or did you mean with device id ?
of course, you need to add your -h <device_id>

Does some possibility exist to receive more often polling maybe after that the graph will be correct ?
You can do 1 min polling: https://docs.librenms.org/Support/1-Minute-Polling/
CAUTION: Be sure your librenms server and devices can do 1min polling!!
Did not have a chance to see your files, please use https://p.libren.ms/ .
That being said, 1 min polling is heavy for both librenms server and the polled devices, so do a few tests before running that in production.
Again, the issue here seems to be the way Cisco provides the SNMP value, averaged over 1 minute, compared to the way Cisco draws the GUI value. There is no way to define which one is right and which one is wrong unless you ask them.
Here is output for previous command
https://p.libren.ms/view/901d2fa1
Also i attached screen for previous day cpu utilization that seems to be wrong, because the graph didn’t reach point more than 10 %
In the capture above, here is the processor data replied by the device is 2%:

LibreNMS is using whatever value the switches supplies, if it doesn’t match the CLI, there is nothing we can do unfortunately…
So how do you think, increasing the polling time for 1 minute could resolve this problem ?
I am pretty sure it is not “as wrong” as you think it is. Just consider that the precision of the value is ± 10%. So you need to be informed it it goes to 80% (that is not good fir this kind of device to have 80% CPU). But from 0% to 40%, this is all right and you don’t have to worry about it.
ok, I got it
Also i want to ask about 2 problems that i have
When i use script ./validate.php i always receive this, after executing commands to fix this problem returns on the next day
And the second problem is Syslog from Cisco
I try to do it as written on the site, all was fine, but logs not coming
The tcpdump shows that data is coming from device but not shown
Please open a new message for these 2, will be easier for others to help you 
.
Bye
