Configure Digital Experience Monitoring

Versa-logo-release-icon.pngFor supported software information, click here.

To periodically monitor the end-to-end network and application performance for an end-user device, you can enable digital experience monitoring (DEM) on remote secure access clients. When DEM is enabled on an end-user device, the SASE client collects the following metrics:

  • Device memory, CPU, disk utilization, and battery life
  • WiFi signal strength, and transmit and receive bandwidth per SSID
  • Local network segment metrics such as delay, jitter, and packet loss
  • Internet segment metrics such as delay, jitter, and loss, both end to end and for each hop level
  • Application metrics such as DNS lookup time, TCP and SSL connect times, HTTP latency, time to first and last byte, delay, jitter, and packet loss to application server.

The SASE client sends these metrics to Versa Analytics, which uses them to derive an experience rank, known as the DEM rank, value that ranges from 1 through 100. A value of 1 represents the best experience for the user’s device and applications and a value of 100 represents the worst experience. Versa Analytics also provides in-depth information about the experience at the tenant, gateway, device, and application levels.

To configure DEM, you do the following:

  • Configure a monitoring profile—The monitoring profile includes DEM settings for SASE clients. SASE clients automatically collect DEM metrics based on these settings.
  • Associate the monitoring profile with a secure access portal gateway profile—When the end user registers their SASE client using the secure access portal, the portal automatically pushes the monitoring profile's DEM settings to the user's device.
  • Associate LEF profiles to all secure access gateway profiles—When the SASE client connects to any secure access gateway, the client periodically forwards its DEM data to the gateway. The gateway assembles DEM data from all its clients into DEM logs and forwards them to the destination of the gateways's associated LEF profile. The LEF profile destination must be a Versa Analytics node or an ADC on a Controller that forwards the logs to an Analytics node.

Note that you can export DEM logs only to Analytics nodes. You cannot export them to third-party logging systems, because the logs are in a proprietary format that may not be compatible with the third-party systems.

You can view DEM dashboards from the Analytics tab. For more information, see View Digital Experience Monitoring Dashboards.
