You can prevent the agent from instrumenting the Daasrunner process by creating the environment variable AppDynamics.Processlist and setting it to w3wp.exe. This environment variable acts as an allowlist, where only the processes specified will be instrumented. Then delete the Daas tier and the Daasrunner node on the Tiers & Nodes Dashboard. You might also want to include WebJob processes in this list. See Install the Splunk AppDynamics Azure Site Extension for .NET.
