[syslog-ng] why this messages from syslog?

why I get this messages from syslog-ng 2.0rc1? Log statistics; processed='source(s_local)=19', processed='source(s_remote)=0', processed='destination(dsl_console)=0', processed='destination(dsl_maillog)=0', processed='destination(ds_emerg)=0', processed='destination(ds_alert)=0', processed='destination(df_uucp)=0', processed='destination(ds_err)=0', processed='destination(dfs_err)=0', processed='destination(dsl_messages)=16', processed='destination(dfs_crit)=0', is it a misconfiguration? thanks in advance
