What are the best practices for monitoring SQL Server high availability?

Conduct routine checks on server health, including disk space, memory usage, and CPU utilization, to catch any issues early. Monitor regularly.

Monitoring SQL Server high availability is crucial to ensure that your databases are always available and performing optimally. 1. Set up alerts for critical events like failovers. 2. Monitor performance metrics: CPU, memory, disk I/O, network. 3. Monitor database mirroring and AlwaysOn Availability Groups. 4. Use automated monitoring tools like SQL Server Management Studio (SSMS) and SQL Server Agent Alerts. 5. Perform regular health checks and test failover scenarios. 6. Monitor disk space and replication status.

Utilizar ferramentas para monitoria de terceiros/integradas ao SQL, como o Management Studio, p/monitorar desempenho e disponibilidade. Testar failover regularmente para garantir que mecanismos de alta disponibilidade, como o AlwaysOn Availability Groups, est?o ok. Monitorar o espa?o, tanto do SO quanto dos BD, para evitar problemas de falta de espa?o que possam comprometer a disponibilidade do SQL. Realizar backups e validar sua integridade, garantindo dados disponíveis em caso de falhas. Monitorar o desempenho das consultas e identificar gargalos d desempenho q possam impactar no SQL Implementar políticas de manuten??o regular, como indexa??o de BD e otimiza??o de consultas, para garantir a alta disponibilidade e desempenho SQL.

Test and implement failover strategies to minimize downtime in case of server failure. Regularly simulate failover scenarios to validate their effectiveness.

Regularly validate backups to ensure data integrity and readiness for recovery. Test restoration procedures to verify that backups are viable in case of emergencies.

Monitor performance trends over time to identify potential bottlenecks or areas for optimization. Utilize tools to track query performance, index usage, and resource contention.

Database Activity Monitoring (DAM) system must detect anyone, inside or outside the organization, accessing or tampering with information in any database-driven applications that handle personal, financial, HR, or other business.The monitoring system will collect metrics such as syntax errors, denials of access, permission changes and unusual access patterns, and then aggregate them, and report on them.It is quite separate from, and independent of, any defensive techniques to prevent attack. The aim is to be immediately aware if this layer of defense has been avoided, sidestepped or penetrated, and to detect any unusual activities on the server, including database read and update activity, server or database settings, or permission changes.

Implement robust security measures and monitor for any suspicious activity or unauthorized access. Regularly review access controls and audit logs to detect and mitigate security threats.

Maintain up-to-date documentation of your SQL Server high availability configuration, including failover procedures, network configurations, and disaster recovery plans. Regularly review and update documentation to reflect any changes or enhancements made to your SQL Server environment.

Maintain up-to-date documentation of your SQL Server configuration, including high availability setup, failover procedures, and backup schedules. Regularly review and update documentation to reflect any changes or enhancements.

Additionally, consider factors such as network latency, latency between servers in a replication topology, and monitoring/alerting thresholds. Stay informed about new features and updates from Microsoft to leverage the latest advancements in SQL Server high availability.
