Apache SkyWalking Horizon UI

Horizon UI is the next-generation web UI for Apache SkyWalking. It targets feature parity with the existing booster-ui against the same OAP GraphQL query-protocol and MQE, with a modernized dense dark-first design.

The sidebar on the left of this site is the canonical entry point — every section below has its own page there. This README is the orientation map.

How it's organized

  • Setup — quick start, container deployment, and the horizon.yaml settings operators usually need.
  • Compatibility — OAP version, network ports, required modules, and cluster-status checks.
  • Operate — Cluster Status, Data Retention, OAP Configuration, and Metrics Inspect.
  • Access Control — local users, LDAP login, break-glass access, roles, audit log, and admin pages.
  • Customization — layer menus, dashboard templates, overview templates, and adding a layer.
  • Reference — design target and widget reference for template authors.

Quick orientation

Horizon runs as a browser UI plus a Horizon server process. The browser talks only to the Horizon server; the server talks to OAP for query, admin, and Zipkin traffic. That keeps OAP connectivity, credentials, and compatibility checks in one place.
