Troubleshooting Azure Virtual Machine Issues
This section provides guidance on troubleshooting common issues you might encounter while working with Azure Virtual Machines. It covers a range of problems, from connectivity issues to performance bottlenecks and error messages.
Common Issues
- Connectivity Problems: Ensure your network configuration is correct and that your firewall allows traffic to the VM.
- Performance Issues: Monitor CPU, memory, and disk I/O to identify performance bottlenecks.
- Error Messages: Use the error messages as a starting point for diagnosis, and consult the Microsoft documentation for specific error codes.
- Startup Issues: Check the VM's boot logs for errors during startup.
Diagnostic Tools
Azure provides several tools to help you diagnose and troubleshoot VM issues:
- Azure Portal: Use the Azure Portal to monitor VM performance and check diagnostic logs.
- Azure Network Watcher: Use Network Watcher to troubleshoot network connectivity issues.
- Azure Site Recovery: If you are using Azure Site Recovery, check the replication status.
// Example: Azure Portal - Monitor VM Metrics
// Navigate to the VM in the Azure Portal
// Select "Monitoring" -> "Metrics"
// Review CPU, memory, and network usage.
