[syslog-ng] why this messages from syslog?

[Maurizio B]

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
