Extended Events Login audit - Reduce login noise

We are looking for the optimal sql login audit solution, with usable filtering.

Thus far we have looked into Server Audits and profiler but have concluded that extended eventslook most promising, unless anyone can show us otherwise.

Question is, is there any good way to filter unnecessary login events? e.g. when I connect using SSMS, immediatly about 10 login events are added and continue to pile up if I leave SSMS connected to a instance. Why is that?

This is our current implementation:

USE master;GO-- Create the Event SessionIF EXISTS    (        SELECT                  *            FROM  sys.server_event_sessions            WHERE name = 'ServerLoginAudit'    )    DROP EVENT SESSION ServerLoginAudit ON SERVER;GOEXECUTE xp_create_subdir 'D:\audits\Sessions';GOCREATE EVENT SESSION ServerLoginAudit    ON SERVER    ADD EVENT sqlserver.login        (SET             collect_database_name = (1)           , collect_options_text = (1)         ACTION             (                 sqlserver.sql_text               , sqlserver.nt_username               , sqlserver.server_principal_name               , sqlserver.client_hostname               , package0.collect_system_time               , package0.event_sequence               , sqlserver.database_id               , sqlserver.database_name               , sqlserver.username               , sqlserver.session_nt_username               , sqlserver.client_app_name               , sqlserver.session_id               , sqlserver.context_info               , sqlserver.client_connection_id             )        )    ADD TARGET package0.event_file        (SET filename = N'D:\audits\Sessions\ServerLoginAudit.xel', max_file_size = (20), max_rollover_files = (2))    WITH        (            STARTUP_STATE = OFF          , TRACK_CAUSALITY = ON        );/* start the session */ALTER EVENT SESSION ServerLoginAudit ON SERVER STATE = START;GO
