At one point in time (when you run a query to do this) you can see how many records are in your (new) "users_log" table that have been updated within a set number of seconds/minutes. That's all you can do I believe.
@JIBONSARKERSep 24.2022 — #A total of 5.03 billion people around the world use the internet today – equivalent to 63.1 percent of the world’s total population.
@ginerjmSep 25.2022 — #Yes it will but as I surmised, it will show the users that hit the site. He just has to figure out the credible ones for whatever purpose he wants to collect this data.
