how to track usage for our country codes utility efficiently?

hey guys, we're trying to get a better handle on user engagement for our country codes directory web utility and it's been a bit of a head-scratcher. what are some best practices or tools you all use for really granular usage data on simple web utilities like ours? we'd love to track things like which codes are looked up most, how many times someone copies a code, that kinda stuff. here's a dummy console output showing what i mean:

// Desired Tracking Output
{ event: 'code_lookup', country: 'Germany', code: '+49', iso: 'DEU' }
{ event: 'code_copied', country: 'United States', code: '+1' }
{ event: 'page_view', path: '/country/france', user_agent: 'Mozilla/5.0...' }

help a brother out please...
