Selecting the Views of the Operating System
Monitor
Use
You can use the operating system monitor to display operating system data from monitored hosts on which an operating system collector SAPOSCOL is running. You have the following options for selecting the data to be displayed:
● You can determine the time period for which data is to be displayed. More information: Selecting Current Values and History of Operating System Data.
● You can determine the system and instance about the hosts of which data is displayed. More information: Selecting Operating System Data of Systems, Instances, and Hosts.
● You can use different analysis views to determine which topic area of the monitored operating system data is to be displayed. The different analysis views are described here.
You can display operating system data for the following topic areas:
Analysis View |
Description |
The following data about CPU usage is displayed for every CPU of the host, broken down as percentages by: ● User ● System ● Times in which the CPU had no task to perform or was waiting for an input/output (idle) |
|
The following values are displayed for each host: ● Physically existing and free main memory in kilobytes ● Paging rates (exchange of data pages between the main memory and the overflow storage in a paging file on the hard disk): the number of pages paged-in and paged-out per second with the quantity of data paged-in and paged-out in kilobytes. |
|
The following values are displayed for each host: ● Configured and free swap space (storage space on the hard disk to which data that is not required is paged-out of the main memory) in kilobytes ● Actual and maximum size of the swap space in kilobytes |
|
The name and most important performance data is displayed for all physical disks on a host. |
|
The name and most important performance data is displayed for all LAN interfaces on a host. |
|
The name, capacity, and free storage space in megabytes is displayed for all file systems on a host. |
|
For every host, the most important performance data is displayed for the 40 processes that have used most CPU time. |
|
For every host, the most important performance data is displayed for the processes that are specifically monitored (more information: Monitoring Selected Processes with SAPOSCOL) |
|
The Operating System monitor of the Alert Monitor is displayed. |

If you directly
select a root node of one of the possible periods, 
Snapshot, 
Previous Hours, or 
History, the system displays a summary of the various
