<?xml version="1.0"?> <!-- Copyright (C) Nginx, Inc. --> <!DOCTYPE article SYSTEM "../../../dtd/article.dtd"> <article name="Logging to syslog" link="/en/docs/syslog.html" lang="en" rev="2"> <section> <para> The <link doc="ngx_core_module.xml" id="error_log"/> and <link doc="http/ngx_http_log_module.xml" id="access_log"/> directives support logging to syslog. The following parameters configure logging to syslog: <list type="tag"> <tag-name><literal>server=</literal><value>address</value></tag-name> <tag-desc> Defines the address of a syslog server. The address can be specified as a domain name, IP address, or a UNIX-domain socket path (specified after the “<literal>unix:</literal>” prefix). With a domain name or IP address, the UDP port can be specified. If port is not specified, the port 514 is used. If a domain name resolves to several IP addresses, the first resolved address is used. </tag-desc> <tag-name><literal>facility=</literal><value>string</value></tag-name> <tag-desc> Sets facility of syslog messages, as defined in <link url="http://tools.ietf.org/html/rfc3164#section-4.1.1">RFC 3164</link>. Facility can be one of “<literal>kern</literal>”, “<literal>user</literal>”, “<literal>mail</literal>”, “<literal>daemon</literal>”, “<literal>auth</literal>”, “<literal>intern</literal>”, “<literal>lpr</literal>”, “<literal>news</literal>”, “<literal>uucp</literal>”, “<literal>clock</literal>”, “<literal>authpriv</literal>”, “<literal>ftp</literal>”, “<literal>ntp</literal>”, “<literal>audit</literal>”, “<literal>alert</literal>”, “<literal>cron</literal>”, “<literal>local0</literal>”..“<literal>local7</literal>”.
