Structure of the Transaction Log

The transaction log contains the following information:

Field	Description		Example
Date	Date when request was received.	Fields Date and Time are set automatically for system messages. Custom log messages written with the Log Adapter or the report() Function can contain a custom timestamp. This may result in log messages that are not sequential.	`2018-06-06`
Time	Time when request was received.		`08:02:45`
Time Zone	Time zone offset		`+0200`
Transaction ID	Unique ID of the transaction. It is used to trace service calls through the call stack (see Transaction ID). The transaction log contains the first 40 characters of the transaction ID.		`00000002d3b0bdc0000069ce00ff9700ea65376f`
Request ID	Unique ID of request.		`101`
Component Name	Name of component that has been requested (not the name of the xUML service).		`urn:Services.SupportCase.SupportAPI.supportcases.GET`
Elapsed Time	Elapsed time, for each call (service calls, external or internal calls) in milliseconds. If the elapsed time is displayed as "0", the logged step has taken below 1 millisecond of time. The value of elapsed time does not contain: before `SERVICE_ENTER` reading the request data from the network parsing the request body (e.g. SOAP) after `SERVICE_EXIT` creating the response (e.g. SOAP) sending the response to the client		`36`
State	State is either OK or ERROR.		`OK`
Domain	If an adapter has been called, the domain fields contains a value denoting the adapter, for instance SAPRFC, SQL, FILE, SYSAD, POP3, URL, etc. If a service operation has been called, the value is INTERFACE. If a log entry has been triggered by the user via the logger adapter, the value was defined in the UML model.		`INTERFACE`
Log Type	SERVICE_ENTER or SERVICE_EXIT marks the begin/end of a service call. TRANSITION_ENTER or TRANSITION_EXIT marks the begin/end of persistent state transition handling. DOACTION_ENTRY or DOACTION_EXIT marks the begin/end of a persistent state do activity. IO_ENTER or IO_EXIT marks the begin/end of an IO operation, like e.g. an adapter call. If the logger adapter triggered the log entry, the value is CUSTOM.		`SERVICE_EXIT`
Parameter 1 and 2	Parameters, for instance, if the file system adapter has been called, the first parameter corresponds to the executed action (e.g. ReadDirectory) and the second one to the specified file. If the logger adapter triggered the log entry, the first parameter corresponds to the description defined as input for the adapter in the UML model.		`anonymous 2.0.232.75`
Correlation ID	Unique ID that relate an adapter call with the adapter response. The transaction log contains the first 40 characters of the correlation ID. A correlation ID is available for the following: adapters sending a correlation ID: SOAP, URL, SMTP, SAPRFC, Persistent State, JMS services receiving a correlation ID: SOAP, HTTP, SAP, JMS Listener For more information refer to the adapter pages.		`00000011e33a4f8400004fc4000043ac9bc69bee`

Log Levels

The following transaction log levels can be set for each selected xUML service. The higher the log level the more information will be written to the log files. The log levels in the table below are cumulative and are ordered from the lowest to the highest log level. For each log level, also the information of the lower levels is logged. How to view the log is described in xUML Service Transaction Log.

Log Level	Log Types Logged	Description
None		No logging executed.
Custom	CUSTOM	Logs everything that is written by the logger adapter (for more details, see Log Adapter).
Service	CUSTOM SERVICE_ENTER SERVICE_EXIT TRANSITION_ENTER TRANSITION_EXIT DOACTION_ENTER DOACTION_EXIT	Additionally logs the start and the end of calls to a service operation (service interface). For example, calls to SOAP, SAPRFC, or HTTP operations.
IOExternal	CUSTOM SERVICE_ENTER SERVICE_EXIT TRANSITION_ENTER TRANSITION_EXIT DOACTION_ENTER DOACTION_EXIT IO_ENTER IO_EXIT	Additionally logs calls of adapters that communicate with external systems like SAP, SQL, SOAP, etc. For instance, the SQL queries that are sent to the database will be logged as well. Calls via the file system and system adapter are excluded.
IOInternal	CUSTOM SERVICE_ENTER SERVICE_EXIT TRANSITION_ENTER TRANSITION_EXIT DOACTION_ENTER DOACTION_EXIT IO_ENTER IO_EXIT	Additionally logs also calls of adapters to internal (local) resources (file system adapter and system adapter).
