The rate at which messages enter the incoming queue is determined by
looking at log entries of the form (system dependent):
postfix/cleanup[<pid>]: <queue-id>: message-id=...

NO. DO NOT DO THIS. This totally destroys the performance you are trying
to measure, and is COMPLETELY unnecessary.

You are measuring the wrong thing. When the rates are unequal and the
queue manager is falling behind you won't see this until long after the
message enters the incoming queue.
The other log entry of interest is:
postfix/qmgr[<pid>]: <queue-id>: from=<...>,
which indicates entry into the active queue, from either incoming or
deferred, to know which, you need state parsed from the logs for messages
not yet logged as "removed" that have been in the active queue before.
What's wrong with just measuing the incoming queue size? It is generally
very near zero, and if not, you probably have a problem.
