In this post, I am sharing one T-SQL script to monitor the status and health of AlwaysOn Availability Groups of SQL Server.

You can run this script in any primary server and get the information like Group name, Replica server name, Role description, Synchronization state.

DECLARE @DRName varchar(30) 
SET @DRName = @@SERVERNAME 
select 
	n.group_name
	,n.replica_server_name
	,n.node_name,rs.role_desc
	,db_name(drs.database_id) as database_name
	,drs.synchronization_state_desc
	,drs.synchronization_health_desc 
from sys.dm_hadr_availability_replica_cluster_nodes n 
join sys.dm_hadr_availability_replica_cluster_states cs 
	on n.replica_server_name = cs.replica_server_name 
join sys.dm_hadr_availability_replica_states rs  
	on rs.replica_id = cs.replica_id 
join sys.dm_hadr_database_replica_states drs 
	on rs.replica_id=drs.replica_id 
where n.replica_server_name <> @DRName
