About Tracing

The Tracing Explorer lets you investigate distributed traces — the records of how requests travel through your services.

Homepage

It is organized into the following areas:

Global Controls

  • Filter — narrows the span data shown across all views. More here...
  • Command Menu — provides quick access to common actions and navigation. More here...
  • Time Picker — sets the time range for all views. More here...

Span Visualizations

  • Outliers Map — a four-dimensional visualization that encodes time, duration, span concentration, and error rate simultaneously, making it easy to spot performance outliers and error spikes at a glance. More here...
  • RED Metrics — a three-panel time series dashboard showing span throughput, error counts, and duration percentiles over time, based on the RED monitoring methodology. More here...

Span List Views

  • Table — displays spans as a tree that reflects parent-child relationships within a trace, with configurable columns and durations expressed relative to a reference span. More here...
  • Groups — aggregates spans by a selected attribute (e.g., service.name) and displays per-group ERROR metrics (count and percentage) and DURATION metrics in a sortable table. Each row is drillable, allowing you to navigate into the spans for that group. More here...
  • Triage — performs automated comparative analysis to identify attribute values that are disproportionately concentrated in erroneous or slow spans versus a baseline group. More here...

Span Detail Panels

  • Span Sidebar — a context-sensitive detail panel that opens when a span is selected, surfacing attributes, resource metadata, events and logs, span links, and raw OpenTelemetry payload data across dedicated tabs. More here...
  • Trace View — provides a detailed look at a single trace in either a waterfall or flame graph visualization, with support for navigating cross-trace span links. More here...
  • Trace Views Explorer — the vertical navigation panel running along the left of the Tracing Explorer that organizes saved span views into Favorites, Built-in, and Custom sections, providing quick access to pre-configured and user-defined perspectives on span data. More here...
