[SR-Users] kamctl get number of subscribers

Hi all I'm trying to get the number of registered subscribers in a kamailio 3.0.4 setup. I'm trying to use usrloc's exported function "ul_get_num_users" but I get a 500 error: kamctl fifo ul_get_num_users 500 command 'ul_get_num_users' not available Using get_statistics I get: test3:~# kamctl fifo get_statistics usrloc: usrloc:registered_users = 2 usrloc:location-users = 2 usrloc:location-contacts = 2 usrloc:location-expires = 0 Trying to query for a specific stat, seems like I do not use the correct syntax: test3:~# kamctl fifo get_statistics usrloc:registered_users 404 Statistics Not Found Anyone could help me with the correct syntax for the function and fifo? thanks
