Netdata
Real-time performance and health monitoring agent that installs per-node with near-zero configuration, exposing thousands of metrics out of the box with very low overhead.

⚙ Full Stack
C agent with an embedded high-performance time-series database (per-node, short-retention) and a web dashboard; optional Netdata Cloud provides centralized multi-node views without holding raw metrics itself.
📈 Scaling Analysis
The per-node agent model scales horizontally by construction — adding nodes just means adding more independent agents, with no shared bottleneck. Long-term retention and cross-node correlation are Netdata Cloud's job, not the local agent's, so self-hosted setups trade centralized history for extremely low per-node overhead.
🚀 Running on Nexlayer
Deploy one Netdata pod per monitored node/service, each with access to the host's cgroup/proc info as needed; mirror the official image via mirror.gcr.io. Since each agent is independent, there's no central DB pod required unless streaming to a parent Netdata instance via <podName>.pod:19999.
