Re: [syslog-ng] Problem sending logs to central log server..

19 Sep 2011


      Dont forget to leave the mailing list on the list of recips :-)

Anyway, its still commented out in your log {} block. If the log block 
has no source, it wont log anything.
log {
#    source(src_eventdb);
     filter(f_at_least_warn);
#     filter(f_syslog);
     destination(d_eventdb);
};

Hi Patrick, thanks for your reply, yes you right sorry I did the copy 
and paste before I uncomented some lines since Im testing here and 
there..
this is how I have it now.. the last part:
#syslog-ng2mysql destinations
source src_eventdb {
    unix-stream("/dev/log");
    udp(ip(0.0.0.0) port(514));
};
destination d_eventdb {
    pipe(
        "/usr/local/icinga/var/rw/syslog-ng.pipe",
template("$HOST\t$SOURCEIP\t$PRI\t$YEAR-$MONTH-$DAY\t$HOUR:$MIN:$SEC\t$PROGRAM\t$MSG\n")
        template_escape(no)
    );
};
filter f_at_least_warn {
#    level(warn..emerg);
#     level(notice..emerg);
     level(info, notice, warn, crit, err, debug);
};
log {
#    source(src_eventdb);
    filter(f_at_least_warn);
#     filter(f_syslog);
    destination(d_eventdb);
};
#log {
#        source(src_eventdb);
#        filter(f_auth);
#        destination(d_eventdb);
#};

In your server config, the only listener you have on udp port 514
    is defined in src_eventdb, and all src_eventdb entries are
    commented out.

    Subject: [syslog-ng] Problem sending logs to central log server..
...
Hello, I'm trying to sent all my logs from one openbsd server
    with syslog-ng to a linux ubuntu central log server also with
    syslog-ng of course but only the syslog-ng logs are been logged..
    also when I do a "logger test" for example it gets log locally
    but not remotely to the log server...
    here are my configs:
for the log server is basically the defaul of ubuntu with my
    addtions at the end.. you will see
    some commented is me trying to fix this issue.
