How can I calculate the life span of the issues?

[Alex Yang]

for example, a bug was created on June 1st, and opened, in progress, resolved at last. It was closed on June 15th. So, the life span of it is about 15 days. 

Our project has many bugs, I want to calculate how much time we used by average to resolve a bug, from its creation to close. 

I checked the gadget, but can't find a proper one. 

e.g. Average age chart, Average number of times in status, Average time in status, etc. 

I am not sure if the charts above can approach that, maybe I can't find the correct way. 

Any help will be much appreciated.

Hi @Alex Yang 

You can try Time in status for Jira Cloud by SaaSJet.  This application will give you the information about time in status and average time in status by each issue.

Also, this add-on gives you data about: assignee time in status, status entrance date, time in status per date, status count and transition count.

Charts will show you the overall picture of the data from your reports. All report is available for export.

Hi @Alex Yang  - Have you tried exercising Resolution Time Report for your use case ? If you were to check built-in Reports in JIRA, under Issue-analysis you will find the Resolution time report. You will be able to input Issue filter (which in this case can have a query to bring only bug issue type), Period and Days Previously. Read on here if you think this Report might help.
