Log Levels - SchwarzIT/sap-usi-logging-api Wiki

Log levels control the behavior of the log writer at runtime.

They are a custom construct, that strongly correlates with the "Problem Classes" used by SAPs standard logging API to express the severity of a log message.

Log Level Corresponding Problem Class Logged Problem Classes Description
0 N/A NONE Log is completely deactivated.
1 '1' (Very important) '1' Minimum severity: Very important
2 '2' (Important) '1', '2' Minimum severity: Important
3 '3' (Medium) '1', '2', '3' Minimum severity: Medium
4 '4' (Additional Information) '1', '2', '3', '4' Minimum severity: Additional Information
5 ' ' (Other) '1', '2', '3', '4', ' ' Minimum severity: Other
6 N/A '1', '2', '3', '4', ' ' Additional escalation level. Needed to control creation of data containers.

Types of Log Levels

The logging API knows different types of Log Levels:

Log Level Type Database Table Description
Product specific /USI/BAL_LV_LOBJ Customized by the developer. Defines the bare minimum that needs to be logged no matter what.
User specific /USI/BAL_LV_USER Current setting (maintained directly in production).
Effective N/A Combination of previous Log Levels at runtime. The highest Log Level always "wins".
