In the previous post FreeBSD: Home NAS, part 10 – monitoring with VictoriaMetrics and Grafana, we configured VictoriaMetrics, node_exporter, Grafana and created a basic dashboard and basic alerts. Now, I want to add a bit more monitoring – to see process CPU/RAM data, SMART information, and ZFS details. Everything written here has been added to… Read More »

FreeBSD: Home NAS, part 10 – monitoring with VictoriaMetrics and Grafana

Finally got around to monitoring. I was interested in running a standard stack with VictoriaMetrics + Grafana + Alertmanager not in the usual Kubernetes with a Helm chart, but simply on the host.

Actually, almost everything regarding my home NAS setup has been done – there is VPN access from various networks, different shares are available, and the security has been slightly tuned.

Got an alert from the monitoring system this morning, indicating that the blog is down: Well, I thought: another one DDoS, not the first time. Investigating the issue I went to the Cloudflare admin, enabled the Under Attack Mode, and started the investigation.

It is time to tidy up SSH on FreeBSD itself and on the clients – laptops running Arch Linux, as I am still using password authentication on my home machines.
