Hello Bouke,
God damn it you are good 
Thank you for your time and useful advice.
I have few questions and feedbacks to your advice now.
Feedback:
1. "What I think you should do is reconfigure your current attribute package being used by a resource kind. Follow this step-by-step:"
Sure.
Question:
Before changing the current attribute (default attributes and all attributes), is there a way to confirm default threshold values for specific metrices on an adapter such as EMC adapater?
Because when I dig into the default attribute for example, I can see that some of the metrices are enabled to be alerted, but the threshold values are all empty.
However, the alerts are being generated on the vops-custom UI. Where can I see those default threshold values for the metrics?
2. "Have fun and good luck with changing your resources using fixed thresholds (why on earth would you do that ). Oh and by the way, from the screenshots I noted your sample interval is set to 1 minute. Please, please, please be aware this adds 5 times more values to your database, not only that - VCOPS needs to process 5 times more metrics to calculate the dynamic thresholds and all other fancy stuff VCOPS does. It might generate a lot of stress, just so you're aware..."
It was only for the testing purpose so that I can get the alert right away. But took your advice and changed it to some bigger time interval.
Additional Question:
As soon as I setup/enable Outbound Alert Setup (Alert Type = Email) on vcops-custom UI and SMTP on vcops-admin UI, will the email alerts start coming to the inbox automatically?
If yes, where will I get the email alerts as I do not see any place in vcops-custom UI and vcops-admin UI to specify the email addresses.
Much appreciated.
BR,
Tom
