About Process Engine Logging

During run time, the Process Engine transmits log messages to the Integration Server server.log file (sometimes referred to as the journal log), located by default in the folder Software AG_directory /IntegrationServer/serverName/instances/instance_name/logs. A new file is created for each date of operation, with the date appended to the file name, for example, server.log.20120815.

You may find the contents of the server.log file useful for troubleshooting or debugging purposes. The log levels listed in the following table are available:

Level	Highest message type written to server.log, plus all lower messages
Fatal	Failure that likely affects other operations or products.
Error	Failure that does not likely affect other operations or products.
Warn	Problems that do not end operations, or unexpected or unusual conditions.
Info	Success of an event (this is the default setting).
Debug	Code-level statements recording unusual conditions or decisions.
Trace	Code-level statements recording program flow and state.
Off	No information is written to the server log.

For detailed information about Integration Server logging, see Chapter 8, Setting Up the Server Log, in the PDF publication webMethods Integration Server Administrator’s Guide.

In addition to Process Engine-related messages, the server.log file also contains messages generated by individual process instances. However, you can enable process instance logging for each process model so that messages from instances of that model are sent to a separate log file.
