is there an example docker-compose yaml file for simply sending syslog logs to the signoz saas solution? I am struggling to find anything that is not geared toward hosting the whole thing yourself vs using the signoz saas setup. the issue with that is every example in the docs says to use the docker-compose for the full self hosted deployment and to modify the otel-collector section of the docker-compose file. But I do not want to run the whole self hosted setup...

You can use otel-collector-contrib binary/container that has syslog receiver and otlp exporter with headers cofigured with signoz api key.
