Pendo Data Mappings

hello everyone, I've been poking around for a while trying to understand how to interpret the exports generaded by pendo, I have no issues generating all kind of files (allevents, accounts, visitors, etc) but mapping what the documentations says is getting kind of hard with what I'm seeing on the files, i.e Trying to figure out how to identify a page view, at this point what I've found is that I need to filter the eventType load and that's my page views, also, I'm seeing on the reports that there are some metrics such as time spent on site, where are this metrics being exported? haven't been able to find it on any files that were generated...if you can point me on the right direction would be great!
