Explore Horizon and plan your migration. https://skywalking.apache.org/blog/banyandb-0-11-0-vectorized-queries-by-default-explained/ Mon, 07 Sep 2026 00:00:00 +0000 https://skywalking.apache.org/blog/banyandb-0-11-0-vectorized-queries-by-default-explained/ The BanyanDB Team Release Storage BanyanDB 0.11.0: default vectorized queries, pluggable trace sampling, schema barriers, and the upgrade order you must not skip. https://skywalking.apache.org/blog/2026-09-07-banyandb-trace-tail-sampling/ Mon, 07 Sep 2026 00:00:00 +0000 https://skywalking.apache.org/blog/2026-09-07-banyandb-trace-tail-sampling/ Kai Wan Tracing Storage SkyWalking 11.0.0 and BanyanDB 0.11.0 add trace tail sampling that runs inside the BanyanDB data node during compaction: each trace is judged as a whole after it is stored, and a dropped trace reclaims space that was already written. https://skywalking.apache.org/blog/2026-09-03-ai-sessionizer-first-look/ Thu, 03 Sep 2026 00:00:00 +0000 https://skywalking.apache.org/blog/2026-09-03-ai-sessionizer-first-look/ Sheng Wu AI Engineering Community Replay existing Claude Code sessions with Apache SkyWalking AI Sessionizer: explore conversations, tool calls, and child-agent activity without installing a Claude Code plugin or changing its configuration. https://skywalking.apache.org/blog/2026-07-06-horizon-ui-ai-assistant/ Mon, 06 Jul 2026 00:00:00 +0000 https://skywalking.apache.org/blog/2026-07-06-horizon-ui-ai-assistant/ Sheng Wu Release AI Cloud Native Horizon UI's new AI Assistant answers questions about your live system with the same charts, topology and tables as the UI — read-only, permission-scoped, and running on a cost-efficient model you bring yourself. https://skywalking.apache.org/blog/2026-06-30-horizon-ui-platform-introspection/ Tue, 30 Jun 2026 00:00:00 +0000 https://skywalking.apache.org/blog/2026-06-30-horizon-ui-platform-introspection/ Sheng Wu Engineering Cloud Native 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). https://skywalking.apache.org/blog/2026-06-30-horizon-ui-access-control-and-security/ Tue, 30 Jun 2026 00:00:00 +0000 https://skywalking.apache.org/blog/2026-06-30-horizon-ui-access-control-and-security/ Sheng Wu Engineering Cloud Native 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. https://skywalking.apache.org/blog/2026-06-30-horizon-ui-customization-and-templates/ Tue, 30 Jun 2026 00:00:00 +0000 https://skywalking.apache.org/blog/2026-06-30-horizon-ui-customization-and-templates/ Sheng Wu Engineering Cloud Native 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. https://skywalking.apache.org/blog/2026-06-30-horizon-ui-localization-i18n/ Tue, 30 Jun 2026 00:00:00 +0000 https://skywalking.apache.org/blog/2026-06-30-horizon-ui-localization-i18n/ Sheng Wu Engineering Community 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. https://skywalking.apache.org/blog/2026-06-30-horizon-ui-getting-started-and-migration/ Tue, 30 Jun 2026 00:00:00 +0000 https://skywalking.apache.org/blog/2026-06-30-horizon-ui-getting-started-and-migration/ Sheng Wu Release Community The finale of the Meet Horizon UI series: install Horizon as a single env-driven container, point it at your OAP, and — if you're on the old UI — swap it in drop-in. Plus the OAP 10.x vs 11.x compatibility matrix: what works on the query port, and what needs OAP 11's admin host. https://skywalking.apache.org/blog/2026-06-29-horizon-ui-alarms-and-incident-triage/ Mon, 29 Jun 2026 00:00:00 +0000 https://skywalking.apache.org/blog/2026-06-29-horizon-ui-alarms-and-incident-triage/ Sheng Wu Metrics Cloud Native Part 10 of the Meet Horizon UI series: the incident-centric active-alarms surface — re-fires merged into one row, the MQE snapshot that fired a rule replayed on a single chart, and the same incident model carried across the topbar badge, dashboards, and the 3D map. https://skywalking.apache.org/blog/2026-06-29-horizon-ui-runtime-rules-and-live-debugging/ Mon, 29 Jun 2026 00:00:00 +0000 https://skywalking.apache.org/blog/2026-06-29-horizon-ui-runtime-rules-and-live-debugging/ Sheng Wu Engineering Metrics 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. https://skywalking.apache.org/blog/2026-06-29-horizon-ui-inspect-cross-layer-query/ Mon, 29 Jun 2026 00:00:00 +0000 https://skywalking.apache.org/blog/2026-06-29-horizon-ui-inspect-cross-layer-query/ Sheng Wu Engineering Metrics 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. https://skywalking.apache.org/blog/2026-06-26-horizon-ui-profiling/ Fri, 26 Jun 2026 00:00:00 +0000 https://skywalking.apache.org/blog/2026-06-26-horizon-ui-profiling/ Sheng Wu Profiling Engineering 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. https://skywalking.apache.org/blog/2026-06-23-horizon-ui-log-explorer/ Tue, 23 Jun 2026 00:00:00 +0000 https://skywalking.apache.org/blog/2026-06-23-horizon-ui-log-explorer/ Sheng Wu Logging Cloud Native Part 7 of the Meet Horizon UI series: two log surfaces — a stored, indexed, trace-correlated log stream with a level histogram, and an on-demand live tail of a Kubernetes pod's container logs. https://skywalking.apache.org/blog/2026-06-23-horizon-ui-browser-errors-and-source-maps/ Tue, 23 Jun 2026 00:00:00 +0000 https://skywalking.apache.org/blog/2026-06-23-horizon-ui-browser-errors-and-source-maps/ Sheng Wu Logging Engineering 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.
