Multi Core CPU monitoring WMI and Cacti 1.1.12

[maxcordan]

Hello colleagues!


I had a problem with the template for the CPU monitor on the server for each core separately. The template should display every 24 kernels as a separate line on my server.

Now I see the following:

сфсеш пкфзр.PNG (99.05 KiB) Viewed 1337 times

The data source in the graph is as follows:
PercentProcessorTime0 -> Total
PercentProcessorTime1 -> CPU1
PercentProcessorTime2 -> CPU2
PercentProcessorTime3 -> CPU3
...
...
...
PercentProcessorTime24 -> CPU24

After I turn on debug mode for this device:

cacti log.PNG (230.08 KiB) Viewed 1337 times

(Yes, I create 2 graphs for monitoring single CPU, but I see the same outputs on the graph)

After I set parameter in "Generic Log Level" as "DEBUG" I see the following:

cacti debug.PNG (81 KiB) Viewed 1337 times

(I do not have charts with more than 10 cores (except for this), so I can conclude that this part of the debug applies to this graph)

I have installed Cacti 1.1.12.

In Cacti 1.1.5, a similar problem was not observed. All 24 cores were recovered. Judging by the output debug, I can conclude that Cacti "forgot" to read long lines. I checked that the number of characters with the output of PercentProcessorTime14: * inclusive, is 505 characters.

In Technical Support I have following:

cactits2.PNG (109.43 KiB) Viewed 1337 times

Please help with this. I want look all cores on my graph
Are you have any ideas?

Does the server in question have the latest snmpd running?

Can you manually query the OID that Cacti is showing NaN values on the graph?

Thank for answer!

I get information over WMI. not SNMP.
