Here’s a very basic example of a script to review group membership on Jira Server/DC

By first fetching the groups, and then the users in each group, we take the most efficient path toward only fetching the users who are in a group.

On the other hand, we could also tweak this script to show us users who are NOT in a group, or who are in  X or fewer groups.   That might be interesting, too.

 import com.atlassian.jira.component.ComponentAccessor

def groupManager = ComponentAccessor.getGroupManager()
def groups = groupManager.getAllGroups()
def sb = []
//Define a string buffer to hold the results

sb.add("<br>Group Name, Active User Count, Inactive User Count, Total User Count")
//Add a header to the buffer
groups.each{ group ->

 def activeUsers = 0
 def inactiveUsers = 0
 Each time we iterate over a new group, the count of active/inactive users gets set back to zero
 def groupMembers = groupManager.getUsersInGroup(group)
 //For each group, fetch the members of the group
    
    groupMembers.each{ member ->
    //Process each member of each group
        
    def memberDetails = ComponentAccessor.getUserManager().getUserByName(member.name)
    //We have to fetch the full user object, using the *name* attribute of the group member
        
        if(memberDetails.isActive()){
            activeUsers += 1 
        }else{
            inactiveUsers += 1
        }
    }//Increment the count of 

There’s a simple way to return a list of field configurations and field configuration schemes in Jira DC/Jira Server.  However, in order to find that information you have to know that Jira once referred to these as field layouts. 

Using the FieldLayoutManager class, this script returns a list of field layouts:

 import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.fields.layout.field.FieldLayoutManager

def layoutManager = ComponentAccessor.getFieldLayoutManager()
def fieldLayouts = layoutManager.getEditableFieldLayouts()
def sb = []

fieldLayouts.each{ fieldLayout ->

    sb.add("<br> ${fieldLayout.name}")

}

return sb 

This script returns the field layout schemes, with a simple change of the method:

 import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.fields.layout.field.FieldLayoutManager

def layoutManager = ComponentAccessor.getFieldLayoutManager()
def layoutSchemes = layoutManager.getFieldLayoutSchemes()
def sb = []

layoutSchemes.each{ layoutScheme ->

    sb.add("<br> ${layoutScheme.name}")

}

return sb 

This simple script fetches all projects, then fetches each issue in the project.  For each issue, it counts the number of attachments and adds it to a running tally for that project.

 import com.atlassian.jira.component.ComponentAccessor

def projectManager = ComponentAccessor.getProjectManager()
def projects = projectManager.getProjectObjects()
def issueManager = ComponentAccessor.getIssueManager()

projects.each{ project ->

  def attachmentsTotal = 0
  def issues = ComponentAccessor.getIssueManager().getIssueIdsForProject(project.id)

  issues.each{ issueID ->

    def issue = ComponentAccessor.getIssueManager().getIssueObject(issueID)
    def attachmentManager = ComponentAccessor.getAttachmentManager().getAttachments(issue).size()
    attachmentsTotal += attachmentManager

  }
  log.warn(project.key + " - " + attachmentsTotal)
}
