DataKit (Guance Cloud)

Open-source unified data-collection agent for the **Guance Cloud** observability platform. Supports Linux / Windows / macOS hosts plus iOS / Android / Unity / WeChat mini-program / RUM-web variants. Comprehensive coverage across host metrics, containers, middleware, distributed tracing, logging, and security inspection. Integrates with Guance Cloud's three-signal observability backend (metrics + logs + traces) covering testing, pre-release, and production environments.

Observability platforms typically force operators to pick one signal type per agent (metrics-only Prometheus exporter, logs-only Fluentd / Vector, tracing-only OpenTelemetry collector) — composing the full picture across an organization is operational overhead. DataKit's bet is a unified open-source agent that emits all three signals plus security-inspection telemetry, sized for the Chinese / Asia-Pacific observability market where Guance Cloud is dominant. The S3 / object-storage adjacency: observability telemetry data volume often dwarfs primary application data, and emitting it to S3-compatible object storage tiers is the cost-effective long-retention path.

Full-stack observability for Asia-Pacific deployments using Guance Cloud as the backend, unified host + container + middleware + APM agent in environments where deploying multiple OpenTelemetry-flavored collectors isn't operationally feasible, mobile RUM (Real User Monitoring) via the iOS / Android / WeChat / Unity variants, security-inspection telemetry alongside operational observability, and long-retention observability data on S3-compatible cold-tier storage.
