Hi Community.
I am going to analyze the Sprint on the following aspects:
1) How many tickets have been planned (the commitment) ?
2) How much time the team spent on the initially planned tickets ?
3) How many BUGS and urgent Enhancements have been added to Sprint after the sprint start ?
4) How much time the team spent on the added tickets ?
I could not filter out the tickets from point 3) using regular JQL. Tried to find anything useful in Marketplace for free
but it was a useless work
Could you please help me to come up with a better approach on this report ? Any useful plugin for Jira Cloud that does the job ? Preferably FREE ones 
Thanks,
Arthur
