monitoring the effectiveness of smtpd processes

[juan smitt]

Hi,


How can one directly monitor the effectiveness of the increased number
of Postfix SMTP server processes?
(https://www.postfix.org/STRESS_README.html)

Is it true that this scales up dynamically until the limit, which
means I can monitor it indirectly by counting the number of processes
(and also checking the delay in the mail log)?

Thanks,
