Structure of the Display in the Operating System Monitor 

Use

The operating system monitor is a one-screen transaction that has as few additional menus as possible. This makes operation significantly easier and more intuitive.

Simply put, the operating system monitor display consists of three parts:

●      Data Source (top left)

In this part, you define the host from which you want to display operating system data.

●      Analysis Views (bottom left)

In this part, you define the time period and topic area for which you want to display operating system data.

●      Output Area (right)

The operating system data that matches your selection in the above areas is displayed here.

Activities

The individual screen elements of the operating system monitor have the following meanings:

Data Source

In this area, you specify the hosts for which you want to display operating system data in the output area. To do this, choose one of the available systems, instances, or hosts. When you do so, the system displays the data for the host(s) on which the corresponding system or instance is running. More information: Selecting Operating System Data of Systems, Instances, and Hosts.

Analysis Views

In this area, you determine which data you want to display from the selected data source:

●      You can specify the period for which you want to display the collected data:  Snapshot,  Previous Hours, or  History. More information: Selecting Current Values and History of Operating System Data.

●      You can determine which topic area of the operating system data you want to display.

●      In the  Additional Functions subtree, you can also display additional operating system data and administer the Operating System Collector SAPOSCOL directly from the operating system monitor:

●      In the  Settings subtree, you can display and, if necessary, change the configuration settings of the Central Performance History (CPH) and the text history.

The CPH is the “long-term memory” of the monitoring performance data and therefore the source of the data that is displayed in the  History subtree in the operating system monitor. More information: Displaying and Changing CPH Settings in the Operating System Monitor.

The text history allows you to keep a history of displayed values for text attributes. More information: Displaying and Changing Text History Settings.
