Resolution time of each blockers

[PHANI RAJ]

Hi team,

i need to know how many blockers are there per sprint and how many days it took to resolve.

Hi,

Maybe somethinh like that could help you

priority = "1-Blocker / SEV1" and issueFunction in aggregateExpression(solving_time, "timespent.sum()") and Sprint = WantedSprint

 You can check sprint by sprint or (without the sprint condition) export as Excel and make your analysis in Excel.
I don't think it is possible to have what you want by using directly JQL query. (Maybe using API queries?)
