Traces Page Overview

Last updated on 08 November, 2022

The Traces page displays the traces and operations of the trace data from your instrumented applications. You can access the Traces page from the Navigation sidebar or from a service in Resources.

The Traces page displays the trace data using the following visual components:

  • Traces Graph—Displays trace data allowing you to visualize how your traces are performing
  • Traces Table—Lists the spans from your trace data, sorted by time

You can use filters to narrow your trace data. When filters are applied to the trace data, the Traces Graph and Traces Table update based on the options selected in the filters. From the Traces Table, you can access the end-to-end trace detail screen.

Traces Graph

The Traces Graph allows you to visualize how your traces are performing over time using the following:

  • Latency—The Traces Graph displays the operations plotted by latency. 
  • Time Series—The Traces Graph displays spans and errors ingested over time.

You can select “Latency” or “Time Series” to view the trace data in the Traces Graph for the operation you select.

You can narrow the data in the graph by clicking and dragging your cursor over the desired data. The graph zooms in on the selected data.

Traces Table

The Traces Table displays the specific operations within a trace using the following details:

Field Description
Operation The name of the operation, which is set during instrumentation.
Time The time that the operation occurred. You can sort the table in ascending or descending time order.
Duration (ms) The duration of the operation in milliseconds.
Service The service where the operation originated. If there are errors associated with the service, you will see an icon to indicate the severity.
Resource The resource associated with the operation. If there are errors associated with the resource, you will see an icon to indicate the severity.

End-to-End Trace View

Selecting a specific operation displays the end-to-end trace that operation participates in along with other operations in the trace. The end-to-end view focuses on the operation you select, but you will also see the operations before and after it in the timeline.

For each operation, this view displays the Service name and Operation name followed by the duration and error status of the operation. The length of the bar indicates its duration, while the color of the bar indicates the error status of the operation.

End-to-end trace view and detail panel for the selected operation.

Selecting an operation opens the detail panel for that operation. This detail panel shows the following:

  • Overview— Displays basic metadata for the operation (such as tags and logs), the resource the operation is associated with, and the service where the operation started.
  • Alerts— Displays a list of any active alerts for the resource that the operation is associated with.
  • Logs— Displays operation logs (such as application logs) sent via manual instrumentation, and resources logs (such as infrastructure and application logs) sent from LM Logs. See LM Logs for more information.
  • Metrics— Displays the metrics (Duration, OperationCount, ErrorOperationCount) of the operations associated to the service namely in a graph. The metrics displays for a time range (+/- 15 minutes) of the ingested span. You can zoom in on each graph. The following image displays the Metrics tab.

You can use this contextual information to troubleshoot issues identified by the traces (using duration or error status).
