@hazard74 SHOW FULL PROCESSLIST or SHOW PROCESSLIST has the thread ID displayed in the first column as a reference for you. When you review a General Log and you see queries listed in order received, this is the glue that helps hold the details together for analysis.

That is the process id as assigned by the OS. See the

It's a thread_id as per https://dev.mysql.com/doc/refman/8.0/en/error-log-format.html :
This log writer produces the traditional error log output. It writes messages using this format:
timestamp thread_id [severity] [err_code] [subsystem] message
The [ and ] square bracket characters are literal characters in the message format. They do not indicate that fields are optional.
