Hello @Subhadip Roy Thank you for contacting us!
From your original post I learn that you want to disable/stop resources not in use for certain time.
You can use Azure CCO dashboard to generate a report and find out idle resources. - https://github.com/Azure/ccodashboard
However for alerting you might need to setup your own custom scripts.
I could also recommend the following blog post from Billy York:
Find Orphaned Azure Resources - with Azure Resource Graph (cloudsma.com)
He has spoken at the last SPARK about Azure Resource Graph.
Hope this helps!
