Enable Session Replay

This topic describes the prerequisites and the procedure for enabling Session Replay.

Prerequisites

Ensure that your system meets the following requirements:

DESK version 1.163 (SaaS), or Managed version 1.164)
OneAgent minimum version 1.169 on all monitored hosts in your environment
Real User Monitoring enabled for your application
An active DESK Digital Experience Monitoring license
Firewalls configured to allow application/octet-stream content coming from your application; some beacons sent by Session Replay are binary
Managed deployments only: A secondary disk configured to store user session data
The web UI URL has a trusted certificate

Session Replay data must be stored in a different volume, known as the secondary disk; therefore, every node in the cluster must have such a volume allocated to it.

Most sessions are estimated to be around 500kB, the default data retention period is 35 days, and it is always good to have some buffer. Using these estimates, DESK recommends that you calculate the secondary storage size by applying the following formula: Storage size = Sessions per day * Average session size (500kB) * Percentage of sessions to record * Retention period (35) * Buffer (1.5)

To configure the secondary disk:

Mount the directory outside the transaction store. The transaction store and Session Replay folders must not be nested, but parallel. For example, if the transaction directory resides at /mnt1/desk/transaction, the session_replay directory can reside at /mnt2/desk/session_replay.
Assign the ownership of the directory to the desk:desk user.
Set the value of the SERVER_REPLAY_DATASTORE_PATH property in the /etc/desk.conf file to the directory you mounted in Step 1. In this example: SERVER_REPLAY_DATASTORE_PATH = /mnt2/desk/session_replay
Launch the reconfiguration sequentially on every node with your reconfigure.sh file. The path of this file is dependent on environment. An example command is: [Path]/desk/install/desk-managed/installer/reconfigure.sh Managed will be reconfigured and restarted. Upon restart, the new Session Replay storage location will be used.
