How difficult is to report JIRA Worklog? There are several plugins and a couple of API call for free but none of them so far can report on a basic metric: How many hours each member of the team worked per ticket in a particular date or date range.
I do not like to go to the database directly but rather I prefer API endpoints, however while I wait for a free solution to this problem I guess the most effective way to pull such information is unfortunately to query the jira database directly.
Below is an example to get the hours per team member and ticket for yesterday. You could tweak this example to get all kind of information about worklog.
If you want to include custom fields like 'Team' see below:
