Hello Sawyer
1] a solution manager diagnostics agent can help you deploy the wily bytecode which then reports the J2EE metrics into Wily Enterprise Manager
2] all recent sapinst/ SWPM provide a way to install sap host agent + diagnostics agents
Please refer to Diagnostics Agents - SAP Solution Manager Setup - SCN Wiki
and the Agent Installation Strategy Guide included in sap note 1365123
best regards
Francois
