Description
I am running syslog-ng
inside a Docker container (based from debian:wheezy
) with the following configuration:
@version: 3.5 options { flush-lines(1); }; source s_local { internal(); unix-stream("/dev/log"); }; source s_loopback { tcp(ip(127.0.0.1) max-connections(5000)); udp (); }; destination d_local { file("/var/log/${YEAR}-${MONTH}-${DAY}/messages" template("${YEAR}-${MONTH}-${DAY}T${HOUR}:${MIN}:${SEC}${TZ} ${HOST} [${LEVEL}] ${PROGRAM} ${MSG}\n") template_escape(no)); }; log { source(s_local); destination(d_local); }; log { source(s_loopback); destination(d_local); };
I have the following in my nginx
configuration:
daemon off; http { server { access_log syslog:server=unix:/dev/log; error_log stderr warn; } }
Inside the container, I start syslog-ng
which creates /dev/log
:
# ls -al /dev/log srw-rw-rw- 1 root root 0 Jun 27 16:08 /dev/log
Then (also inside the container) I start nginx
. When I hit nginx
(with curl
), I don't get any access log messages in /var/log/.../messages
and get errors like the following on stderr
:
... *25 send() to syslog failed while logging request, client: 10.68.69.1, server: , request: "GET / HTTP/1.1", ...
Note the blank value for server:
. If I change the nginx
configuration to the following, everything works as expected (I get access and error messages in /var/log/.../messages
, and the previous send()
error log warnings go away):
daemon off; http { server { access_log syslog:server=localhost; error_log syslog:server=localhost warn; } }
All my nginx
packages are from Debian's wheezy branch:
# dpkg -l nginx\* Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend |/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad) ||/ Name Version Architecture Description +++-==================================-======================-======================-========================================================================= un nginx <none> <none> (no description available) ii nginx-common 1.9.1-1 all small, powerful, scalable web/proxy server - common files un nginx-doc <none> <none> (no description available) un nginx-extras <none> <none> (no description available) ii nginx-full 1.9.1-1 amd64 nginx web/proxy server (standard version) un nginx-light <none> <none> (no description available)
nginx uses datagrams when writing messages to log;
you have configured unix-stream("/dev/log"), what
is wrong. Use "unix-dgram" source to receive
datagrams.
