About Tracing

Explore distributed traces and spans with the Trace Explorer to analyze requests across services.

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

Trace Explorer interface showing the Outliers Map, RED Metrics panels, Span Table, and filtering controls

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 three visualizations: a waterfall, a flame graph, and a trace graph that shows how requests flowed across services. Supports navigating cross-trace span links. More here...
  • Trace Views Explorer — the vertical navigation panel running along the left of the Trace 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...
