Displaying and Changing the Text History Settings

In the Operating System monitor, you can not only display the current operating system data for the monitored hosts, but also compare this with previous values. To do this, the Operating System Monitor uses the Central Performance History (CPH), with which the performance values of the monitoring infrastructure are stored and aggregated. However, the CPH is restricted to performance values, and you cannot therefore use it to store the history of text attributes.

To allow the display the history of text attributes that contain operating system data, a corresponding function has been implemented in the Operating System Monitor, with which the associated values for these attributes are stored for a year.

To display or change the settings for the history for text attributes, proceed as follows:

1. Call the operating system monitor (more information: Operating System Monitor.)

2. Choose the system for which you want to display text history settings; more information about selecting the systems: Selecting Operating System Data of Systems, Instances, and Hosts.

3. In the navigation bar, choose  Settings  Text History .

4. The system displays the assignments for all relevant MTE classes for text attributes that contain operating system data. If there is no assignment for an MTE class, the corresponding entry in the Schema for Text History column is empty. The schema SAP 365 Days is available here, with which the values of text attributes are saved once a day and stored for a year.

   Note

   In some cases, all text attributes of a particlar monitoring object are collected in the CPH. In this case, the corresponding line in the list, in the Name of the Attribute column, has the entry <ALL> <name of the monitoring object>. For example, the entry <ALL> CPU means that all text attributes that belong to the monitoring object CPU are collected in the text history.

5. If you want to set or change the assignment for an MTE class, choose the button , and choose the desired schema in the Schema for Text History column of the relevant line.

6. To activate the text history for all text values in the operating system monitoring, switch to change mode and choose the button. The text history is then activated for the following MTE classes:

   • CPU

   • CPUvirtAIX

   • CPUVirtCIMhost

   • CPUVirtCIMvm

   • CPUVirtCIMvc

   • MemoryVirtCIMhost

   • MemoryVirtCIMvm

   • MemoryVirtCIMvc

   • CPUvirtz/OSHost

   • GeneralVirtCIM

   • ClOscolHostname

   If the job SAP_CCMS_TEXT_COLL, which fills the text history with values, has not yet been scheduled, it is now scheduled. To do this, the program RSALTEXTCOL is scheduled with the variant <ALL>. This means that the text values for the MTE classes listed above are collected for all connected systems ( <ALL>). If you want to restrict the systems for which values are collected, you can copy the variant and specify a different system group (more information: System Groups in the Alert Monitor).

For text attributes, the relevant value is underlined in the Snapshot area. To display previous values of the attribute, choose the underlined value. A new screen, Text History then appears, on which previous values of the attribute and their respective time stamps are shown.
