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. For definitions of pool partials, see this page. Any partial (valid or invalid) that is of a high enough quality to be eligible block, will be displayed with a trophy icon.
In the plot key column you can find the plot file that generated your blockwinning partial.
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. An aggregated overview of partials submitted per harvester can be found in the harvesters tab.
