Traces

Embrace’s Traces solution gives you visibility into any app operation you’d like to track, including duration, success rate, and any contextual metadata collected at runtime that helps debug the root cause of your mobile app's performance issues. With our tool, you can quickly spot any bottlenecks in your app’s architecture, pinpoint areas you need to troubleshoot with high precision, and ultimately deliver a truly optimized user experience.

Root Spans View

The primary page shows all root spans in your app, as well as summary metrics like count, error rate, percentiles of duration, and changes from a previous version.

Traces

To narrow down the spans that are summarized in this view, you can apply the following filters on the root span as well as the child spans:

  • Name
  • Duration
  • Outcome
  • Attributes keys and values
  • Span event names

Root Span Summary View

By clicking on the name of a Root Span in the Root Spans View, you can see a partial listing of all the instances of that Root Span.

Each row represents a specific instance of that Root Span being recorded. You can see its status, unique Span ID, and duration, in addition to start and end times. All of these columns other than the Span ID is sortable.

Clicking on the instance will open up an in-line preview of the details of that instance, including the child spans that it has, their duration, and whether they were completed successfully.

On the right side each row that shows a Root Span instance, there are two icons. The first one takes you to the Root Span Instance View, where you can see all the details about that instance, including attributes and events on each child span. The second one takes you to the specific session in the User Timeline view that this instance ended in so you can see the full context of what happened before and after this Root Span was recorded.

Slow Root Spans

With the Slow Root Spans feature, you can identify performance bottlenecks and prioritize your optimization efforts. Slow Root Spans are instances with both significant occurrences (100 over the last two days) and durations surpassing the 95th percentile of successful spans bearing the same name. You can get the slow Root Spans on the issues page.

Once you click on a Slow Root Span, you can see specific instances of that span.

Span Instances Filters

Filter your instances by durantion or outcome with these filters:

  • All: all instances displayed
  • Slowest: instances completed successfully with duration > p95.
  • Fastest: instances completed successfully and not slow (with duration < p95).
  • Unsuccessful:
    • Error: instances encountered an error.
    • Unknown: insufficient data to determine instance outcome.
    • User Abandon: user navigated away before instance completion.
