Upgrading and Monitoring Azure AKS Kubernetes Cluster #Azure #AKS #ContainerInsights

Microsoft Azure AKS Kubernetes Cluster

Azure Kubernetes Service (AKS) makes it simple to deploy a managed Kubernetes cluster in Azure. AKS reduces the complexity and operational overhead of managing Kubernetes by offloading much of that responsibility to Azure. As a hosted Kubernetes service, Azure handles critical tasks like health monitoring and maintenance for you. The Kubernetes masters are managed by Azure. You only manage and maintain the agent nodes.

When you go to settings of your Azure AKS Kubernetes Cluster and then to Upgrade, there you can see your version of Kubernetes and the New versions of Azure AKS Services. Before you upgrade :

  • Important : Never skip an Upgrade version of Azure AKS Kubernetes.

Here you find all the information about Azure AKS Kubernetes Change Log on GitHub 

You can Upgrade from here by clicking on version 1.15.5 and click on Save at the top.

Azure Activity log.

When the first upgrade is succeeded you can do the next version upgrade.

With Azure Monitoring Insights you can view the live data and see what’s going on.

To Upgrade your AKS Services via Microsoft Azure CLI

As a DevOps person you like to work with Microsoft Visual Studio Code
Deploying and managing your Azure AKS Kubernetes Cluster services from there with the right extensions.

Here you see also that the KubeProxyVersion is v1.15.7

The extension for developers building applications to run in Kubernetes clusters and for DevOps staff troubleshooting Kubernetes applications.

Features include:

  • View your clusters in an explorer tree view, and drill into workloads, services, pods and nodes.
  • Browse Helm repos and install charts into your Kubernetes cluster.
  • Intellisense for Kubernetes resources and Helm charts and templates.
  • Edit Kubernetes resource manifests and apply them to your cluster.
  • Build and run containers in your cluster from Dockerfiles in your project.
  • View diffs of a resource’s current state against the resource manifest in your Git repo
  • Easily check out the Git commit corresponding to a deployed application.
  • Run commands or start a shell within your application’s pods.
  • Get or follow logs and events from your clusters.
  • Forward local ports to your application’s pods.
  • Create Helm charts using scaffolding and snippets.
  • Bootstrap applications using Draft, and rapidly deploy and debug them to speed up the development loop.

Upgrade Azure AKS Kubernetes Services is Done 😉

When you manage and monitor your Azure AKS Kubernetes Cluster Services, have also a look at Microsoft Azure Advisor for new features and security issues :

Azure Advisor recommendations for Kubernetes services.

The cool thing is that Microsoft also give you the solution to solve a high risk :


Remediation steps.

Conclusion :

Microsoft Azure AKS Kubernetes is a managed services and made upgrading for customers really easy to do. You can monitor the upgrades and see the Health status of the Azure AKS Kubernetes services. You get free advise to improve the Services and this all keeps you in control and your business running.

Windows Admin Center Rocks for Managing Hybrid DataCenters #WAC #Azure #Winserv

Microsoft Windows Admin Center for Hybrid IT Management

I really like to work with Microsoft Windows Admin Center for managing my Hybrid workloads Windows Servers in Azure Cloud Services but also our On-premises Servers on Hyper-V and VMware platform. Even our physical Windows Servers can be managed from Windows Admin Center.

You can extend on-premises deployments of Windows Server to the cloud by using Azure hybrid services. These cloud services provide an array of useful functions, including the following:

  • Protect virtual machines and use cloud-based backup and disaster recovery (HA/DR) with Azure Site Recovery.
  • Track what’s happening across your applications, network and infrastructure with the help of advanced analytics and machine learning in Azure Monitor.
  • Simplify network connectivity to Azure with Azure Network Adapter.
  • Keep virtual machines up to date with Azure Update Management.

Azure hybrid services work with Windows Servers in the following configurations:

I’m working with Windows Admin Center since day one, and you see the hybrid management tool evolving with great new features to make your life as an Administrator more easier. For example you get notifications when there are updates in extensions.

Notification details about update Extensions

When you click on the link “Go to Extensions” you will see the Extensions installed and the Updates which you can install from there.

Here you see an Azure Security Center Extension update.

There are not only Microsoft extensions, but also third party solution extensions and you could build your own extension for your solution. Here you find all the information about Windows Admin Center Extensions

Third Party Windows Admin Center Extensions

Installing a New extension is easy to do, the Azure Cloud Shell (Preview) was the last extension I installed in my Azure MVP Lab to work with. Azure Cloud Shell is an interactive, authenticated, browser-accessible shell for managing Azure resources. It provides the flexibility of choosing the shell experience that best suits the way you work, either Bash or PowerShell. Cloud Shell enables access to a browser-based command-line experience built with Azure management tasks in mind. So how does this look in Windows Admin Center?

