=> ↺ An rsyslog(d) syslog forwarding setup for Grafana Loki (via Promtail)
Suppose, not hypothetically, that you have a shiny new Grafana Loki setup to store and query your logs (or at least the logs that come from the systemd journal on your Linux machines, and maybe some additional log files on them). Also suppose that you have some OpenBSD machines whose logs you would like to get into Loki. OpenBSD doesn't have the systemd journal, or for that matter a build of Promtail, the Loki log-shipping client. However, Promtail can receive logs via syslog, and OpenBSD can send syslog logs to remote servers (which we're already using for our central syslog server). Unfortunately Promtail only accepts syslog messages in RFC 5424 format, and OpenBSD doesn't send that. Instead, OpenBSD syslog sends what is usually called RFC 3164 format, which is really "the BSD syslog protocol" written down for informational purposes. In order to send OpenBSD syslog to Promtail, we need a converter in the middle (which is the recommended configuration anyway).

=> ↺ Our Prometheus host metrics saved us from some painful experiences
A couple of weeks ago, a few days after a kernel upgrade on our servers, we had an Ubuntu 22.04 server basically die with a constant series of out-of-memory kills from the kernel of both vital demons and random bystander processes. There was no obvious clue as to why, with no program or cgroup consuming an unusual amount of memory.
