Logon Load Balancing Monitor (SAP Library - Technical Operations Manual for mySAP Technology)

Logon Load Balancing Monitor

Use

You can use this monitor to monitor the dynamic load distribution. This means that a numerical value for the quality of the dialog system (Logon Load Quality) is calculated from the number of users and the average dialog response time. The higher this number, the better the quality. If you are using logon groups, the application server with the best Logon Load Quality within the selected logon group is always used for the next logon. For information about the distribution of the logon load, see SAP Logon.

Features

The following table provides information about the monitoring tree elements (MTEs) of this monitor:

MTE	Description
Users Logged On	Number of users logged on to one application server
Dialog Response Time	Average processing time for the processing of one dialog step from the point of view of the application server, including the processing time of the database, but not the time for the network transfer or the frontend processing time
Logon Load Quality	Value for the quality of the dialog system (calculated from Users Logged On and Dialog Response Time, among other things); if you are using dynamic load distribution, this value determines which server is used at logon
Logon Load Status	Status attribute with the preferred server of a logon group (the server that is to be used for the next logon, as it has the best Logon Load Quality)

For more information about monitoring the SAP dialog system, see Dialog Overview Monitor and Entire System Monitor.
