The UDP Format
If UDRs are expected as reply back to the collector from the APL agent, extend the internal format to contain the built-in UDP format.
external my_ext { // field definitions int type : static_size(1); ascii Anum : static_size(8); ascii Bnum : terminated_by(0xA); }; internal UDP_Int : extends_class( "com.digitalroute.udp.agent.UDPPacketUDR" ) { }; in_map UDP_InMap : external( my_ext ), internal( UDP_Int ), target_internal( my_UDP_TI ) { automatic; }; decoder myDecoder : in_map( UDP_InMap );
