Session Attributes

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.
