Work-search log: how detailed does it need to be? - 5 months and counting

I am keeping a spreadsheet of applications, but I worry it is not what the agency expects. Any experience at all would help. My state says to keep records for a year. 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.
