Azure Monitor provides comprehensive tools for monitoring the health and performance of your Azure-managed databases, including Azure Managed SQL, Azure Database for PostgreSQL, Azure Database for MySQL, and Azure Database for MariaDB. By following best practices, you can ensure effective monitoring and quickly identify and address potential issues.
Data Collection Configuration
- Enable platform metrics and diagnostics logs: Azure automatically collects platform metrics and diagnostics logs for most resources. Ensure these are enabled for your managed databases.
- Configure diagnostic settings: Use diagnostic settings to collect additional resource logs and send them to Azure Monitor Logs. This allows for detailed analysis and troubleshooting.
- Install Azure Monitor Agent (Optional): For Azure VMs hosting managed databases, consider installing the Azure Monitor Agent for deeper insights into host-level metrics and logs.
- Use Data Collection Rules (DCRs): DCRs enable centralized data routing from multiple sources to a single workspace. This simplifies management and analysis when monitoring various databases.
Monitoring Metrics
- Focus on critical metrics: Prioritize monitoring key metrics like CPU utilization, memory usage, storage consumption, transaction latency, and throughput.
- Set baselines and thresholds: Define baseline performance values for your database and configure alerts to trigger when thresholds are exceeded. This allows for proactive issue detection.
- Use metric alerts and notifications: Configure alerts to send notifications via email, SMS, or Azure Logic Apps when critical metrics exceed thresholds. This ensures timely response to potential problems.
Logs and Queries
- Analyze resource logs: Utilize Azure Monitor Logs for detailed analysis of diagnostics and resource logs. This provides insights into specific events and errors within your database.
- Create custom queries: Use Kusto Query Language (KQL) to create custom queries and filter logs based on specific criteria. This allows for focused analysis and troubleshooting.
- Use Log Analytics workspaces: Store and analyze logs in centralized Log Analytics workspaces for long-term data retention and advanced analysis capabilities.
Additional Best Practices
- Enable service health alerts: These alerts notify you of Azure service disruptions that might impact your databases.
- Implement automated monitoring: Use Azure Automation to collect data, run queries, and generate reports.
- Monitor database backups: Monitor your backup jobs to ensure successful completion and data integrity.
- Utilize Insights: Leverage built-in insights for everyday performance issues.
- Define roles and access control: Grant appropriate access permissions to different users and teams based on their roles and needs.
- Optimize costs: Utilize cost-effective storage solutions like Azure Blob Storage for long-term log retention.
- Monitor resource costs: Set alerts on cost limits to prevent unexpected charges.
