IS not visible for monitoring in Manager


I am using Manager 6.5.1. Installation is ok, no errors. I followed all the steps in the administrator’s guide to set up and deploy the WM OMI agents; all ok.
When I add an IS for monitoring in the Manager server, the Manager server says “operational” after a while. Also I can see in the server log of manager server that this specific IS is being pollled and data is being gathered from it. However, in the system view of myWebMethods, I cannot see this IS with its default port. The only thing I can see is the hostname and the controller, satellite and data handler statistics.

How can I get the IS statistics visible in my webMethods UI?
