Monitoring the Message Server from the Browser

Use

You can use the browser to connect to the message server and display information on the logged on application servers, logon groups, etc.

You simply need to know the host and the HTTP port of the message server. You do not need to access the SAP System.

Prerequisites

The message server has configured an HTTP port (ms/server_port_<xx> is set accordingly - for more information see Message Server Parameters).

Features

The following functions are available:

The message server can return the lists in the formats HTML, ASCII or XML.

·        Server list: This shows all the application servers of the SAP System that are logged on to the message server. Choose /msgserver/text/aslist.

·        List of logon group: All logon groups in the system are displayed. The logon groups are defined in transaction SMLG (see Configuring Logon Groups).  Choose /msgserver/text/lglist.

·        Group per instance: This lists all the instances of the system. For each instance you can see which type of requests it can process (which internal logon groups it belongs to), and on which port this type of request can enter through).

·        Parameter values: This shows the values of the Message Server Parameter. Enter URL: http://mshost:ms_http_port/msgserver/<format>/parameter?parname1[&parname2[&parname3...]], whereby <format> can have the values html, xml or text and parname<n> is a parameter name.

·        Logon groups information: You can display information on individual logon groups. Enter URL: http://mshost:ms_http_port/msgserver/<format>/group?group1[&group2[&group3...]], whereby <format> can have the values html or text, and group<n> is the name of a logon group.

Activities

In the browser enter the URL:

http://mshost:ms_http_port/msgserver/commands

 A table with the functions described above appears. Select the function you want. 

Example

You want to know on which ports the message server receives requests and the type of requests it receives.

This is defined in parameter ms/server_port_<xx>.

Enter the following URL:

http://mshost:ms_http_port/msgserver/text/parameter?ms/server_port_0&ms/server_port_1&ms/server_port_2

You will see:

ms/server_port_0 = PROT=HTTP,PORT=8082

ms/server_port_1 = PROT=HTTP,PORT=8083

ms/server_port_2 = not found

This tells you that the message server has opened ports 8082 and 8083 for HTTP. An HTTPS port is no longer available.

In the Message Server Monitor you can create and deactivate ports while the system is running, as well as just display ports.
