How ALAR Works

ALAR consists of two components:

  • Monitoring Agent: Installed on each VM, it monitors system metrics and logs for potential issues.
  • Repair Service: A cloud-based service that analyzes data from the monitoring agent and triggers repairs when necessary.

ALAR identifies issues based on pre-defined rules and applies corresponding repairs. For example, it can restart services, update packages, or reconfigure network settings.

Benefits of ALAR

  • Improved Availability: ALAR proactively repairs issues, reducing downtime and improving VM availability.
  • Reduced Administrative Burden: Automates repair processes, freeing up administrators to focus on other tasks.
  • Increased Security: Timely repairs address vulnerabilities and enhance VM security.
  • Cost Savings: Reduces the need for manual repairs, saving on administrative costs.

Supported Issues

ALAR currently supports repairs for a wide range of issues, including:

  • System crashes
  • Service failures
  • Kernel panics
  • Network connectivity issues
  • Package update failures

Configuration and Usage

ALAR is enabled by default on new Azure Linux VMs. To manually enable or disable ALAR, use the Azure portal or Azure CLI. You can customize the repair rules and behavior using the ALAR configuration file.

What is Azure Linux Auto Repair (ALAR)?

Azure Linux Auto Repair (ALAR) is a service that automatically repairs common Linux boot issues in Azure virtual machines (VMs). It helps ensure that your VMs are always up and running, without the need for manual intervention.

What types of boot issues does ALAR fix?

ALAR can repair a variety of common Linux boot issues, including:

  • Kernel panics
  • Filesystem errors
  • Missing or corrupt boot files
  • Incorrect boot configuration
