Semantic conventions for session

Status: Experimental

This document defines semantic conventions to apply to client-side applications when tracking sessions.

Session is defined as the period of time encompassing all activities performed by the application and the actions executed by the end user.

Consequently, a Session is represented as a collection of Logs, Events, and Spans emitted by the Client Application throughout the Session’s duration. Each Session is assigned a unique identifier, which is included as an attribute in the Logs, Events, and Spans generated during the Session’s lifecycle.

When a session reaches end of life, typically due to user inactivity or session timeout, a new session identifier will be assigned. The previous session identifier may be provided by the instrumentation so that telemetry backends can link the two sessions.
