Do you have to forward large amounts of logs between two syslog-ng instances? OTLP (OpenTelemetry protocol) support in syslog-ng was contributed by Axoflow, and it can solve this problem. Just like the ewmm() destination, syslog-ng-otlp() forwards most name-value pairs, however, unlike a tcp() connection, it scales well with multiple CPU cores. Support for OpenTelemetry was added to syslog-ng a couple of releases ago. OpenTelemetry is an observability framework, mainly used in Linux / Cloud / Kubernetes environments.
