SecureBytes NOC Stack — Gideon Oteng

Internal observability stack — Grafana dashboards over Prometheus with Node Exporter on every host. Sixty-second scrape interval, push notifications via ntfy.

What it covers

Host layer

Uptime, CPU, memory, disk, and temperature for every node and container. Status rows turn green when a host responds to scrape, red when it does not.

Resource layer

Memory used and percentage, disk at root, stacked side-by-side. Comparing lightweight LXCs against heavy compute boxes is a glance, not a calculation.

Network layer

Inbound and outbound throughput per host, plus separate panels for LAN traffic and WAN egress. Useful for catching a runaway service before it shows up as a complaint.

Node Exporter on everything, no exceptions

Cost is ~10MB of RAM per host. The value is that nothing is invisible when something behaves weirdly. Curating what's worth monitoring up-front is premature optimization for a homelab.

60-second scrape interval

Faster intervals sound better but quintuple storage cost without changing how the data is actually used. 60s is fine for everything except acute incidents, and during those you're on the host with top.

One consolidated dashboard

Separating by category broke the muscle memory — every glance became a navigation problem. One dashboard, scroll to find what you need. Boring, but it works.

Roadmap

→Loki for log aggregation — traces, metrics, and logs on one query surface

→Alertmanager rules tuned by severity — currently every alert fires at the same level

→Sanitized dashboard JSON pushed to a clean public repo
