What kind of change does this PR introduce?
This PR adds two new metrics,
gotrue_email_send_operations_counter_totalandgotrue_email_send_errors_counter_total, for tracking email send operations and errors respectively. The purpose of these metrics is to track email delivery independently of the various API handlers that may send email within Auth.What is the current behavior?
Users who want to track email sending operations in Auth must use indirect metrics like HTTP status codes to determine whether an email was successfully sent.
What is the new behavior?
The
gotrue_email_send_operations_counter_totalcounter will increment each time Auth attempts to send an email after performing validation and checking rate limits. Thegotrue_email_send_errors_counter_totalcounter will increment each time an email send attempt fails.
