Agentless RUM data bandwidth usage

fstekelenburg — Tue, 15 Dec 2020 18:21:15 GMT

I was wondering what the average expected network bandwidth utilization is per user session using Agentless RUM, considering Dynatrace Managed.

For Session Replay a guideline of around 100 KB per minute or 500 KB per session is described in the documentation at Session Replay | Dynatrace Help. I imagine sessions without SR result in a fraction of this.

Hi Frans,

You could perhaps have a look at the beacons sent by the JavaScript agent. I've had a look on a production Application. It generated an average of 3 beacons per User Action. Each beacon had a size of 1.1 kB.

Beacons are the monitoring signal sent back to the Cluster. You could do a calculation based on the number of User Actions and beacons sent.
