Hello. Perfect! Problem solved using templates!

You can customize the output using a template() option, e.g.: program("/bin/foobar" template("$ISODATE $HOST $MSGHDR$MSG\n")); But you can include any macro or name-value pair in the template, or even transform the output using template functions. The template language is a pretty powerful part of syslog-ng that allows a lot of customization on how a log message is sent to a peer.

I have found the problem that cause my destination program not work. Indeed I see that the log line received by the destination program are preceeded by the string '<190>'. I can't explain why this strings appear, but after updating the program so that the log line are trimmed of the leading characters, the program has worked as I expected. Could someone explain why the string '<190>' appear? Regards, Rocco

Hello.
Thanks for the answer Sandor Geller. Could you please show me a template program() destination that works following the logic you explained in your answer?
Regards,
Rocco

Hello.
I have written a C program that read the successful POP3 access log lines to my POP3 server. After get one line, it get the time and the POP3 account that logged in. These data are then stored in the account MySQL database.
The program (named 'pop3_access') works fine:
echo "Apr 10 12:00:17 mail1 pop3d: LOGIN, user= xxx@domain.tld<mailto:xxx@domain.tld>, ip=[::ffff:xxx.yyy.zzz.vvv], port=[56196]"|./pop3_access
Infact quering DB, I get:
username pop3_last_access xxx@domain.tld<mailto:xxx@domain.tld> 2018-04-10 12:00:17
I have configured syslog:
filter f_pop3_access { facility(local7) and match ('LOGIN,'); }; destination d_pop3_last_access { program("/usr/local/bin/pop3_access
/dev/null" ); }; log { source(src); filter(f_pop3_access); destination(d_pop3_last_access); };
But no rows are inserted in the database..
From log of destination program 'pop3_access' I see the it remains in a while loop waiting for an 'EOF' that never arrives:
while (fgets(line, MAXSTR, stdin)) { if (sscanf(line, "%s %d %s %s %s %s %s %s %s", mese, &giorno, ora, s, proto, comando, u, ip, porta) != 9){ syslog (LOG_NOTICE, "Errore scanf"); exit(-1); } }
How I have to do so that my program succeed in taking the syslog row correctly, and then returns after process the data as expected?
Regards,
Rocco Scappatura
