Netdata collects thousands of metrics per second (default update_every=1) across 850+ integrations by automatically discovering data sources without manual configuration. The collector architecture in src/collectors/ and src/go/plugin/go.d/ uses a modular plugin system where external collector processes (src/plugins.d/) are spawned and managed by the core daemon (src/daemon/), each maintaining independent threads that parse system interfaces, container APIs, and application endpoints to extract metrics in real-time.
Unique: Uses a distributed plugin architecture where collectors run as independent processes managed by libuv workers (src/daemon/libuv_workers.c), enabling fault isolation and dynamic scaling without blocking the core daemon. Auto-discovery is built into each collector module rather than a centralized service-discovery system, reducing operational complexity.
vs alternatives: Faster than Prometheus scrape-based collection (1-second vs 15-30 second intervals) and requires zero configuration vs Telegraf's explicit input definitions, making it ideal for dynamic infrastructure where manual config management is infeasible.
Netdata trains unsupervised learning models locally on each agent (src/ml/) to detect anomalies per metric without sending raw data to cloud services. The ML pipeline analyzes metric distributions, seasonality, and trend deviations using statistical models that adapt to each metric's baseline behavior, enabling real-time anomaly flagging at the edge with sub-second latency and zero external dependencies.
Unique: Implements local, per-metric ML models trained on the agent itself rather than centralized cloud-based detection, eliminating data exfiltration and enabling real-time inference with <100ms latency. Uses statistical methods (kernel density estimation, ARIMA-like approaches) rather than deep learning, keeping memory footprint minimal.
vs alternatives: Detects anomalies at the edge without cloud round-trips (vs Datadog/New Relic's cloud ML) and adapts to local baselines automatically (vs static threshold-based alerting in Prometheus), making it suitable for air-gapped or privacy-sensitive environments.
Netdata provides Windows-specific monitoring (src/collectors/windows/) that collects metrics from Windows Performance Counters and WMI (Windows Management Instrumentation) APIs, enabling monitoring of Windows-specific metrics like CPU, memory, disk I/O, network, and application-specific counters. The collector automatically discovers available counters and maps them to Netdata metrics.
Unique: Implements native Windows Performance Counter and WMI integration directly in the Netdata agent rather than relying on external exporters, enabling consistent monitoring interface across Windows and Unix platforms.
vs alternatives: Provides unified Windows/Linux monitoring vs separate tools (Prometheus Windows exporter + Linux node exporter) and includes automatic performance counter discovery.
Netdata provides Kubernetes-aware monitoring through collectors that integrate with Kubernetes APIs (src/collectors/kubernetes/) to discover and monitor pods, nodes, and services. The system automatically detects container metadata, tracks pod lifecycle events, and collects container-specific metrics from cgroup interfaces, enabling visibility into containerized workloads without manual configuration.
Unique: Integrates directly with Kubernetes APIs to discover and monitor pods without requiring separate instrumentation or sidecar containers, automatically tracking pod lifecycle and correlating container metrics with node-level system metrics.
vs alternatives: Simpler than Prometheus Kubernetes SD (no scrape configuration needed) and includes automatic pod discovery with per-container metrics vs manual exporter deployment.
Netdata provides integration points for distributed tracing and APM systems through its API and collector framework, enabling correlation of system metrics with application-level traces. While Netdata itself does not implement tracing, it can ingest trace-derived metrics (latency percentiles, error rates) from external APM systems and correlate them with infrastructure metrics for end-to-end visibility.
Unique: Provides integration points for external APM systems through its API and collector framework, enabling correlation of application traces with infrastructure metrics without implementing tracing itself. Focuses on infrastructure-first observability with optional application-layer integration.
vs alternatives: Simpler than full-stack APM platforms (Datadog, New Relic) for infrastructure monitoring; can be augmented with external tracing systems for application visibility.
Netdata implements a proprietary RRD-like engine (src/database/engine/) that stores metrics in a custom time-series database with configurable retention tiers, page-cache optimization (src/database/engine/cache.c), and SQLite metadata storage (src/database/engine/). The engine uses memory-mapped I/O and journal files (src/database/engine/journalfile.c) to achieve high write throughput while maintaining query performance across historical data without external dependencies like InfluxDB or Prometheus.
Unique: Implements a custom RRD-like engine with page-cache optimization and journal-based writes rather than relying on external databases, enabling agents to function completely offline. Uses memory-mapped I/O for efficient sequential writes and a SQLite metadata layer for dimension/label storage, avoiding the complexity of full-featured TSDB systems.
vs alternatives: Eliminates external database dependencies vs Prometheus (which requires separate TSDB) and provides better write throughput than InfluxDB for per-second collection due to optimized journal-based architecture, at the cost of less flexible querying.
Netdata implements real-time metric replication via a parent-child streaming protocol (src/streaming/) where child agents continuously stream their collected metrics to parent agents, enabling infrastructure-wide dashboards and centralized alerting without requiring a separate metrics aggregation layer. The streaming system uses efficient binary protocols and handles network interruptions with automatic reconnection and backpressure management.
Unique: Implements a native streaming protocol optimized for metric replication rather than using generic message queues or HTTP APIs, achieving sub-second latency and efficient bandwidth utilization. Supports hierarchical parent-child relationships (parent can itself be a child of another parent) enabling multi-level aggregation without centralized bottlenecks.
vs alternatives: Provides real-time metric aggregation without external infrastructure (vs Prometheus federation which requires scrape-based polling) and maintains local agent autonomy (vs centralized collection where agent failure loses all metrics).
Netdata implements a declarative alert system (src/health/) where users define alert rules using a domain-specific language that evaluates metric conditions, triggers notifications, and manages alert state transitions. The health engine evaluates rules every second against collected metrics, supports multiple notification backends (email, Slack, PagerDuty, webhooks), and can synchronize alert configurations with Netdata Cloud (src/aclk/) for centralized management across distributed agents.
Unique: Evaluates alert rules locally on each agent every second without external dependencies, enabling alerts to fire even if cloud connectivity is lost. Supports stateful alert transitions (warning → critical → cleared) with configurable hysteresis, and can synchronize rule definitions with Netdata Cloud for centralized management while maintaining local evaluation.
vs alternatives: Provides local alert evaluation without Prometheus AlertManager overhead and supports richer notification integrations (Slack, PagerDuty, webhooks) out-of-the-box vs Prometheus's limited notification options.
