Always On Availability Groups

This dashboard provides an at-a-glance overview of Always On Availability Groups (AGs) across the selected instances. Use it to verify AG health, replica roles, and synchronization status, and to quickly locate groups that need attention.

Availability Groups table

• Availability Group: AG name (click to open the AG detail dashboard).
• Primary Replica: the current primary replica host for the AG.
• Secondary Replicas: comma-separated list of configured secondary replicas.
• Total Nodes: number of replicas configured in the AG.
• Online Nodes: replicas currently online and reachable.
• N. Databases: number of databases protected by the AG.
• Synchronization Health: overall sync state (Healthy, Not Healthy) based on replica synchronization and failover readiness.
• Listener DNS Name: cluster listener DNS name, if configured.
• Listener IP: listener IP address or addresses.

Usage

• Click an AG name to view the detail dashboard for per-replica metrics, database synchronization progress, failover readiness.
• Filter or sort the table to find AGs with offline nodes, unsynchronized databases, or other anomalies that require investigation.
