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).

Hardware Key

You can display the hardware key of your SAP system, which you need to install the SAP license, by choosing Goto > Hardware Keys.

Parameters

You can view all the parameters associated with the Message server by choosing Goto > Parameters > Display. Some of these parameters can be changed dynamically while the system is running; to do this, choose Goto > Parameter > Change. You can display the RZ11 documentation for every parameter. To do this, place your cursor on the parameter name and choose Documentation.

Statistics

You can activate, display, deactivate, or reset Message server statistics. To do this, choose Goto > Statistics. The statistics include information on, among other things, the number of logins, requests received, bytes written and read.

Trace

You can access the following functions of the message server trace by choosing Goto > Trace:

• Display trace file (dev_ms)
• Reset trace file
• Increase or decrease trace level

Services

To display the open ports on the message server choose Goto > Services. On these ports you can access the message server, if you want to Monitor the Message Server from the Browser.

Logon Data

You can display the logon data for the individual SAP application servers that are currently logged on to the message server. To do so, select a server and choose Goto > Logon data > Display.
The number of dialog work processes (in the dialog mode) that the message server needs for load distribution is displayed under Additional data. The relevant dispatcher sends this data to the message server when the server is started.

Expert Functions

These functions are required for analysis performed by SAP, and are not described further here. Exceptions to this are the server functions Shut Down Server (Hard), Shut Down Server (Soft,) Terminate connection, Deactivate and Activate. These functions control the state of the application server.
