The SAS Environment Manager Agent on the middle-tier machine is the agent that discovers the SAS Application Server Tier resource. If you have problems with discovering or monitoring that resource, check the agent.log on the middle-tier host. If there are no clues in there, you can set the following logger in agent.properties to get more information:
log4j.logger.com.sas.emi=DEBUG
You will need to restart the agent after setting DEBUG.
agent.log is located at <sas-configuration-directory>\Lev1\Web\SASEnvironmentManager\agent-5.8.0-EE\log
agent.properties is located at Lev1\Web\SASEnvironmentManager\agent-5.8.0-EE\conf
