There isn't a way to monitor the active sessions generated by SOAP or REST via a SDM command (as it exists for the webengine process, via pdm_webstat -D) or via GUI.
The way to verify how many sessions are currently active is by checking the sda connection messages from the stdlogs:
1. Session created:
servername sda 6192 SIGNIFICANT sda.cpp 2387 Web Services session created 1496143980; user(acesso_soap_rest); IP(10.122.15.67); session count 7
2. Session Ended:
servername sda 6192 SIGNIFICANT sda.cpp 2387 Web Services session ended 2107993368; user(cavizuser); IP(10.146.16.39); session count 76
3. Session expired:
servername sda 6860 SIGNIFICANT sda.cpp 2387 Web Services session found to be expired 262339433; user(cavizuser); IP(10.146.16.39); session count 5
In these messages you can get the user and the IP address from which the connection came from, as well as the session count:
- session count 5
Thus, currently the only way to have some validation done in this area is by checking the stdlogs.
