Function documentationmsmon Monitoring Program

 

You can use the msmon monitoring program to monitor the message server at operating system level.

Integration

The msmon program offers the same functions at operating system level as the message server monitor in AS ABAP (transaction SMMS).

Prerequisites

You have access to the host on which the message server of your SAP system is running and you can log on there with user <sid>adm.

Features

The call of the message server monitor without arguments displays the permitted arguments and options:

Usage msmon

pf=<profile> : profile to connect to server

name=<SID> : SID get server/host from DEFAULT.PFL

[-mshost mshost] : msg server host

[-msserv msserv] : msg server services

[-customer] : enable customer mode

Under this:

q - quit

m - menu

->

As a rule you use q to quit the message server monitor and m to get to the menu (next level up).

After you have called msmon with the system ID, the profile, or the host/port of the message server, you get a list of the application servers logged on to the message server.

If you then enter m and press Return, you reach the main menu:
