Countly lets you track any important metric or milestone in your application via a flexible mechanism called custom events. Flows uses this information (custom events), and lets you see common custom event paths of your users in a birds-eye view.
Flow report is basically a graphical representation of the paths users take through your site, defined by custom events. Report also lets you compare this traffic flow based on several segmentation options such as device, country, platform, or campaign.
Using Flows, you’ll automatically be able to see what common event paths users take without defining each individual path as a funnel.
Flows uses sampling
Due to the high level of processing power it requires, Flows visualizes data using sampling from whole set. Sample is generated using 100.000 events.
Flows also comes with Drill filtering support so that you can see flows for users matching a criteria. Also, if you need you can ignore certain custom events to be a part of flows calculation by defining them in configurations.
You can also define the length of "nodes" vertically and horizontally. In order to define this, click on the cog icon at the right hand side of the screen.
Results are cached
When you make a Flows query, results you see on the user interface are cached for 10 minutes.
