LibreNMS include syslog-ng in its docker version: https://github.com/librenms/docker#syslog-ng-container
in addition to having one of the best open source software for monitoring, you will have an easy-to-use aggregator for your logs.
Can it monitor containers or some files?

Splunk is not free , right?
Dozzle
I use dozzle to access my containers logs, it's simple and yet works very well for my needs, but OP needs to monitor syslogs and i don't know if it's possible with Dozzle ?
I really like Seq. It supports tons of log types, including GELF, which means you can configure your docker hosts to send all container logs to Seq with just a couple lines in Docker’s daemon.json file.
Setup is pretty simple as a docker compose stack containing the Seq container and a container for ingesting each of the log types you plan to use.
If you wanted to try it out, I’d recommend setting up Seq with seq-input-gelf and seq-input-syslog, and setting up nginx to send access and error logs to syslog as detailed here.
