The logging infrastructure provides a means for either standard reporting of run-time activity or logging diagnostic data for troubleshooting problems based on a set of logging characteristics. OpenEdge writes information to a log file. You control the type and amount of information logged using a combination of log entry types and logging levels. Log entry types are categories of information written to the log file. Logging levels control the amount of logging information for any given log entry type and environment. Log files are described in Log files. Log entry types are described in Log entry types. Logging levels are described in Logging levels.

The logging infrastructure is available for all ABL clients, as well as for the Progress Application Server (PAS) for OpenEdge components. Each of these components use a particular set of characteristics to specify logging within the infrastructure. The following table shows how to specify logging characteristics for each of these components.
