c) Service Manager : web based tool to manage services and policies . Like registering services and assigning policies to these services.
d) Real Time Monitoring Console : web based tool to for real-time monitoring of HTTP/S traffic processed by OEG
e) Traffic Monitor

7. To start OEG Server use INSTALL_DIR/posix/bin/enterprisegateway (Unix/Linux) , INSTALL_DIR\win32\bin\enterprisegateway
8. Default URL for OEG is http://HOST:8090/ and username password is admin/changeme
