I hope you have distinguished the portal as critical and non-critical in terms of portal monitoring. We have amended amended the process of monitoring the non-critical portal when we receive an alarm notification on the server. For the non-critical portals, you can start checking after receiving two or more continuous alarm in the interval of 5mins. Also, you can avoid logging in to portals to check whether the portal is loading or not. Instead please follow the steps mentioned in the document shared.

But, follow the existing steps for the portal which you are marked as critical.
