Multi CPU Utilization Graph

Aha! Have I found it? Perhaps.

I went into "Graph Templates" and edited the "Multi CPU Utilization on 4 Processor Box (v2)" graph. I clicked on each of the "Graph Item Inputs" and assigned them to one of the LINE1 items (items #5,9,13,17).

Then I was able to save the graph details

Actually, not just for the LINE1 bits, but for all 4.

Data Source [cpu0]
Item #5: LINE1 (AVERAGE)
Item #6: GPRINT (LAST)
Item #7: GPRINT (MIN)
Item #8: GPRINT (MAX)

Data Source [cpu1]
Item #9: LINE1 (AVERAGE)
Item #10: GPRINT (LAST)
Item #11: GPRINT (MIN)
Item #12: GPRINT (MAX)

etc

I'm still having the graph math problem.

(1+2+3)/3 !=2.5

I don't know where this graph is pulling some of the numbers that it has to generate some of the answers that it does. I like this graph and it would suck not to be able to use it because it's adding something to the numbers it polls.

Hopefully someone can help.

Thanks.

MoreDakka,

I suspect your Mins and Maxs are happening at different times on each of the processors - thus the mean Max will be lower than the mean of the Maxs. That's probably clear as mud ....

In other words, the mean Max shown is the highest MEAN that has been attained - it's just that one or two of the processors took it high at a particular sample. At another sample, different processors might be higher, and the mean still be lower than the existing Max for the mean.

If that still doesn't make sense, try looking at the graphs for each individual processor, and notice that they don't all peak at the same sample. Then run the numbers for the avg at each sample that appears to be the largest.

Trying to graph 2 CPU's...

suse enterprise 10 linux(2.6.16 kernel)
cacti 0.8.6j + patches

net-snmp = 5.3.0.1-25.2

Hi all

I can´t make this graph work on cacti 0.8.7.because I cant get individual graphs for each cpu.

I am using a host template that has a associated data query called "1) SNMP - Get Processor Information". when I add a device and asign that template to the host I get this:

but when I go to "create graph for this host" i get:

and when I run on debug mode I get:

¿does anyone knows how to to solve this?? ¿any clue? ¿maybe I have to modify the config of the snmp server on the host?? I think that´s not the problem because looking the code at the script ss_host_cpu.php I think the OID is .1.3.6.1.2.1.25.3.3.1 and when I run this it seems ok

$ [root@gen30 scripts]# snmpwalk -v2c -cpublic localhost .1.3.6.1.2.1.25.3.3.1
HOST-RESOURCES-MIB::hrProcessorFrwID.768 = OID: SNMPv2-SMI::zeroDotZero
HOST-RESOURCES-MIB::hrProcessorFrwID.769 = OID: SNMPv2-SMI::zeroDotZero

can anyone confirm if this config is ok??

I also tried to change the graph tempate to ucd/net - cpu usage on the last capture and still fails. ¿any clue to solve this??

Im running cacti 0.8.7 on centos5 x86_64 and monitoring some centos5 and debian etch machines.
many thanks in advance for any help

Yoy have this CDEF's ?

At me it work perfectly

I now export template witch dependency. Try its.

It works fine. Thanks a lot.
One question : have you the template for 16 box CPU ?

Bye

slech · Cacti User Joined: 06 Nov 2007 Posts: 90

no

i don't have servir with 16 cpu box.
But bballard create 16 cpu template.
Try it
