cacti monitoring pve virtual machine graphs is NaN

[div8cn]

cacti version: 1.2.2
pve version: 7.2
template: In/Out Bits (64-bit Counters) with Total Bandwidth


I opened and configured snmp on the pve host
cacti uses snmp to monitor the operation of the virtual machine on the pve host (mainly the vtep device)

When the tap (virtual machine network card) traffic is relatively small, such as 10Mbsp 100Mbsp, data collection, storage, and display are all normal;

When the tap traffic is large, >800Mbps, the image will always display Nan.

I analyzed the cacti.log and the rra file corresponding to the graph
It is found that spine has collected data from the pve host, and has not updated the data to the rrd file;

Does anyone know what is causing this problem?

Management-> Data sources -> choose any problematic -> What is Maxiumu value? Try increase or insert "U" if there is value smaller than 800Mbps

Management-> Data sources -> choose any problematic -> What is Maxiumu value? Try increase or insert "U" if there is value smaller than 800Mbps

Yes, the data source shows that it is 10000000. It should be caused by this problem;

I check data source's data source template="Interface - Traffic";


In the Interface - Traffic template, Maximum Value = 100000000000.
Enabled allow the user to override the value on the right during Data Source creation.


I use this data template to create a switch port flow diagram, the Maximum Value shown in the data source=10000000000;


I use this data template to create the virtual interface traffic map of the PVE host, and the Maximum Value shown in the data source=10000000;

Excuse me, where is my incorrect setting causing such a large gap in Maximun?

The template "Interface - Traffic", is the default setting when installing cacti, I didn't change it.

you should update to 1.2.24