Install the Azure Cloud Shell (Preview) Extension

You find the Installed Azure Cloud Shell in the pulldown menu of WAC

Copy your code here https://microsoft.com/devicelogin

You will see this screen when you copy-paste the code

When you go back to Windows Admin Center you will see you are connected with Azure Cloud Shell CLI 😉

Azure Cloud Shell in Windows Admin Center

from here you can manage all your Azure Cloud Services via the Azure Cloud Shell CLI with Bash or Powershell.
Here you find more about Microsoft Azure Cloud Shell tools and Features.

you can add an Azure Network Adapter to your on-premises servers to help you securely connect the server to an Azure Virtual Network.

Read more about adding Microsoft Azure Network Adapter (Preview) in the top 10 Features of Windows Server 2019. Nice link speed of 40 Gbps 😉

For Management of your Windows Servers you need some tools and consoles. Windows Admin Center is supporting you to get the Management consoles in one place to do your administration and updates.
The next tree Features are in Windows Admin Center to manage your Windows Server.

Powershell inside WAC of my Domain Controller

Windows PowerShell is a task-based command-line shell and scripting language designed especially for system administration. Built on the .NET Framework, Windows PowerShell helps IT professionals and power users control and automate the administration of the Windows operating system and applications that run on Windows.
Here you find more information about Windows Commands

Windows Update in Windows Admin Center.

Of course you need to update your Windows Servers, and what I like in WAC is that you get the information if an update needs a reboot before you click on Install Updates. This option is good for my Azure MVP Lab but when you need to update more then 100 Servers, you would do that centrally managed like with Update Management solution in Azure

Windows Remote Desktop in WAC

Remote Desktop is one of the Features of Windows Admin Center, to take over the desktop for installations of Applications for example.

Windows Admin Center got a lot more Features and Tools to Manage your Windows Servers in a Hybrid world.
Like these :

  • Storage
  • Security
  • System Insights
  • Scheduled Tasks
  • Installing Roles and Features of Windows Server
  • Registry
  • Processes running on your Windows Server
  • Managing and deploying Clusters
  • and much More………

You can install the following Resources to Manage with WAC

Windows Admin Center Overview

Conclusion:

Microsoft Windows Admin Center is the New Management tool for your Hybrid IT Management to Controle your Servers for your Business. It got all the Management consoles covered of Windows Servers to manage from one tool.
It’s easy to use and It keeps you Up-to-date of what is happening on your Windows Server but also what is New and updated. With Microsoft Windows Admin Center your are learning on the job and that’s what I Like 😉
Hope you will use Microsoft Windows Admin Center too for your Business, download it here for Free!

Full Screen Monitoring

When you install Azure Virtual Machines or Kubernetes Clusters in the Microsoft Cloud, It’s important to monitor your workload and keep your IT department in Control for the Business. Metric alerts in Azure Monitor work on top of multi-dimensional metrics. These metrics could be platform metrics, custom metrics, popular logs from Azure Monitor converted to metrics and Application Insights metrics.

When you have important alerts, you want to take action based on your rules.

Take action on Alerts

Make your Own rules based on Alerts.

IT Department of a company has most of the time different teams with each having it’s own responsibility of workloads in the Microsoft Cloud. For example, the Servicedesk is supporting the Business and they like to see if all the Services are up and running for the Business. The Infrastructure Team wants the same, but on deep level components of the Services like Memory, Network, Storage, CPU, Performance, Availability and more. The Technical Application Team is interested if the application is running and working with all the Interfaces, Databases, and/or Azure Pipelines.

Each Team can build there own Azure Dashboard(s) in the Microsoft Cloud.

Here I Have made an easy example of my Windows Server 2019 Virtual Machines and my Azure Kubernetes Cluster in One Microsoft Azure Dashboard :

You can Start from Azure Monitor Metrics

Or you can Start from the Virtual Machine Blade here.

When you have your Azure Monitor metrics ready with the right information then you can create it in your Azure Dashboard for your Team.

 

Select another Dashboard.

Create your Own Dashboard.

Now we have the first VM with CPU percentage in the Azure Dashboard.

Here I have added More Virtual Machines to the Same Metric Chart.

When you have Azure Kubernetes Cluster to monitor :

From here you can Add Container Insights information into your Azure Dashboard :

Adding Azure Monitor Container Insights of KubeCluster01

Azure Monitor for containers is a feature designed to monitor the performance of container workloads deployed to either Azure Container Instances or managed Kubernetes clusters hosted on Azure Kubernetes Service (AKS). Monitoring your containers is critical, especially when you’re running a production cluster, at scale, with multiple applications.
Azure Monitor for containers gives you performance visibility by collecting memory and processor metrics from controllers, nodes, and containers that are available in Kubernetes through the Metrics API. Container logs are also collected. After you enable monitoring from Kubernetes clusters, these metrics and logs are automatically collected for you through a containerized version of the Log Analytics agent for Linux and stored in your Log Analytics workspace.

