Work-search log: how detailed does it need to be? (update)

I am keeping a spreadsheet of applications, but I worry it is not what the agency expects. It has been weighing on me all week. I also did a résumé workshop at the library. What do you record?

Screenshots of the submitted application are handy backup when a posting disappears.

I was asked for my log once, after six months. Having it in a spreadsheet made it painless.
