SQL Server AlwaysOn availability groups provide database clusters that streamline automatic failovers and disaster recovery, but can be complex to understand and troubleshoot. Datadog's AlwaysOn view in Database Monitoring provides high-level overviews of these groups with color-coded visualizations, historical data for each node, and out-of-the-box timeseries graphs for log, redo, and secondary lag time metrics. This enables users to quickly assess database health, prepare for failovers, analyze historical metrics to investigate cluster bottlenecks and failures, and set up monitors to alert them when nodes fall out of sync or exhibit unusual behavior.
