Berserk UI
Browser-based exploration and root-cause analysis for logs, traces, and metrics
Berserk UI is a browser-based tool for exploring logs, traces, and metrics. Write KQL queries directly or use guided filters — either way, the interface is designed to get you from alert to root cause as quickly as possible.
Layout
The UI has two main areas: a collapsible sidebar and the page you open from it.
The sidebar takes you to each page and to your saved queries, dashboards and alerts. Each page shows one view with its own query, filters and time range, and its address is a link to exactly what it shows — see URL Parameters.
Pages
Query
Full KQL query environment with editor, time range selector, and multiple visualization modes.
Logging
Guided log exploration — select a table, add filters, and browse without writing KQL.
Tracing
Find traces by structural pattern with a trace-find builder, then open any trace on its own Trace page to view its span waterfall.
Alerts
Use Alerts to create rules, backtest thresholds and grace periods, and investigate firing groups. The evaluation guide explains completed intervals, recovery, and missing data.
Links and history
A view is saved as you work: reloading a page, or opening its link later, brings back the same query, filters and time range. Opening someone else's link gives you your own copy, so your changes never alter theirs. Browser back and forward move between the pages you opened.
