.net, not IIS? If it is IIS you have to stop master agent from Services. If it is .net agent it don’t need master agent because it is communicating directly with collector. In such situation .net agent will be visible as long as process is on and on Dynatrace Agent Configured tool it is instrumented.
So do we have any option to make this .net agent disable for sometime? Meantime application team will do their investigation on the issue.They would like to make it invisible for some period of time?
If you want cut off network traffic, network team should disable communication between agent and collector on ports that are used by you (default are 8043 and 9998) . Where such communication is blocked, agent will be disconnected from Appmon server. After disabling such rule, when connection will be established again, there may be need for restarting monitored process again for restoring instrumentation.
