Overview
In the GUI, in Statistics \ Outside Traffic \ Application AO you can see the details of messages received by the platform submitted by an ESME. One of the counters is "Success Messages" and you would like to know what exactly is tracked by this counter. Does it count only messages accepted (command_status=0) by the SMSC or does it also include messages received by the SMSC that could not be delivered?
Information
The counters are uniquely related to AO messages (Submit-sm) received by the applications. When you see "Successful Message", this indicates the AO message (submit-sm) was successfully submitted to the SMSC (submit-sm-respOK). There is nothing related to the final delivery of the message to the end subscriber in this graph. The statistics of MT-fwd-sm can be found at /Statistics/OutgoingTraffic/TotalMT. However, these will be generic measurements, for the entire MT traffic of the platform.
The STV cannot track the entire processing of the message, from submission to final delivery, passing through queuing and reattempts. This is a much more complex task and is the role of the Logging system. You can check if a specific message (or messages from a specific origin) are successfully delivered or not by querying the Logs, either using the LGV ('Logging' tab in the main GUI) or using the CCI ('Events' tab in the CCI GUI), or by using MySQL directly.
