In syslog-ng OSE 4.4 and later versions, the syslog-ng-otlp() source and destination make it possible to transfer the internal representation of log messages between syslog-ng OSE instances, using the OpenTelemetry protocol. The syslog-ng-otlp() utilizes the OpenTelemetry protocol for efficient and reliable log message transmission instead of the traditional syslog-ng() drivers, which rely on simple TCP connections.

Advantages of using syslog-ng-otlp():

  • The workers() option makes the scaling of the driver flexible.
  • An integrated application layer acknowledgement is available.
  • Google service authentication (ADC or ALTS), and improved load balancing are supported.

Example: Configure a syslog-ng-otlp() destination on the sender node and a syslog-ng-otlp() source on the receiver node

destination d_syslog_ng_otlp {
  syslog-ng-otlp(url("your-receiver-syslog-ng-instance:4317"));
};

source s_syslog_ng_otlp {
  syslog-ng-otlp(port(4317));
};
