Firewall Aliases – Function of Statistics Option

[wiring8228]

What does the 'Statistics' option, which has the description 'Maintain a set of counters for each table entry', actually do? Which counters is it referencing?

I can't see any change in Diagnostics > Aliases when I activate this option for an alias.
The following is the only documentation I could find about it: https://docs.opnsense.org/manual/diagnostics_firewall.html#aliases

It only counts pass matches... most of the time. I don't think I ever characterized it fully, and I've forgotten the details. How are the aliases you are testing applied?

The counter increases only for non Port based aliases.

I'm using a GeoIP alias that gets used in firewall rules to only allow traffic to some countries (whitelist principle).
