Steps to reproduce:

Graphs of Discovery rule 'Template OS Linux: Network interface discovery' are empty.

Result:

Graphs are empty

Expected:
See network graphs with values

Note:

We have this problem since version 6.0.14 or 6.0.15.

Currently, we are using:

• zabbix_server 6.0.21 
• zabbix_agent2 6.0.19, 6.0.20, 6.0.21

I provided some screenshots of my screenshots of my setting. I 'tested' the Discover rule and the template, the discovery rule returns a result, and the template result returns 'Cannot find information for this network interface in /proc/net/dev.', but I can run 'cat /proc/net/dev' on the client without any problem.

Is there something else I could provide?

I am already aware of this ticket, but an update of the version did not solve the problem: https://support.zabbix.com/browse/ZBX-22627
