# Session (classic) A *session* is a temporary connection detected between two devices that are communicating with each other. A session is always associated with a start event marking the beginning of an exchange of information, and an end event when the communication channel between the two systems is terminated. There is no directional bias, the data flow can travel in each direction and is not limited to one instruction. As long as the session is established, information can transit from one side to the other. Once reported, it is associated with a duration attribute and various quality measurements. *** RELATED TASKS * [Session performance](/platform/references/references-classic/database-information-and-organization-classic/session-performance-classic.md) * [Configuring Session Performance Storage](/platform/configuring_nexthink/configuring-your-platform/configuring-your-platform-classic/configuring-session-performance-storage-classic.md) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
