Using the Traces Page

Once you have instrumented applications to forward trace data to LogicMonitor, you should see the traces and operations display in the Traces page. You can access the Traces page directly from the left hand navigation or by selecting the “Traces” tab for a particular service on the Resources page. (Selecting a Service will redirect you to the Traces page with a filter for that Service.)

The Traces page includes four main parts: an Operations table, an overview Graph, filtering and search options, and an end-to-end view for each operation.

Operations table

The main table in the Traces page shows the specific operations within a trace with 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.

Latency overview graph

The latency overview graph shows the operations plotted by latency. The operations that have an error associated with them are overlaid in red. You can drag your mouse over the graph to automatically filter the table for that selected latency range. Because there may be many operations in a single minute, the you can use the latency overview graph to limit the number of operations displayed in the table to a more digestible number for review.

Filtering and search

You can also use the search bar and filters above the graph to narrow the number of displayed operations. Your filtering options include:

  • Filtering by Resource to see operations for a specific resource.
  • Filtering by Service to see operations that originated from a specific service.
  • Filtering by Operation to see specific operations or functions.
  • Filtering by Error to see operations associated with an error or not.
  • Filtering by Time to see operations over a specific time period.

End-to-end trace view

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

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 selected, 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.

Selecting an operation will also open its detail panel. This detail panel will show:

Tab Description
Info Basic metadata for the operation (such as tags and logs), the resource the operation is associated with, and the service where the operation started.
Logs Operation logs (such as application logs) sent via manual instrumentation, and resources logs (such as infrastructure and application logs) sent via LM Logs.
Alerts Any active alerts for the resource that the operation is associated with.

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