SMSD retry backoff on full dispatch failure (specification)
Introduction
When all dispatchers fail to dispatch an SMS, smsd will retry at the next queue read (which implies a 30 second delay, using default values). A total dispatch failure is a CRITICAL level error, and the loghandler will notify the NAV admin via e-mail.
A long-lasting error state will result in a lot of e-mail spam for the administrator. This should be mitigated by introducing a backoff mechanism for retries.
Requirements
- For each completely failed dispatch attempt, the retry delay will increase by a factor X.
- Factor X must be configurable in
smsd.conf - Once Y repeated dispatch attempts have been unsuccessful, smsd will give up and ignore the remaining messages.
- When smsd gives up, this should be logged as a CRITICAL error, and details of the ignored messages should be logged along with it (so the admin can see what they just missed).
- The value of Y must be configurable in
smsd.conf
