Monitoring Kubernetes environment

RamNad 20

Hello,

I have a self-hosted K8S environment that I wanted to configure it to the Azure monitor or Azure-managed grafana. Currently, my cluster has been configured by installing metrics-server. How can I configure the data sources to visualize the data from my k8s cluster?

TIA

Hi RamNad,
Welcome to the Microsoft Q&A Platform! Thank you for asking your question here
To configure your self-hosted Kubernetes (K8s) environment with Azure Monitor or Azure-managed Grafana, let me help you with the steps,

Please ensure that below tools are available in your machine:
kubectl installed and configured to access your Kubernetes cluster.
Azure CLI installed on your machine.
We need to do enable the addons for monitoring

1.Use the following Azure CLI command to enable monitoring on your Kubernetes cluster. az aks enable-addons --addons monitoring --resource-group <ResourceGroupName> --name <ClusterName>

2.For self-hosted Kubernetes, you will use Azure Arc to onboard the cluster first. az connectedk8s connect --name <ClusterName> --resource-group <ResourceGroupName> --location <AzureRegion>

3.After onboarding the cluster to Azure Arc, you can enable monitoring: az monitor log-analytics workspace create --resource-group <ResourceGroupName> --workspace-name <WorkspaceName>

4.Now, link the Azure Monitor workspace to your self-hosted cluster: az monitor log-analytics workspace data-export create --resource-group <ResourceGroupName> --workspace-name <WorkspaceName> --name <ExportName> --table-name 'InsightsMetrics' --destination <StorageAccount>

We can configure Grafana for data visualization If you are using Azure-managed Grafana, follow these steps:

--In the Azure Portal, navigate to Azure Managed Grafana and create a Grafana instance.

--Once the instance is ready, open the Grafana dashboard.

Configure Prometheus as a data source:

--If Prometheus is not installed, install it in your Kubernetes cluster:

--Add Prometheus as a data source in Grafana using the following:

--In Grafana, go to Configuration > Data Sources.

Select Prometheus and enter the Prometheus service URL from your cluster

Thanks for your response!! I have k8s installed on a Cent-OS server, an azure VM. Still, it has to be connected as Azure Arc?

az connectedk8s connect --name <ClusterName> --resource-group <ResourceGroupName> --location <AzureRegion>

Hi RamNad,
Thanks for response,

Even though your Kubernetes (K8s) cluster is installed on a CentOS server running on an Azure VM, you'll still need to connect it to Azure Arc if you want to use Azure's tools for centralized management, monitoring, and security. Azure Arc treats any Kubernetes cluster running outside of Azure (on-premises, in other clouds, or even in Azure VMs) as external until it is connected.

Without connecting your K8s cluster to Azure Arc, Azure services like Azure Monitor, Azure Policy, and Azure Security won't be able to manage or monitor it. By connecting to Azure Arc, your cluster can be centrally managed within Azure.

You can use below comment for to connect your Kubernetes cluster to Azure Arc,az connectedk8s connect --name <ClusterName> --resource-group <ResourceGroupName> --location <AzureRegion>

To summarize:

If you want centralized management and access to Azure services like monitoring, security, and policy, you need to connect your K8s cluster to Azure Arc.

If you're using other tools or managing the cluster locally, you might not need to connect it to Azure Arc.
