Posting messages over HTTP

Version 3.7 of syslog-ng OSE can directly post log messages to web services using the HTTP protocol. Error and status messages received from the HTTP server are forwarded to the internal logs of syslog-ng OSE.

The current implementation has the following limitations:

This destination is only supported on the Linux platform.
Only HTTP connections are supported, HTTPS is not.
This destination requires Java. For an http destination that does not use Java, see http: Posting messages over HTTP without Java.

Declaration

java(
    class-path("/syslog-ng/install_dir/lib/syslog-ng/java-modules/*.jar")
    class-name("org.syslog_ng.http.HTTPDestination")

    option("url", "http://<server-address>:<port-number>")

);

Example: Sending log data to a web service

The following example defines an http destination.

destination d_http {
    java(
        class-path("/syslog-ng/install_dir/lib/syslog-ng/java-modules/*.jar")
        class-name("org.syslog_ng.http.HTTPDestination")

        option("url", "http://192.168.1.1:80")
    );
};

log
    { source(s_file); destination(d_http); flags(flow-control); };

NOTE: If you delete all Java destinations from your configuration and reload syslog-ng OSE, the JVM is not used anymore, but it is still running. If you want to stop JVM, stop syslog-ng OSE and then start syslog-ng OSE again.
