This monitor displays a section of the Operating System Monitor, which displays all of the values collected by the operating system collector SAPOSCOL. You can use this monitor to monitor application servers and host systems of your choice and to check whether there is still enough free disk space available. The values are collected by the operating system collector SAPOSCOL. You can also monitor this data with the operating system monitor, which is assigned as the analysis method for most of the nodes of this monitor.


To be able to display operating system data for a particular server with this monitor, the operating system collector SAPOSCOL must be installed on that server (see Installing the Operating System Collector SAPOSCOL).


The monitor contains the following monitoring tree elements (MTEs):

MTE Name (MTE Class) Meaning

Name (FilesystemName)

Name of the file system

Freespace (FilesystemFreeSpace)

Free disk space in the file system

Percentage_Used (FilesystemPercentageUsed)

Usage of the available storage space for the file system as a percentage


You can explicitly exclude file systems from the operating system collector monitoring. For more information, see Central Monitoring of Operating System Data.
