Datadog is a SaaS observability platform. A single lightweight agent installed on hosts, containers, and Kubernetes nodes collects metrics, distributed traces, structured logs, RUM, synthetics, profiling, and security signals. All signals share a unified tag model: a tag applied once to a host propagates to every signal that host emits, enabling cross-signal correlation without custom glue code.
Watchdog applies statistical anomaly detection continuously across metrics and APM data, surfacing patterns that deviate from baseline without requiring engineers to configure thresholds per metric. Bits AI, the incident triage layer introduced in 2025–2026, reads the full telemetry graph to identify probable root cause and draft incident timelines.
The security suite (Cloud SIEM, CSPM, workload security) runs on the same agent and tagging infrastructure as observability, enabling correlation between a security finding and surrounding infrastructure and application context. Pricing is per host for infrastructure, per ingested/indexed log volume, and per custom metric; cost governance requires active management at scale.
