Database connectivity issues can disrupt critical applications and lead to downtime, impacting business operations. But how do you quickly diagnose and resolve these issues in Azure SQL Database?
Azure SQL Resource Health provides real-time status updates and troubleshooting insights, helping you determine whether connectivity failures are due to Azure outages, maintenance, or database misconfigurations.
In this post, we’ll explore:
✔️ What Azure SQL Resource Health is
✔️ How to use it to troubleshoot database connectivity
✔️ Best practices for minimizing downtime
What is Azure SQL Resource Health?
Azure SQL Resource Health is a diagnostic tool that provides real-time visibility into the health of your Azure SQL Database, indicating whether your database is:
🔹 Available – Fully operational and healthy.
🔹 Degraded – Experiencing performance or connectivity issues.
🔹 Unavailable – Completely unreachable due to a failure or maintenance.
🔹 Unknown – Health status is temporarily unavailable.
Resource Health helps answer key troubleshooting questions, such as:
✅ Is my database down due to an Azure outage?
✅ Is Azure performing maintenance on my SQL instance?
✅ Is the connectivity issue related to my own network settings?
How to Check Azure SQL Database Resource Health
1️⃣ Using Azure Portal
- Go to Azure Portal → Navigate to Azure SQL Database.
- Select your SQL Database instance.
- In the left panel, click Resource Health under Support + troubleshooting.
- Review the health status and any reported issues or maintenance events.
2️⃣ Using Azure CLI
For command-line users, check the health of an Azure SQL Database using:
az resource health show --resource-id "/subscriptions/{subscription-id}/resourceGroups/{resource-group}/providers/Microsoft.Sql/servers/{server-name}/databases/{database-name}"
This returns JSON output detailing the database health status.
3️⃣ Using PowerShell
Run this PowerShell script to check the database health status:
Get-AzResourceHealth -ResourceId "/subscriptions/{subscription-id}/resourceGroups/{resource-group}/providers/Microsoft.Sql/servers/{server-name}/databases/{database-name}"
If the status is Degraded or Unavailable, follow the recommended remediation steps in Azure Portal.
Common Causes of Azure SQL Connectivity Issues & Fixes
| Issue | Resource Health Status | Solution |
|---|---|---|
| Azure outage or failure | Unavailable | Wait for Microsoft to restore service. Monitor status at Azure Status. |
| Planned maintenance | Unavailable | Review Azure notifications in the portal. |
| Firewall rules blocking access | Available | Update firewall settings to allow client IPs. |
| VNet or Private Link misconfiguration | Available | Verify Private Endpoint settings and DNS resolution. |
| Long-running queries causing timeout | Degraded | Optimize queries, check indexing, and scale database resources. |
| Connection pool exhaustion | Degraded | Reduce idle connections or increase connection limits. |
| Geo-replication failover | Degraded | Check failover status and update connection strings. |
Best Practices for Preventing Connectivity Issues
✔️ Monitor Resource Health regularly – Detect and resolve issues proactively.
✔️ Set up Azure Alerts – Get notified of performance degradation or downtime.
✔️ Use Active Geo-Replication – Ensure high availability by setting up failover regions.
✔️ Check firewall & network settings – Ensure proper IP whitelisting and VNet configurations.
✔️ Optimize queries & indexes – Prevent timeouts due to inefficient queries.
✔️ Implement retry logic in applications – Automatically handle transient connection failures.
Conclusion
Azure SQL Resource Health is a powerful troubleshooting tool that helps identify connectivity issues, Azure outages, and database failures in real time. By proactively monitoring database health, configuring alerts, and optimizing network settings, you can minimize downtime and ensure high availability.
