How to get Duration of Running Instances without using Query Builder

Hello Experts,

I have a requirement to find out and setup an alert, if the instances on the platform are running for more than 2 hours. Lets say an instances started running on 21st June at 12:00 am, so at 2:00 am , an alert via email or something should be created with the instance details.

Using query builder I was able to find out these details manually, but this has to be automated so that it is monitored continuously. Kindly suggest. Thank you.
