Compare performance across segments.
Whenever you want to compare the performance of a span across segments you can use “comparison mode”. This allows you to configure multiple filtersets and see and compare the performance. As examples, you can:
To enter “Comparison mode” just click on the “Comparison mode” button at the left of the filter bar:
This adds a second “filterset” on the filter bar. Each filterset can be independently configured and the results will be shown together on the page. So for example you could choose to filter by Chrome running on Windows in one filterset and Safari running on Mac in another, and see all metrics for both in an easy-to-compare way.
The date range is the only filter that cannot be set independently per filterset; changing the date range will affect all the filtersets.
If you want to add a third filterset, click “new filterset” below the bottom filterset.
Currently we allow a maximum of 3 filtersets. If you have a use case that requires more than 3 please let us know.
“Comparison mode” will persist as you navigate around the various performance pages within a BugSnag project. If you leave the project or leave the Performance tab you will lose the comparison settings.
To leave comparison mode, click the “comparison mode” button again. This will leave in place the filters of the topmost filterset. Alternatively, remove all but one of the filtersets using the “remove filterset” X button:
As a shortcut to enter comparison mode when you want to comparing values on a single filter, we offer “quick compare” functionality. To use you must not already be in comparison mode; open any filter and click the “Quick compare” tab heading:
You can now pick multiple values of the filter. In the example below filtersets would be created for Chrome and Edge upon clicking “Apply”:
Sometimes you may want to change a filter across all your filtersets at once. For example you may be comparing across three different browsers and you want to see all the results for a particular release. To do this, click “Apply to all” when selecting the filter you want:
