No choice, GA is giving me more and more warnings about the incoming GA4 migration.

Tasks:

• Build an exhaustive list of projects actually exporting to GA4.
• Find how to send GA4 events from my bash scripts.

Taking a reverse approach to that, the Stats Pages I look daily are:

• The Randall Camera Access stats. Data comes from wazz.js.
• ⇒ This seems like a good contender to learn the “official” JS API.
• The Train Activation stats generated by Conductor.
• This uses ad-hoc URL pings.
• And also uses bash-based wget pings.
• The Servers Ping stats.  This uses bash-based wget pings.
• ⇒ This seems like the best candidate to look for a wget alternative.
• The Inkblot Access stats. This uses the official Flutter library.

• Universal Analytics (UA) is the old one.
• Setup Assistant: https://support.google.com/analytics/answer/9744165
• Account Structure: https://support.google.com/analytics/answer/9679158
• UA structure: Account ⇒ N * Properties (e.g. website) ⇒ M * Views.
• The Property number starts with UA-
• GA4 Structure: Account ⇒ N * Properties (e.g. website) ⇒ Data Streams.
• The property number is a long number.
• Looks like GA4 numbers have already been created for each one.
• Events are changing: https://support.google.com/analytics/answer/11091422
• UA events have events category > event action > event label.
• GA4 events are firebase events: event name + event parameters.
• UA event action becomes the new GA4 event name
• UA event category becomes a GA4 event custom parameter
• UA event label becomes a GA4 event custom parameter
