Using the Web Administration Interface 
You can monitor and manage both the SAP Web Dispatcher and the Internet Communication Manager (ICM) from the browser.
The functionality and structure is comparable to the ICM Monitor (transaction SMICM) in AS ABAP.
You do not need the SAP GUI to access the Web administration interface, and you do not have to be logged on to the computer on which the Web dispatcher or ICM is running. You can use it to administer the Web Dispatcher and the ICM in Java-only systems.
Integration
You can also monitor and manage the Web Dispatcher and the ICM using command line programs.
More information: Using the Command Line Programs icmon and wdispmon
Prerequisites
To manage the Web dispatcher and ICM from the browser, the Web administration interface must be set up. The procedure is described in Setting Up the Web Administration Interface.
If the ICM / Web Dispatcher was installed using SAPInst, the Web administration interface is already set up. If you click on the ICM / Web Dispatcher from the MMC, you have to identify yourself. If you install it using SAPInst, Web administration user webadm is created by default. The password is the master password assigned in the installation.
Recommendation
SAP recommends you change the password after the installation. You do this in the Area Menu under Admin Handler.
Features
Enter the URL http(s)://host:admin_port/sap/admin in the browser. Here the host is the computer on which the Web dispatcher or ICM is running and admin_port is the administration port configured with icm/HTTP/admin_<xx>.
Recommendation
For security reasons you should use HTTPS for the administration. If you use HTTP the administrator passwords are transferred unencrypted and can therefore be listened to. It is best to work with client certificates.
When you have logged on, the administration and monitoring interface appears. The only difference in this area between the administration interfaces for the ICM and Web Dispatcher are the headings.
