Meet Horizon UI · 13/17: Platform & Cluster Introspection
Part 13 of the Meet Horizon UI series: three read-only introspection surfaces that turn the lens on the backend itself — Cluster Status (is OAP healthy, across which ports), OAP Configuration (the effective runtime config), and Data Retention (how long each class of data lives, including BanyanDB's hot/warm/cold lifecycle).

Meet Horizon UI · 14/17: Access Control & Security
Part 14 of the Meet Horizon UI series: Horizon's own access control — server-enforced RBAC with four roles, local and LDAP/AD authentication, an append-only audit log, an LDAP-only break-glass hatch, and five themes. All of it lives in Horizon's BFF and works the same on any OAP version.

Meet Horizon UI · 15/17: Customization — Config-Driven Layer Templates
Part 15 of the Meet Horizon UI series: the whole console is driven by templates you can edit. Open any layer or overview as a template, change its widgets, components, and labels in a local draft, preview it, and publish it to OAP for the whole org — with diff-before-push and export/import.

Meet Horizon UI · 16/17: Localization in Eight Languages
Part 16 of the Meet Horizon UI series: Horizon speaks eight languages, not by re-translating on every render but as server-side overlays merged onto the same templates. Pick a language from the topbar, or click any widget on the Translations admin to translate it — while every value OAP supplies stays verbatim.

Meet Horizon UI · 11/17: Runtime Rules & Live Debugging
Part 11 of the Meet Horizon UI series: edit SkyWalking's OAL/MAL/LAL analysis rules in the browser and hot-apply them to the running cluster with a fenced, recoverable rollout — then step those same rules against live data in the three-tab Live Debugger to see exactly what they compute.

Meet Horizon UI · 12/17: Inspect — Cross-Layer Query Power-Tools
Part 12 of the Meet Horizon UI series: the Inspect family under Operate — a metric catalog and MQE board that shows which rule defines every metric, plus layer-less trace and log finders that query across the whole deployment without picking a layer first.

Meet Horizon UI · 9/17: Five Profilers, One Flame Graph
Part 9 of the Meet Horizon UI series: SkyWalking's five profilers — trace, async (JVM), eBPF, Go pprof, and network — four of them pouring into one shared flame-graph and stack-tree engine, and the fifth rendering a process honeycomb instead.

Meet Horizon UI · 8/17: Browser Errors & Source Maps
Part 8 of the Meet Horizon UI series: the browser agent's JavaScript-error feed, and the capability that makes it useful — resolving a minified production stack back to your original file, line, column, symbol and source, frame by frame.

Meet Horizon UI · 5/17: The 3D Infrastructure Map
Part 5 of the Meet Horizon UI series: a single WebGL view of your whole deployment — every layer's services as cubes stacked on tiers, with live traffic, alarm beacons, and the calls between them.
