Measure Performance #
Embrace also contains a powerful stopwatch and abandonment tracking feature, which we call moments. This mechanism is the same one used to measure application launch performance, which we covered in the Session Reporting section.
Similar to Logs, moments will immediately make a network request.
The performance of the networking calls that moments make are unrelated to the performance of the moment itself.
Moments are best used for tracking critical user flows that are generally short in nature. For more suggestions on what to measure with moments, see the Best Practices page.
Starting a Moment #
Here’s how you start a moment.
In a sample scenario, this is a moment we’re using to measure how quickly an item is added to a
ListView after a user selects the plus button.
You can also start a moment with properties, an identifier, and screenshots. For more on this, check out the API docs.
Limits on Properties
- Property keys have a limit of 128 characters.
- Property values have a limit of 256 characters.
Ending a Moment #
Next, here’s how you end a moment.
A timer is started once you make a call to start a moment. If you end the moment within a configurable threshold, then the timer ends and the client’s measurement is used to report performance. You can end the moment from multiple locations in your app, or from multiple threads.
Tracking Abandonment #
In addition to measuring performance, moments can also measure abandonment. For more on tracking abandonment, see the Best Practices section.
