ucd/net CPU Usage - NaN Value

[CamZie]

Hello everyone,

We have recently upgraded our Cacti installation from 0.8.8 (Debian 9) to version 1.2.2 (Debian 10) and after that we had issues with the "ucd/net CPU Usage" graph.

The devices affected are virtual servers with 6 virtual CPUs and is running many docker containers.

System/Software version where Cacti is installed:

• OS: Debian 10

• cacti: 1.2.2+ds1-2+deb10u5

• cacti-spine: 1.2.2-1

• PHP version: 7.3

We have also tested with the a newer version 1.2.16 (Debian 11) with cmd.php as Poller and same issue. In the attachment you will find an example of the graph with "NaN" values:

• ucd/net CPU Usage (enhanced)

Does anyone have any idea? Thanks in advance!

1.2.2 is very old. Please update to 1.2.24
