NIE-SLAAn edge-native open-source probe and SLA platform

NIE-SLA combines Cloudflare Worker services with Rust Agents and presents active checks, Agent availability and multi-region latency as independent data sources for fault isolation.

Project Overview

Deploy

Multiple state sources

Cloudflare reachability, Agent reporting, host-side TCP pings and external node latency are recorded and displayed separately.

Cloudflare server side

The Worker handles API and tasks, Static Assets serves pages, and D1, R2 and Durable Objects cover storage and coordination.

Layered storage

D1 keeps configuration, current state and SLA aggregation; R2 keeps high-frequency history and archives. History queries have explicit caps.

Agent offline queue

Unsent samples go into a local persistent queue and are deleted after the Worker confirms receipt.

Versioned public API

/api/v1 provides a manifest and stable read-only endpoints; third-party frontends need neither admin sessions nor Agent tokens.

Restricted theme runtime

CSS themes only change styles; Canvas themes run in a sandbox and read public data through a restricted message protocol.
