Log Action Properties

In a message flow, use the log action to construct a message to be logged and to define a set of attributes with which it will be logged.

In the Message Flow Editor, click a log action to display its properties in the Properties view. Use these properties pages to configure the selected log action. The pages are:

The Log page has the following options:

Option
Description
Expression
The message context to be logged through XQuery expressions on context variables.
To create or edit an expression, click <Expression> (or the expression_fragment, if one is already defined) to display the XQuery/XSLT Expression Editor.
Note: The Log action may remove blank spaces in an expression when the message is output to the console or a file. Log action output may be parser dependent.
Annotation
Notes for this log action. These notes are logged along with the result of the previously defined expression.
Severity
The severity of the log message. Options are:
Debug - While your application is under development, you might find it useful to create and use messages that provide verbose descriptions of low-level activity within the application.
Info -Used for reporting normal operations; a low-level informational message.
Warning - A suspicious operation or configuration has occurred but it might not affect normal operation.
Error - A user error has occurred. The system or application can handle the error with no interruption and limited degradation of service.
