Netdata’s pitch: one install on a server, get 2000+ metrics at 1-second granularity with zero config. Agent is small, dashboards are prebuilt, streaming centralization is available for fleets.
Pick it if: you want real-time per-second resolution and fast time-to-first-dashboard.
Skip it if: you prefer composable stacks (Prometheus + Grafana) for long-term storage & querying flexibility.
