Non-existing servers in audit whitelist

If a server has been included in the dbo.audit_whitelist 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 excluded from the audit functionality, use:

select a.*
from dbo.audit_whitelist a
left join dbo.servers s on s.server_name = a.server_name and s.discovered = 1
where s.server_name is null
and a.server_name is not null

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.
