What does a probe request consist of?

Question

WiFi

Let's say there is a router that is configured to scan WiFi air, the result of this work will be a file with a record of mac-identifiers.
But, it is interesting to know what other attributes will be caught, in addition to mac? Will there be a list of ssids of previously connected points in the requests?
