Deliver
If the routing class is “Deliver” or “FDA”, MM will look for routing rules that specify a routing class of
“Deliver”. Each path listed in the routing rule will be attempted in turn, until either a successful or
permanent failure response is received. Statistics are recorded for each path that delivery is attempted
on, with the detail field being populated by the outbound path's statistics category. The term “attempt”
includes any retries that are configured for the path. The outcome of a delivery attempt is one of:
Statistic
Description
MSG_PATH_DELIVER_RETRY_SUCCESS
Delivery initially fails, but is successful on the
first or subsequent retries
MSG_PATH_DELIVER_TEMP_ERR
Initial delivery and all retries return a
temporary error
MSG_PATH_DELIVER_PERM_ERR
Initial delivery or one of the retries returns a
permanent error (so there are no further
retries)
MSG_PATH_DELIVER_TIMEOUT
Initial delivery or one of the retries times out
(so there are no further retries)
MSG_PATH_DELIVER_ATTEMPT
For every delivery attempt on a path listed in
a Deliver routing rule, MM will increment this
statistic, with the outbound path's statistics
category in the detail field
MSG_PATH_DELIVER_bucket_COUNT
For every successful delivery attempt on a
path listed in a Deliver routing rule, MM will
increment this statistic, where the bucket is
determined by the response time from the
MSC with the outbound path's statistics
category in the detail field.
Where bucket can be:
MSG_PATH_DELIVER_bucket_TIME
Bucket
Response Time
RT1
<= 1 second
RT2
> 1 second
<= 5 seconds
RT3
> 5 seconds
<= 10 seconds
RTX
> 10 seconds
For every successful delivery attempt on a
path listed in a Deliver routing rule, MM will
add the response time to this statistic, with
the outbound path's statistics category in the
detail field (where bucket is determined as
above).
Note: The number of attempts that produce a successful delivery with no retries required can be derived
by subtracting the other outcomes from MSG_PATH_DELIVER_ATTEMPT.
