Lightweight Server Monitoring - One Binary, No Stack

Monitoring a single server should not require running four daemons. Yet the default open-source recipe for “I just want to watch this one box” still looks like this: install node_exporter, stand up a Prometheus server to scrape it, add Grafana to draw the graphs, and bolt on Alertmanager so you actually hear about a full disk. That is a lot of moving parts — and a lot of YAML — for one machine. This post shows a lighter path.

Monitoring CrowdSec with Bleemeo

CrowdSec is an open-source software that allows you to detect peers with malicious behaviors and block them from accessing your systems. It benefits from a global community-wide IP reputation database. Attckers can then be prevented from accessing your resources by deploying bouncers. They are in charge of acting upon actors that triggered alerts: they can block the attacking IP, serve a 403 Forbidden response, and much more.
