[syslog-ng] Problem using tags with syslog-ng 3.1

Hi all,
I got a problem to get the "tags" feature working on our syslog-ng 3.1.
I want to collect messages from 3 different files on the
source system and want to separate them again on the central logging
server.
The client configuration looks like this:
------------------------------------------------------------------------
----------------------------
source s_app {
file("/var/log/log1.log");
file("/opt//log/log2.log" tags("log2"));
file("/opt/log/log3.log" tags("log3"));
};
options {
};

destination d_app { tcp("logrelay01.domain.com" port(13074)); };

log {
source(s_app);
destination(d_app);
};
------------------------------------------------------------------------
----------------------------
 
The log relay does nothing than forward the messages to the central
logging server with the following config:
------------------------------------------------------------------------
----------------------------
options {
time_sleep(20);
log_fifo_size(1000);
dns_cache(2000);
dns_cache_expire(87600);
keep_hostname(yes);
};

source s_remote { tcp(ip("0.0.0.0") port(13074)); };
 
destination remote_tcp { tcp("centrallog01.domain.com" port(13074)); };
 
log {
source(s_remote);
destination(remote_tcp);
};
------------------------------------------------------------------------
----------------------------
 
On the central logging server I use filters to separate the logfiles
again:
------------------------------------------------------------------------
----------------------------
@version: 3.0

include "/opt/config/syslogng-inc.conf";
 
options {
time_sleep(20);
dns_cache(2000);
dns_cache_expire(87600);
keep_hostname(yes);
create_dirs(yes);
};

source s_remote { tcp (ip("0.0.0.0") port(13074) keep-alive(yes)); };

============================================
 
This is the confoguration in /opt/config/syslogng-inc.conf
# Filter
filter f_log1 { host("web00(09|10)"); };
filter f_log2 { host("web00(09|10)") and tags("log2"); };
filter f_log3 { host("web00(09|10)") and tags("log3"); };
 
#Configuration for Destinations
destination d_log1 { file("/var/logs/log1/combined.log" perm(0755)
dir_perm(0755)); };
destination d_log2 { file("/var/logs/log2/combined.log" perm(0755)
dir_perm(0755)); };
destination d_log3 { file("/var/logs/log3/combined.log" perm(0755)
dir_perm(0755)); };

# Logfile log1
log {
source(s_remote);
filter(f_log1);
destination(d_log1);
};
 
# Logfile log2
log {
source(s_remote);
filter(f_log2);
destination(d_log2);
};
 
# Logfile log3
log {
source(s_remote);
filter(f_log3);
destination(d_log3);
};
------------------------------------------------------------------------
----------------------------
 
Does anybody have an idea, why it does not work as expected.
 
Thanks for any suggestion and/or idea.
 
Best regards Stefan
