I wnat to send nginx access log to a remote syslog-ng server. I installed syslog-ng on each side (server-client).


Some log files (messages,syslog,mail.log) are successfully sent to the server from the client, but not the nginx log. Server config:

source s_net {
   tcp(ip( port(1999)
   tls( key_file("/etc/syslog-ng/key.d/privkey.pem")
        peer_verify(optional-untrusted)) ); };

destination d_net_nginx_access { file("/mnt/syslog_storage/HOSTS/$HOST
/nginx.access.log"); };

filter f_nginx_access { program("nginx") };

log { source(s_net); filter(f_nginx_access); destination(d_net_nginx_access); };

Client config:

source s_src {

destination tls_log {
tcp("" port(1999)
tls( ca_dir("/etc/syslog-ng/ca.d")) );};

destination d_nginx_access { file("/var/log/nginx/nginx.access.log"); };

filter f_nginx { program("nginx"); };

log { source(s_src); filter(f_nginx); destination(d_nginx_access); };

# All messages send to a remote site
log { source(s_src); destination(tls_log); };

What am I missing here?

That functionality was once reserved to the commercial variant of nginx, but has since been included in the OS version. You can use the nginx module ngx_http_log_module for that.

Here's a link to the module documentation, explaining the setup and configuration:


access_log path [format [buffer=size [flush=time]] [if=condition]];
access_log path format gzip[=level] [buffer=size] [flush=time] [if=condition];
access_log syslog:server=address[,parameter=value] [format [if=condition]];
access_log off;

access_log logs/access.log combined;
Context:    http, server, location, if in location, limit_except

The 3rd form is the one you want to use:

access_log syslog:server=address[,parameter=value] [format [if=condition]];

Include the IP address of the remote server where Syslog is running.
