Selfhosted

I asked this of the #homelab fediverse a few weeks back, as I was starting to deploy a family of apps to my "homelab" which is really a raspi3b with a repurposed spinny-platty laptop drive connected to some cloudflare tunnels. I settled on VictoriaLogs and VictoriaMetrics for the actual observing bits, fluentd for a log driver (I'm using docker-compose), and postgres-exporter, node-exporter, and handrolled metrics endpoints for prometheus metrics exposure (victoriametrics can do the metrics scraping itself).

If I were to change anything at the moment, I'd replace fluentd first, as some of the filters I use require the ruby interpreter and that seems a little heavy for my setup. Second I'd probably move to Grafana for dashboards. Alerting is gaping hole in the setup right now; I've used alertmanager in the past and not been particularly happy with it, but I don't have a specific alternative I would suggest at the moment. If I had a much larger deployment, especially spread across multiple nodes, I'd consider ProxMox, but I'm just not there yet.

There were other suggestions that I didn't go too deep into, especially after I got something working sufficiently, including dockhand, gatus and beszel, but so far (and to my surprise) having what I described above all running in containers on this little pi is doing the trick.
