Non-existing servers in extended audit include

If a server has been included in the dbo.audit_extended_include table, but does not exist anymore, this alert will be thrown.

To query the Performance Store database for servers that do not exist, but are marked to be included in the extended audit functionality, use:

select a.*
from dbo.audit_extended_include a
left join dbo.servers s on s.server_name = a.server_name
where s.server_name is null
and a.server_name is not null
and a.server_name not like '%[%]%'

The alert will be visible on the Latest stats dashboard.

To exclude specific servers from this alert, see how to use the dbo.team_alert_exclude table in Alerting.
