Log Configuration with the SAP NetWeaver
Administrator
Use
The Log Configuration tool in the SAP NetWeaver Administrator provides options for configuring online the severities of log controllers in the whole system or in a certain system instance.
Features
Log Controllers
Log controllers are objects that manage the writing of log and trace messages. Two types of log controllers are available:
● Location – describes messages that originate from delimited source code areas. It is used to store and emit trace messages. Since trace messages are meant for developers and support engineers, they are organized along code packages. In the SAP NetWeaver Administrator, locations are named as tracing locations.
● Category – describes messages specific to distinguished problem areas. It is used to store and emit log messages. Typical problem areas are: databases, networking, security auditing, and others. In the SAP NetWeaver Administrator, categories are named as logging categories.
The configuration steps for both logging categories and tracing locations are the same. Therefore, the steps in the configuration procedures treat them as a whole.
Severity levels
The severity denotes the level of importance or relevance of a certain message.
The increasing order of the severity levels is:
● ALL – The lowest severity. Controller with such a severity logs all the messages regardless of their severity.
● DEBUG – For debugging purpose, with extensive and low level information.
● PATH – For tracing the execution flow, for example, used in the context of entering and leaving a method, looping and branching operations.
● INFO – Informational text, mostly for echoing what has already been performed.
● WARNING – Announces that the application can recover from an anomaly and fulfill the required task, but needs attention from a developer/operator.
● ERROR – Announces that the application can recover from an error, but it cannot fulfill the required task due to the error.
● FATAL – Announces that the application cannot recover from an error, and the severe situation causes fatal termination.
● NONE – The highest severity. Log controllers with such a severity suppress all the messages logged into them, except for the messages with the same severity.
