   - Diameter clients:\n\
\n\
   entity:                                  Target diameter entity (comma-separated '<address>:<port>' format).\n\
                                            For example: 10.20.30.40:3868,10.20.30.41:3868. If missing, no entity will be enabled.\n\
   entityServerSessions:                    Diameter entity server sessions (0: diameter entity disabled). Default value of 1.\n\
   cer:                                     User defined CER path file to be encoded to establish diameter connections.\n\
                                            If missing, will be harcoded.\n\
   dwr:                                     User defined DWR path file to be encoded for diameter protocol keep alive.\n\
                                            If missing, will be harcoded.\n\
   tcpConnectDelay:                         Milliseconds to wait TCP connect to any server. If missing, default value of 200 will\n\
                                            be assigned\n\
   ceaTimeout:                              Milliseconds to wait CEA from diameter server. If missing, default value of 'answersTimeout'\n\
                                            will be assigned.\n\
   watchdogPeriod:                          Milliseconds for watchdog timer (Tw) for diameter keep-alive procedure. If missing, default\n\
                                            value of 30000 will be assigned.\n\
   balance:                                 Balance over entity servers instead of doing standard behaviour (first primary, secondary\n\
                                            if fails, etc.). Default value 'no'.\n\
   sessionBasedModelsClientSocketSelection: By default, round-robin will be applied for IEC model (SMS/MMS), and Session-Id Low Part\n\
                                            will be analyzed for ECUR/SCUR model (data, voice and content). You could change ECUR/SCUR\n\
                                            analysis behaviour providing 'SessionIdHighPart', 'SessionIdOptionalPart' (atoi applied;\n\
                                            usually subscriber id data, i.e. MSISDN or IMSI) and 'RoundRobin' (also 'SessionIdLowPart').\n\
\n\
\n\
   - Diameter servers:\n\
\n\
   diameterServer:                          Diameter own server address in '<address>:<port>' format. For example: 10.20.30.40:3868.\n\
                                            If missing, no local server will be enabled.\n\
   diameterServerSessions:                  Diameter own server available connections (0: diameter server disabled). Default value of 1.\n\
                                            Negative value implies no limit accepting incoming connections.\n\
   cea:                                     User defined CEA path file to be encoded to answer client CERs.\n\
                                            If missing, will be harcoded.\n\
   allowedInactivityTime:                   Milliseconds for the maximum allowed inactivity time on server sessions born over the\n\
                                            local server before being reset. If missing, default value of 90000 will be assigned.\n\
\n\
\n\
   - General:\n\
\n\
   answersTimeout:                          Milliseconds to wait pending application answers from diameter peers. If missing,\n\
                                            default value of 10000 will be assigned.\n\
   retries:                                 Expired responses will cause a number of request retransmissions. Disabled by default (0 retries).\n\
   log:                                     Process log file (operations result, traffic log, etc.). By default '<originHost>.launcher.log'.\n\
                                            Empty string or \"null\" name, to disable. Warning: there is no rotation for log files\n\
                                            (use logrotate or whatever you consider).\n\
   splitLog:                                Splits log file (appends to log filename, extensions with the type of event: see help on\n\
                                            startup information-level traces). No log files for code/decode and load operations are created.\n\
                                            Default value 'no'.\n\
   detailedLog:                             Insert detailed information at log files (timestamps, communication resources, etc.). Useful\n\
                                            to analyze the messages flow along the sockets (specially on 'balance' mode). Default 'no'.\n\
   dumpLog:                                 Write to disk every incoming/outcoming message named as:\n\
                                               '<unix ms timestamp>.<originHost>.<hop by hop>.<end to end>.<message code>.<request|answer>.<type of event>.xml'\n\
                                            Default value 'no'.\n\
   burstLog:                                Burst operations log file. By default '<originHost>.launcher.burst'. Empty string or \"null\" name, to disable.\n\
                                            Warning: there is no rotation for log files (use logrotate or whatever). Output: dot (.) for each\n\
                                            burst message sent/pushed, cross (x) for popped ones, and order number when multiple of 1% of burst\n\
                                            list size, plus OTA requests when changed.\n\
