7.10. loggly: Using Loggly

The loggly() destination sends log messages to the Loggly Logging-as-a-Service provider. You can send log messages over TCP, or encrypted with TLS.


Example 7.24. Using the loggly() driver

To use the loggly() destination, the only mandatory parameter is your user token. The following example sends every log from the system() source to your Loggly account.

log {
    source { system(); };
    destination { loggly(token("<USER-TOKEN-AS-PROVIDED-BY-LOGGLY>")); };

The following example uses TLS encryption. Before using it, download the CA certificate of Loggly and copy it to your hosts (for example, into the /etc/ssl/certs/ directory.

log {
    destination {
        loggly(token("<USER-TOKEN-AS-PROVIDED-BY-LOGGLY>") port(6514)
            tls(peer-verify(required-trusted) ca-dir('/etc/ssl/certs'))

The following example parses the access logs of an Apache webserver from a file and sends them to Loggly in JSON format.

log {
    source { file("/var/log/apache2/access.log" flags(no-parse)); };
    parser { apache-accesslog-parser(); };
    destination {
           template("$(format-json .apache.* timestamp=${ISODATE})"));

To use the loggly() driver, the scl.conf file must be included in your syslog-ng OSE configuration:

@include "scl.conf"

The loggly() driver is actually a reusable configuration snippet configured to send log messages using the tcp() driver using a template. For details on using or writing such configuration snippets, see Section 5.6.2, Reusing configuration blocks. You can find the source of this configuration snippet on GitHub.
