Beyond Sessions: Centering Users in Mobile App Observability

DZone

Observability providers often group periods of activity into sessions as the primary way to model a user’s experience within a mobile app. Each session represents a contiguous chunk of time during which telemetry about the app is gathered, and it usually coincides with a user actively using the app. Therefore, sessions and their associated telemetry are a good way to represent user experience in discrete blocks.

When we discuss code profiling with a team of developers, they often say, "We don't have time to profile our code: that's why we have performance testers ," or, "If your application or system runs very slowly, the developers and performance testers may suggest the infra team to simply add another server to the server farm." Developers usually look at code profiling as additional work and as a challenging process.
