the newer raw statistics) both refer to the system as a whole. There is currently no way to access individual statistics for a particular processor (except on Solaris systems - see below).
Note that although the Host Resources table includes a hrProcessorTable, the current implementation suffers from two major flaws. Firstly, it doesn't currently recognise the presence of multiple processors, and simply assumes that all systems have precisely one CPU. Secondly, it doesn't calculate the hrProcessorLoad value correctly, and either returns a dummy value (based on the load average) or nothing at all.
As of net-snmp version 5.1, the Solaris operating system delivers some information about multiple CPU's such as speed and type.
Other than that, to monitor a multi-processor system, you're currently out of luck. We hope to address this in a future release of the agent. |

Hello everybody,
after hours of heavy researchs I think that I can finally help !
As a linux user I couln't not have CPU infos because the templates "Generic SNMP-enabled Host", "Local Linux Machine", or "ucd/net SNMP Host" didn't give you access to Associated Data Queries "SNMP - Get Processor Information". I had sometimes "[0 Items, 0 Rows]" or the same problem as Edge and others.
The problem was that my LINUX CENTOS 5 server was running net-snmp v5.3. If you uninstall it and then install a beta version of net-snmp v5.5 (and net-snmp-devel), it's working. Beware, to get the Associated Data Queries "SNMP - Get Processor Information" working ("[2 Items, 2 Rows]"), I had to change my server's Host Template to "WINDOWS 2000/XP HOST" then save. This added this damn query
In fact I created my device with the logical "Local Linux Machine", then I choose "Generic SNMP-enabled Host", "ucd/net SNMP Host" and finally "WINDOWS 2000/XP HOST" to get : (save at each time)

Actually I can graph the two differents CPUs and I'll play with the templates from this thead to get both drawn in only one graph.
You can get newer versions of net-snmp here : http://net-snmp.sourceforge.net/wiki/index.php/Third-Party_Packages
You must of course have a valid configuration for snmp.conf, here is mine to allow easy access everywhere in my network :

So I couldn't get these graphs working, so I decided to create my own and share them with everyone else (And hopefully you can help me with my problem!)
So I created a script that using an SSH trust relationship will go to the target server and run mpstat.
Here's the script

From here I make a DIQ 'Script/Command' and referance these various Templates for 2/4/8/16 CPU servers. So, everything is working as I expect it but the first custom output is always 0. In the log files it comes back with a valid integer, however in the data source debug it shows "U" for the first value. ???
I'm stummped.
Here are the templates.

When I downloaded the multi.2.4.8.cpu.zip on page 9, it didn't work 'out of the box'.
I have imported the XML files in Cacti, this was going fine, but when I added the Graph Template called 'Host MIB - Multi CPU Utilization on 2 Processor Box' to my device:
Clicked Add and then clicked 'Create Graphs for this Host' and got this:
So in someway it was not working.
First off all, I want to thank the maker of these files and all the credits goes out to him, but I have changed some things.. for example:
In the graph there is a 'Mean CPU', I'm from the Netherlands and I didn't really know the meaning of 'mean' in this situation. I know I can be mean at someone but that shouldn't be right in this situation My dictionairy said that 'mean' is the same as 'average'.
But when we look in the graph and the statistics under the graph, we can see that 'Mean CPU' is not showing the average of the 2 CPU's:
So I have created a new CDEF which will add statistics of the 2 CPU's and then divide it in 2 so you got the average of the 2 CPU's.
I also changed the text 'Mean CPU' into 'Average', so people like me don't have to get their dictionairy  , and I changed the colour of the average graph a bit darker because it was a bit hard to see on my screen..
And I added the 'average' statistics under the graph in text format and I renamed the Template to 'CPU Utilization (2 CPU's)' because I want it to be on the top of the device page
The graph now looks like this:
You can download the 2 CPU version here, maybe I will make the 4 CPU later
Can someone give this one a try to see if it works?

But 2 CPU graphed OK.

Rael, I started setting up your mpstat scripts, and I'm getting output like this:
CPU1:1 CPU2:1 CPU3:6 CPU4:3 CPU5:12 CPU6:2 CPU7:5 CPU8:1
but my graphs are showing everything as NaN.
I notice in Data Input, that all the output fields are showing as "not in use":
Name Field Order Friendly Name Update RRA
CPU1 0 (Not In Use)
...
CPU8 0 (Not In Use)
and suspect that this is my issue. Can you, or anyone, point me to how to tweak this sufficient that it works?
