The nodes are discovered but without data, but no pods are discovered at all.

Thanks for your bug report. I'm sorry that you have problems.
I reformatted your bug report to make it more readable.

You would probably have to delve deeper into the analysis of the problem yourself, as I currently do not have an Azure environment available.

The information provided is a bit too scarce to understand exactly what went wrong. It could be that k8s-zabbix has too few rights, but it could also be that certain structures of this Kubernetes no longer match AKS.

To find out, I recommend that you run the project locally and adjust the config so that you get the details.

The following parameters can help you in the configuration:
(see https://github.com/zabbix-tooling/k8s-zabbix/blob/master/config-dev.ini)

debug = False
debug_k8s_events = False
# this excludes all ressources, remove the one you want to debug
resources_exclude = components, statefulsets, daemonsets, nodes, services, pvcs, deployments

For the node error:
it's because the k8sobject denies None namespace.
In this PR this issue is adressed:
#24

I also addressed the division by zero by checking first
