Statistics
IPSMGWFetchRoutingInfoCassandra statistics are tracked by the sentinel.ipsmgw SBB
and can be found under the following parameter set in REM:
SLEE-Usage → sentinel.ipsmgw service → sentinel.ipsmgw SBB → feature → IPSMGWFetchRoutingInfoCassandra
or with rhino-stats:
"SLEE-Usage.Services.ServiceID[name=sentinel.ipsmgw,vendor=OpenCloud,version=2.5.1].SbbID[name=sentinel.ipsmgw,vendor=OpenCloud,version=2.5.1].feature.IPSMGWFetchRoutingInfoCassandra"
| Name | Description |
|---|---|
FetchRoutingInfoSuccess |
Incremented when a matching record is returned from Cassandra |
FetchRoutingInfoFailure |
Incremented when a matching record is not returned from Cassandra |
Configuration
The feature uses the IPSMGWRoutingInfoCassandraConfigProfileTable profile to configure whether tracing is enabled for Cassandra queries.
Behaviour
The feature is triggered on MAP MT Forward Short Message (MT-FSM) requests. The IMSI in the MT-FSM is used as the primary key when querying Cassandra. The contents of the query are written into session state, and used to facilitate delivery of the SMS.
In the success case, the Store Routing Info Cassandra feature will have written the relevant data to Cassandra using the schema detailed here, and so the query will find a row. The row contents include the Circuit Switched Routing information for SMS (i.e. the SRI request and response). If a row is not found, an UnidentifiedSubscriber error is returned to the SMSC.
