The partials tab of your SpaceFarmer dashboard helps you monitor the partials you submit to the pool. There are six columns:
Status shows if the partial you submitted is valid. It takes 2 minutes before your partial is validated. This is to make sure the signage point is not reverted.
Note that you can filter the partials tab to only show the invalid partials you submitted. This can be of great help in debugging and it's there to help you become a better farmer. To understand partial quality better see the list of pool partial quality. An aggregated overview of partials submitted per plot and per harvester can be found in the plots tab.
