Modbus settings are not read from config?

[vomus]

Hi!
I am collecting some metrics over Modbus and configured agent2 like this

[root@veles zabbix_agent2.conf.d]# cat modbus_safianovo.conf  
Plugins.Modbus.Sessions.Safianovo.Endpoint=tcp://10.161.0.25:502
Plugins.Modbus.Sessions.Safianovo.SlaveID=10
Plugins.Modbus.Sessions.Safianovo.Timeout=10

However, when I refer to Safianovo in my request, it does not extract its parameters:

 [serge@veles ~]$ /usr/sbin/zabbix_agent2 --test modbus.get[tcp://10.161.0.25:502,10,3,122,1,int16,be,0]
modbus.get[tcp://10.161.0.25:502,10,3,122,1,int16,be,0][s|1034]
[serge@veles ~]$ /usr/sbin/zabbix_agent2 --test modbus.get[Safianovo,10,3,122,1,int16,be,0]             
modbus.get[Safianovo,10,3,122,1,int16,be,0]   [m|ZBX_NOTSUPPORTED] [Unsupported endpoint format]

Why is this happening? It seems the config is read into agent2...
