Log Collection (lemmy.procrastinati.org)

I'm in the process of re-configuring my home lab and would like to get some help figuring out log collection. My setup was a hodgepodge of systems/OSes using rsyslog to send syslogs to a syslog listener on my qnap but that's not going to work anymore (partly because the qnap is gone).

My end-goal is going to be as homogeneous as I can manage. Mostly Debian 12 systems (phy and vm) and Docker containers. Does anyone know of a FOSS solution that can ingest journald, syslog, and if it's even possible to send docker logs to a log collector?

Thanks

I use a Graylog/Opensearch/Mongodb stack to log everything. I spent a good amount of time writing parsers for each source, but the benefit is that everything is normalized to make searching easier. I'm happy with it as a solution!

I also use graylog to aggregate logs from various devices (mostly from rsyslog over SSL/TLS). The only downsides for me are the license (not a big problem for a personal setup), and resource usage of the general graylog/elasticsearch stack. I still think it's great.

I use this ansible role to install and manage it.

For simpler setups with resource constraints, I would simply use a rsyslog server as aggregator instead of graylog, and lnav for the analysis/filtering/parsing part
