Searching for traces and spans

The Monium Traces interface enables you to search for traces and spans by specified criteria, view a trace by ID, and access aggregation charts by span attributes.

Viewing a trace by IDViewing a trace by ID

If you know the trace_id, enter it in the Enter trace.id field in the top-right corner of the page and click Open. The trace view page will open.

Time rangeTime range

The search is limited to the selected time range. By default, this is the last 24 hours. You can adjust this by selecting a new interval on the timeline.

Trace search modeTrace search mode

This mode retrieves traces that contain at least one span matching your query.

Enter your query in the search bar using the query language syntax. The search bar supports autocompletion: start typing an attribute name to see suggestions and select an attribute, then follow the same process to select its value.

{ project="foo", service="bar", span.duration>=1s }

The results are displayed as a list of traces. For each trace, the list shows its ID, root service, duration, and number of spans. Click the trace to view and analyze it.

Span search modeSpan search mode

This mode retrieves individual spans meeting all criteria of your query. Use this mode to search for specific operations by attributes, regardless of their associated trace.

Span-based search supports all standard trace keys plus custom span attributes (labels). For more information on supported keys and operators, see Query language.

In addition to the span list, the page displays charts for the retrieved spans, showing span counts and duration percentiles. This data can be dynamically grouped by any attribute you select.
