I would suggest to have visibility for the idle/unused VMs on Azure Portal
Currently, there is no way on the portal where we can identify VMs which has been idle/unused for certain span of time. It is important feature for Azure resource cleanup activity across all subscriptions.
Thanks for the valid suggestion. Your feedback is now open for the user community to upvote which allows us to effectively prioritize your request against our existing feature backlog and also gives us insight into the potential impact of implementing the suggested feature.
