Changing log settings for core CMDB components


As an administrator, you can change the log file settings from the CMDB Core Configurations screen. You do not require file system access to make these changes. The logging for the core CMDB components such as the CMDB Engine, Normalization Engine, and Shared Plugins is enabled by default. 

For any change to logging configurations to take effect, you do not need to restart the AR System. As a result, you can eliminate the downtime while enabling detailed logs.

Both the plugin server and the shared plugins have logging settings that you can customize for various troubleshooting scenarios. The plugin server hosts the shared CMDB plugins on port number 9556. 

Important

When you restart AR System server, changes to the logging configuration for CMDB Engine and CMDB Services pages in Configurations > Core Configurations, are not saved. In such cases, re-enter the changes to the logging configuration and click Save.

To access log settings

  1. From CMDB Portal, select Configurations > Core Configurations.

  2. On the Core Configurations screen, select a core component and click the Logging section.

To change log levels

  1. From CMDB Portal, select Configurations > Core Configurations.

    From the list of components, select the core component for which you want to change the log level.
    For example, if you want to change the log level for CMDB Impact Simulator, select Impact Simulator from the list of plug-ins and components on the Core configurations screen.

  2. Select Logging > Log Level and select the log level.
  3. Save the changes.

    Important

    If the logging values are not displaying correctly in the CMDB Portal, check the logging level in the Centralized Configuration Settings in AR System Administration Console. If the logging value is entered in any other format other than in title case, re-enter the value in title case. For example, if the logging level is set to WARN or warn, change it to Warn. For more information, see Configuration settings.

You can change the log settings for the following components and plug-ins from Configurations > Core Configurations:

CMDB Engine 

Event Channel

Normalization

USM

Reconciliation
