Logging

On the ABAP door logging code mostly wraps the application log in an object-oriented API, as abap-log by Fabian Lupa does among other targets. The rest write elsewhere: a function module's parameters to a table of their own, or entries to Fluentd, Graylog or Loki outside the system.

Overview

SAP SHIPS

The application log records application-specific events: log objects are defined in SLG0, applications write entries through SAP function modules, and SLG1 analyses the log. In ABAP Cloud the Application Log API is the class CL_BALI_LOG.

Not covered: Inside the system. Logs are read in SLG1; the page checked describes the application log's own function modules and transaction.

THE COMMUNITY ADDS

Object-oriented wrappers around the application log, as abap-log by Fabian Lupa and abap-cloud-logger do; exporters that send its entries to outside log systems such as Graylog or Loki, as abap-log-exporter does; and a port for ABAP transpiled to JavaScript, open-abap-bal from open-abap.
