Important: Should the system go down, it's important to ensure all services are running correctly once it is back up. SQL Server may have stopped, ensure it has restarted on the SQL Sentry database server. Different components may come back online in an unexpected order. You should restart all SQL Sentry monitoring services to confirm that there are good connections and everything is running fully.
