We moved to VSTS recently, I wonder if there any Widget or a query to get the hours logged by an individual for each day in the sprint.
Stop micromanaging and focusing on low value metrics.
Additional: Attempting to use how many hours each person worked as a tool for issue analysis is dysfunctional. (It is also a metric that can be easily gamed.) In order to investigate and address any possible issues, the team needs to have a candid discussion during the Sprint Retrospective (Scrum) or similar agile principled reflection.
