Azure Arc: Solving Re-onboarding Challenges with a New Tool

Kaido Jarvemets — Wed, 02 Oct 2024 08:58:44 +0000

Managing hybrid and multi-cloud environments with Azure Arc can be complex. I've noticed a common issue: the need to re-onboard a server when problems occur.

Here's a scenario I've encountered: An Azure Arc-enabled server starts misbehaving. Extensions refuse to update, PowerShell commands fail, and the Azure portal becomes unresponsive. Many of us end up deleting and re-adding the Azure Arc object, risking the loss of important configurations.

To tackle this challenge, I've developed a new tool: the Azure Arc Re-Onboarding Assistant. My utility helps with:

Backing up Azure Arc server configurations
Guiding users through server offboarding
Assisting with re-onboarding
Automatically restoring settings

With this tool, I've found that administrators can maintain their server configurations, including tags, data collection rules, and endpoint settings, even during a full re-onboarding process.

As I've seen Azure Arc usage grow, I believe tools like this become increasingly valuable for keeping operations smooth in complex environments.

Have you faced re-onboarding issues with Azure Arc-enabled servers? What approaches have you used to solve them? I'd love to hear about your experiences in the comments!

The 1 Azure Arc Setting You Can't Ignore: config.mode

Kaido Jarvemets — Wed, 10 Jul 2024 09:09:58 +0000

By default, Azure Arc allows all extensions on your Azure Connected Machine Agent - this is known as full mode. As an administrator, you should consider changing this setting based on your specific needs. Understanding the config.mode property is important, as switching to monitoring mode will impact your management capabilities.

This Azure Arc setting adjusts how the Azure Connected Machine Agent operates. Proper configuration improves Azure Arc server management across hybrid infrastructures.

Azure Arc and config.mode: Key Points

The config.mode property in Azure Arc affects:

Security: Control which agent capabilities are active in different environments.
Management Scope: Determine the level of interaction possible with your servers.
Compliance: Align with your organization's policies on remote management.

Azure Arc Agent Modes Explained

1. Full Mode in Azure Arc

Enables all features: extensions, guest configuration, remote connectivity.
Suitable for extensive Azure Arc server monitoring and management.

2. Monitor Mode in Azure Arc

Limits to monitoring-specific extensions.
Turns off guest configuration and remote tools.
Appropriate for high-security Azure Arc environments or basic monitoring needs.

Setting Up Azure Arc Agent Modes

Use azcmagent to set the mode in your Azure Arc deployment:

# Set full mode
azcmagent config set config.mode full

# Set monitor mode
azcmagent config set config.mode monitor

Simplifying Azure Arc Agent Management with Custom PowerShell Module

Kaido Jarvemets — Fri, 05 Jul 2024 07:15:56 +0000

I'm happy to share a tool I've developed to streamline Azure Arc Connected Agent management. As many of you know, managing Azure Arc agents can be complex, especially in large-scale deployments. That's why I created the AzureArcConnectedAgentManagement PowerShell module.

Why This Module?

While Microsoft offers a PowerShell module for Azure Arc, it primarily focuses on onboarding. My module complements this by providing comprehensive local agent management capabilities.

Key Features:

15 custom commands for day-to-day administration
Simplified interface for azcmagent.exe utility
Enhanced user experience for common tasks

Some Useful Commands:

Connect-AzureArcNode
Get-AzureArcNodeAgentInformation
Test-AzureArcNodeConnection
Save-AzureArcNodeLogs

You can find the full module on PowerShell Gallery. It's designed to make your life easier when managing Azure Arc across your infrastructure.

Important Note: This is the first release, so there might be some bugs. Let me know if something is not working!

Happy Arc Management and Scripting! 🚀
