Multi CPU Utilization Graph

[argon0]

First thing we need to know is the version of Cacti you are using.

It looks like a cdef problem...

The way CDEFs work changed (temporarily) with version .87c (IIRC).

i have cacti 0.8.7b (today i install from my debian 2.6.26-2-amd64 - aptitude install cacti)

i see on CDEF options values - Custom String: a,b,+,c,+,d,+,e,+,f,+,g,+,h,+,8,/ - i can change, but i dont know new value, im trying find on google, but i speak english bad and its hard for me. I hope, if here somebody can me help too.

[Roman777]

now i know what is CDEF - math function - but i dont know what i must use - can you help me pls?

thx

[argon0]

Hmmm, it may have been .87b it changed with...

I can't remember exactly what changed so can't tell you what to put in...

a,b,+,c,+,d,+,e,+,f,+,g,+,h,+,8,/

Is the correct cdef, and works with newer versions of Cacti (am using it still myself, despite having moved to using WMI for most things).

I wrote a brief tutorial a bit further up the thread - check that out first, if you have any specific questions I will try to answer them.

[Roman777]

ok, i find one function script - can you see on it and tell me better script who can show me all 8 cores? - this script show me all cores in one

(i mean if you can look to code and tell me what script is better for me - i dont understand this code )

Thx

See: http://forums.cacti.net/viewtopic.php?t ... c&start=15

That has my first shot at an 8cpu report. It has probably been superseded since then, but should still work.

If that doesn't work there should be several others in this thread..

BTW, please remember that to get any of "my" graphs to work you need to first graph each of the CPUs you want to include separately.

Good Luck

im trying export from 1 pc to second pc - but import is different and i dont know why - first computer have function graph (funkcni.jpg) and import second computer have nonfunction

all have "ucd/net - CPU Usage"

im trying delete graph and import from this forum - i have wrong too

[bmote]

Does anyone have a good summary aka how-to regarding this topic? I don't want a link to documentation. Documentation requires comprehension I just want to implement and administer.

I want to be able to add an AVERAGE CPU graph without a bunch of manual edits regardless of whether I have 2 or 20 CPUs.

I've imported the 4 cpu template. After selected all the cpu under the 'Data Query' section and click on 'Create' I get the follow error

ERROR: no Data Source associated. Check Template

Hi guys..
I have downloaded cacti_graph_template_multi_cpu_utilization_on_8_processor_box.xml
and follow the guide to apply the template.
But I'm getting the error below, can somebody help?
I still not able to display my 8 processor in this graph...

Kindly please advice.

What if "SNMP - Get Processor Information" isn't in the list of Associated data Queries?
Changing Host Template doesnt help

The cacti version is 0.8.7g

-- edit --
I have found an older version, I have export the data template and then import .
Seems to work up to this point

So far so good

Hi all,
i have a problem with the multi cpu template.
I want to set a threshold based on the mean cpu.
I need that cacti alert me when the mean between two cpu goes over 51%.
I have tried using the CDEF "Average All data sources - 2 sources" and with a custom cdef (a,b,+,2/) on a single data source (cause it doesn't exist a data source called Mean Cpu), but with no result.
For example on the first cpu i have passed the 70% and on the second cpu it arrived at 40%, the mean it's 55 but no email was sent.
There's a way to create a third data source based on the mean of the 2 cpu and set the threshold on it ?
Thanks in advance for your reply.

I haven't ever come across this, but will look into somepoint soon.

No, don't think you can do this. Would have to do the calculation prior to presenting the data to Cacti (i.e. in the data source/script) then so the threshold/alerting on that, I think.

Anyone ever do this for 24 cores?
2 processors 12 cores each I have snmp data for 24 processors.
Template to share?
