This topic describes the trace events that are generated by Microsoft Dynamics NAV server.

The following list provides useful information about event tracing.

Windows Event Log Trace Events

Windows Event Log trace events track errors, warnings, and information messages that provide information about the condition or state of Microsoft Dynamics NAV Server instances. These events are also logged in the Windows Application event log of the computer that is running Microsoft Dynamics NAV Server. For a complete list of the events, see Monitoring Microsoft Dynamics NAV Server Events in the Windows Event Log.

C/AL Function Trace Events

C/AL function tracing events track the execution of C/AL functions and statements on the Microsoft Dynamics NAV Server instance.

The event data that is collected includes: session ID, tenant ID, Microsoft Dynamics NAV user, C/ALC/AL function, C/AL statements, and line number. For more information, see Event Trace Data.

Important
If the Microsoft Dynamics NAV Server instance is not configured for full C/AL function tracing, then only root-level C/AL function will be traced. Statements and C/AL functions that are called from functions will not be traced. By default, the Microsoft Dynamics NAV Server instance is not configured for full C/AL functionf tracing. For information about how to specify full C/AL function tracing, see Configuring Microsoft Dynamics NAV Server.

The following table lists the C/AL function tracing events.

ID Event (task/opcode) What is traced

400

ExecuteALFunction/Start

C/AL functions that are called.

401

ExecuteALFunction/Stop

402

ExecuteALFunctionFailed

Errors that occur when executing C/AL functions. The errors can be caused by exceptions or ERROR Function (Dialog) calls.

403

ExecuteALFunction

C/AL statements that are executed.

Important
This trace event is only traced when the Microsoft Dynamics NAV Server is configured to full C/AL function tracing.

Event Trace Data

The following table lists the arguments that make up the data collected for trace events. When viewing event trace data, the way that the arguments are interpreted and displayed can vary depending on the tool that you use.

Argument Description Trace event type

connectionType

Specifies the RoleTailored client that has established the connection to the Microsoft Dynamics NAV server instance. Values include Microsoft Dynamics NAV Windows client and Microsoft Dynamics NAV Web client.

Service calls

failureMessage

Includes the error message that is returned when a C/AL function fails.

C/AL function trace events

functionName

Specifies the C/AL function that was executed.

C/AL function trace events

lineNumber

Specifies the line number of the statement in the C/AL code of the Microsoft Dynamics NAV object that was executed.

C/AL function trace events

message

Specifies the error, warning, or information message text that was issued for a Windows event log trace on the Microsoft Dynamics NAV Server.

Windows event log trace events

objectId

Specifies the ID of the Microsoft Dynamics NAV object that was executed in the session.

Service calls trace events

C/AL function trace events

objectType

Specifies the Microsoft Dynamics NAV object type that executed by a C/AL function or statement. Values include the following: CodeUnit, Page, Query, Report, Table, and XMLport.

C/AL function trace events

sessionId

Specifies the ID that is assigned to the session that is used by the operation. Each operation establishes a session with the Microsoft Dynamics NAV Server instance from a connection in the Microsoft Dynamics NAV Server's connection pool.
