SMMS: SAP Message Server Monitor
You can use the message server monitor to closely monitor the functioning of the message server. The initial screen is identical to the SAP Application Server Overview (SM51). All SAP servers that have logged on to the message server are displayed. To monitor the message server, you can use the Message Server Monitor (transaction SMMS) in the SAP System. You can check and change all the important settings, create and view traces, read statistics, and so on.
Prerequisites
You are logged onto the SAP system, and the message server is running.
Features
The menu option Goto contains all of the functions of the message server monitor.
Display Details
To view detailed information about the client on which the cursor is positioned, choose Goto > Display details.
Information about the Release
To view detailed information about the release of the message server, choose Goto > Release Notes. The release notes provide information on the version of the SAP Message Server, and on the release and Support Package level of the SAP kernel. Kernel information tells you the release of the SAP kernel. Besides kernel release and compile information, this screen provides the following information:
• Update level specifies with which kernel releases the kernel can run in an SAP System. If different application servers are to run with different kernel patch levels in one system, they must all have the same update level.
• Patch number specifies the last Support Package level that is relevant for the component message server.
• Source ID indicates the actual kernel patch level (the number after the full stop).
