[ZBX-22562] Kubernetes Kubelet by HTTP not collecting data from Windows pod Created: 2023 Mar 21  Updated: 2023 Mar 22

Status: Confirmed
Project: ZABBIX BUGS AND ISSUES
Component/s: Documentation (D), Templates (T)
Affects Version/s: 6.0.14
Fix Version/s: None

Type: Incident report Priority: Trivial
Reporter: Avraham Eisen Assignee: Zabbix Integration Team
Resolution: Unresolved Votes: 0
Labels: None
Remaining Estimate: Not Specified
Time Spent: Not Specified
Original Estimate: Not Specified
Environment:

Azure Kubernetes Service with a Linux node cluster and a Windows node cluster where the pod for the application is also running Windows


 Description   

Steps to reproduce:

  1. Execute pre-requisites for the Kubernetes Template
  2. Allow Kubelet discovery to run

Result:
The cadvisor items for the Windows pod (CPU: Load average, 10s, CPU: System seconds, total, and CPU: User seconds, total) does not return any data.
Expected:
There's no Zabbix documentation, whether in the README of the Git repo for the template or the documentation URI, to say whether the Zabbix Kubernetes templates or its dependencies (kube-state-metrics, etc.) support a Windows node cluster or a Windows pod.  I have no way to determine whether the current state of the Zabbix Helm Charts deployment does not support monitoring Windows pods, making this expected, or whether this should be working and is an actual issue.

 

My expectation is, minimally, that any nuances of the Zabbix-provided templates to monitor Kubernetes mention whether Windows nodes, pods, and containers are supported or not
