How to configure and enable Kubernetes Monitoring using Zabbix?

• Method 1 – Using Zabbix in Kubernetes Template
• Method 2 – Using prometheus operator in Kubernetes clustor & Zabbix Integration with prometheus
• Method 3 – Using Zabbix operator – Under Developement

Method 1 – Using Zabbix in Kubernetes Template

Step 1 – Setup a Kubernetes Clustor

Step 2 – How Kubernetes Monitoring Works?

All the moniotring is done using

• Docker – Its a running deamon, you can find in each host
• Kubelet – Its a running deamon, you can find in each host
• API of Kubernetes Components such API server,Controller manager, Scheduler etc

Step 3 – Understand How to fetch metrices from API in Kubernetes?

You need 2 information

• API Adress(URL). ie. {$KUBE.API.SERVER.URL}
• Access (Password – Token – Certificate). ie. {$KUBE.API.TOKEN}

Step 4 – Decice what you want to monitor? Choose a template accordingly.

• Kubernetes API server by HTTP
• Kubernetes cluster state by HTTP
• Kubernetes Controller manager by HTTP
• Kubernetes kubelet by HTTP
• Kubernetes nodes by HTTP
• Kubernetes Scheduler by HTTP

Step 5 – Add Host in Zabbix and Choose Kubernetes template and Set your template Macros as the per setup

Method 2 – Using prometheus operator in Kubernetes clustor & Zabbix Integration with prometheus

• prometheus is written in golang
• kubernetes is written in golang
• prometheus is a cncf project like kubernetes
• prometheus integ with kubernetes is very powerful compare to all
• To monitor kubernetes, prometheus has kubernetes operator which is very powerful and easy
