How to monitor team progress without team logging time in stories?

In our company the devs don't login time in stories, we do estimation in days and hours.
At the time of PI planning, we input PI estimation in Jira, and before starting sprints we groom stories to estimate original time with more information. We don't login time in stories, because according to developers its micromanaging and it takes a lot of effort to login time in Jira and Timesheets both. So, we ask them to only login time in Timesheet only now.
But this has created a gap, as we are not able to assess team's performance as we have spills happening and we donno if the dev spent as much time as was required in the story at the time of original estimate.
So my question is, how can we asses our team's performance and plan our deliverables without getting the team to login time in stories?
