i found a byteagent already present in the installation directory of BOE41 :
/usr/sap/XXX/sap_bobj/enterprise_xi40/java/wily/
i configure this agent to report on wily EM host and go the metric in the introscope console.
But these metrics doesnt seems to report to solman. That strange.
I dont know if i must instal a new agent or configure the bytecode agent found in the DAA agent.
