Can't find Name field to report Time Spent per person on an Issue

[Alistair Hindmarsh]

I'm trying to create a filter that shows the Time spent per Person on an Issue. I've created one so it shows the Issue and the Time spent plus the Assignee and the Reporter. However, the Time Spent is for the entire issue. I need to see who has logged time against the issue from the Work Log and how much time that has been but I can't find the field from the MORE+ drop down list. 
Does anyone know what the field is called or how I find it?
Much appreciated

Hi @Alistair Hindmarsh 

Welcome to the community !!

You can use Jira Rest API's to pull the author time spent data and build your own custom solution. Or if you would be interested in a mktplace app , take a look at

Worklogs Time Tracking & Timesheets

You can easily view time entries for multiple issues day wise grouped by authors in a single view. The app allows to filter/Categorize/Group By your worklogs data and a timesheet view too to track individual time spent. And what's more it can be added as a dashboard gadget. 

Below are some of the reports extracted from the app.

Sadly we don't have the budget to buy another application. I was hoping to find something within Jira itself without having to build a custom solution. I'm puzzled that you can have a task in Jira but in a filter or report you can't see who worked on it and what time they spent on it, you can only see who it was assigned to and the total time spent. I can see why your app had to be created.

Hi @Alistair Hindmarsh , The app is free

Maybe my mistake, the link said "Try it for free" implying the trial was free but there would be payment afterwards - is that not the case then?
