Fluentd + Kibana – Collect Everything, See Everything Why Use These Two Together A lot of systems generate logs. Some generate too much. The problem isn’t getting the logs — it’s making sense of them. That’s where Fluentd and Kibana come in.

Fluentd is the collector — flexible, scriptable, plugin-based. It structures and forwards logs from just about anywhere.
Kibana is the interface — it turns those logs into dashboards, queries, and alerts.

Used together, they turn noisy data into something

Shinken – Modular Monitoring Built on Nagios Principles, But Better What is Shinken Shinken is a distributed monitoring framework built to be compatible with Nagios, but far more flexible and scalable. Instead of trying to replace Nagios outright, it reimagines its architecture: services are decoupled, load is distributed, and components talk over a message bus.

It uses the same configuration format as Nagios, which means old setups don’t need to be rewritten. But unlike Nagios, Shinken can sca

VictoriaMetrics – Time Series Database That’s Built to Keep Up What is VictoriaMetrics VictoriaMetrics is a high-performance time series database built for modern telemetry workloads. If Prometheus starts to choke under load or your long-term retention plan becomes a storage nightmare — VictoriaMetrics is what usually comes next.

It’s fast, lightweight, and designed to ingest millions of metrics per second without falling apart. It stores time series data in an append-only, compressed format th

LibreNMS – Let It Find Your Network for You What is LibreNMS LibreNMS isn’t trying to be a platform. It’s just a smart, open-source tool that helps you keep track of your network without making you build the whole stack yourself.

You install it, point it at your subnet, and within minutes it starts discovering devices — switches, routers, firewalls, even printers if they talk SNMP. You don’t need to add hosts one by one, and you don’t have to define what’s on port 22. It figures things out.
