Viewing Run History
If you want check the last time YumYum ran your feed, you can have a look at its 'run history'.
To view the history log, click on the name of your feed in the
Feeds page of the Control Panel. You should then be able to view the last 10 times the feed has been run. It'll tell you both the date/time of last run and how many items were saved as part of that run. This may be helpful if you need to troubleshoot your feed not working correctly.