How to monitor your #Kubernetes clusters – Best Practices Series #AKS #AzureMonitor

Get best practices on how to monitor your Kubernetes clusters from field experts in this episode of the Kubernetes Best Practices Series. In this intermediate level deep dive, you will learn about monitoring and logging in Kubernetes from Dennis Zielke, Technology Solutions Professional in the Global Black Belts Cloud Native Applications team at Microsoft.

Multi-cluster view from Azure Monitor

Azure Monitor provides a multi-cluster view showing the health status of all monitored AKS clusters deployed across resource groups in your subscriptions. It shows AKS clusters discovered that are not monitored by the solution. Immediately you can understand cluster health, and from here you can drill down to the node and controller performance page, or navigate to see performance charts for the cluster. For AKS clusters discovered and identified as unmonitored, you can enable monitoring for that cluster at any time.

Understand AKS cluster performance with Azure Monitor for containers

Container Live Logs provides a real-time view into your Azure Kubernetes Service (AKS) container logs (stdout/stderr) without having to run kubectl commands. When you select this option, new pane appears below the containers performance data table on the Containers view, and it shows live logging generated by the container engine to further assist in troubleshooting issues in real time.
Live logs supports three different methods to control access to the logs:

AKS without Kubernetes RBAC authorization enabled
AKS enabled with Kubernetes RBAC authorization
AKS enabled with Azure Active Directory (AD) SAML based single-sign on

You even can search in the Container Live Logs for Troubleshooting and history.

#Microsoft Azure Monitor and Service Map Insights workbooks (Preview) #Azure #Cloud

Azure Monitor for VMs monitors your Azure virtual machines (VM) and virtual machine scale sets at scale. The service analyzes the performance and health of your Windows and Linux VMs, monitoring their processes and their dependencies on other resources and external processes.
As a solution, Azure Monitor for VMs includes support for monitoring performance and application dependencies for VMs that are hosted on-premises or in another cloud provider. Three key features deliver in-depth insight:

  • Logical components of Azure VMs that run Windows and Linux: Are measured against pre-configured health criteria, and they alert you when the evaluated condition is met.
  • Pre-defined, trending performance charts: Display core performance metrics from the guest VM operating system.
  • Dependency map: Displays the interconnected components with the VM from various resource groups and subscriptions.

The features are organized into three perspectives:

Health
Performance
Map

Here we have a look at Azure Monitor Service map of my local machine :

Here in the Event you see two Configuration Changes.

What is awesome to see, when you double click on the link marked with a arrow, then It will start log analytics with the right query to see what those changes are 🙂

Monitoring Azure Kubernetes Cluster

Azure Monitor for containers is a feature designed to monitor the performance of container workloads deployed to either Azure Container Instances or managed Kubernetes clusters hosted on Azure Kubernetes Service (AKS). Monitoring your containers is critical, especially when you’re running a production cluster, at scale, with multiple applications.
Azure Monitor for containers gives you performance visibility by collecting memory and processor metrics from controllers, nodes, and containers that are available in Kubernetes through the Metrics API. Container logs are also collected. After you enable monitoring from Kubernetes clusters, these metrics and logs are automatically collected for you through a containerized version of the Log Analytics agent for Linux and stored in your Log Analytics workspace.

Here you find awesome documentation about Understanding AKS cluster performance with Azure Monitor for containers

What I really like is that you now can see the Container Live logs from the Azure portal and see what is going on in the background of a Container 🙂

Activate Azure Kubernetes Container Live Logs

Here you see the Container Live logs

This feature provides a real-time view into your Azure Kubernetes Service (AKS) container logs (stdout/stderr) without having to run kubectl commands. When you select this option, new pane appears below the containers performance data table on the Containers view, and it shows live logging generated by the container engine to further assist in troubleshooting issues in real time.
Live logs supports three different methods to control access to the logs:

  1. AKS without Kubernetes RBAC authorization enabled
  2. AKS enabled with Kubernetes RBAC authorization
  3. AKS enabled with Azure Active Directory (AD) SAML based single-sign on

You even can search in the Container Live Logs for Troubleshooting and history :

Search on ssh

Azure Monitor for containers uses a containerized version of the Log Analytics agent for Linux. After initial deployment, there are routine or optional tasks you may need to perform during its lifecycle.
Because of this agent you can work with Log Analytics in Azure Monitor :

Log Analytics on Containers.

Here you find more on Log Analytics query language

Conclusion :

When you have your production workload running on Azure Kubernetes Clusters, It’s important to monitor to keep you in Control of the solution in Microsoft Azure and watch for improvements like performance for the business. With Container Live logs you can see what is going on in the Containers when you have issues and that’s great for troubleshooting to get your problem solved fast. Get your workload into Azure Containers and make your Azure DevOps CI/CD Pipelines in the Cloud.
