Do you want to improve your support operation then you know that numbers will tell you the tale.  How long does it take to pick up an issue, what is the average resolution time.  Atlassian is providing a great product to manage the complete support cycles, but at a price.   This blog is about an alternative which is based on the Script Runner for JIRA which allows you to create calculated fields through a simple groovy script.

  • Access the scripted fields section of the add-on
  • Edit the newly created field and add following script to calculate the number of days between the creation and the resolution
def createDate = issue.getCreated();
def resolutionDate = issue.getResolutionDate();
if (resolutionDate == null) {
   return null;
return resolutionDate - createDate;
  • make sure that the template is set to a number
  • Save the configuration and you’re done.
