Is any agent installation required on the productive satellites (managed systems)?
For all systems newly installed based on Web AS 7.0 SR3 or higher, the Diagnostics agent is automatically installed and waits until the Managed Setup Wizard of SAP Solution Manager “wakes him up”. For all other systems, the Diagnostics agent must be installed separately according to the diagnostics agent installation guide on service.sap.com/diagnostics.
In addition, you need to install also the SAP Host Agent, depending on the version of the Diagnostics agent and the used scenarios. More information can be found here.
