the @confgen line only registers a source driver named s_nginx_modsec_log that you'll have to use in order to expand this in your configuration file.

@confgen is assumed to be used at the top level, whereas the driver being declared as a normal source statement.


@module confgen context(source) name(s_nginx_modsec_log) exec("/etc/syslog-ng/scripts/confgen-modsec-skeleton.sh")

log {
    source { s_nginx_modsec_log(); };
    destination(d_collector);
};

Your source name uses the conventions of a source drive (the s_ prefix), so you probably assumed that it is declaring a source, but it isn't. It defines a source driver.

Hi guys!


1) I have my 'confgen' script that prints the below file() entries. (p.s: these files has content.)

# /etc/syslog-ng/scripts/confgen-modsec-skeleton.sh
file("/opt/nginx/logs/waf/www.cocada.com" program_override("ng_modsec") flags(no-parse));
file("/opt/nginx/logs/waf/www.caipirinha.com" program_override("ng_modsec") flags(no-parse));
# 

2) My config set:

# cat /etc/syslog-ng/conf.d/nginx_modsec.conf 
options {
    threaded(yes);
    flush_lines(0);
    use-dns(no);
    normalize-hostnames(yes);
    keep-hostname(yes);
};

destination d_collector {
    tcp("192.168.1.248" port(514)  keep-alive(on)  );
};

log {
@module confgen context(source) name(s_nginx_modsec_log) exec("/etc/syslog-ng/scripts/confgen-modsec-skeleton.sh")
    destination(d_collector);
};

# 

Conclusion: The syslog-ng doesn't call the script at any time.

# strace -fff /usr/sbin/syslog-ng -dvte 2>&1 | grep "confgen-modsec"

p.s: I have 'confgen' support.

# syslog-ng --version | grep confgen
Available-Modules: syslogformat,kvformat,afamqp,sdjournal,system-source,afuser,json-plugin,dbparser,affile,afsocket,linux-kmsg-format,afmongodb,mod-python,confgen,csvparser,pseudofile,afsql,afprog,afstomp,cryptofuncs,graphite,basicfuncs

I appreciate any help.

Best,
