This topic describes the trace events that are generated by Microsoft Dynamics NAV server.
The following list provides useful information about event tracing.
-
The event trace provider is Microsoft-DynamicsNAV-Server. You typically need to provide this name in the monitoring tool that you are using.
-
There are four types of trace events: Windows event log, SQL traces, service calls, and C/AL function calls. Trace event types are identified by a keyword with a corresponding decimal and hexadecimal value. The keywords and values enable you to collect data on specific trace events. Some tools support the hexadecimal values only and other tools support both hexadecimal and decimal.
-
For most trace events, there is separate event for when an operation starts and when it stops. This enables you to determine the duration of the operation. Some monitoring tools, such as PerfView, will automatically return the duration in the stop event.
-
Some monitoring tools might interpret and display the collected event trace differently than others. For more information, see Event Trace Data.
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.
| Keyword | Decimal value | Hexadecimal value |
|---|---|---|
EventViewer | 1 | 0x1 |
SQL Trace Events
SQL trace events track a specific set of SQL statements that are executed from the Microsoft Dynamics NAV Server instance against the Microsoft Dynamics NAV database on SQL Server.
| Keyword | Decimal value | Hexadecimal value |
|---|---|---|
SQLTracing | 2 | 0x2 |
The event data that is collected includes: session ID, tenant ID, the Microsoft Dynamics NAV user, and the SQL statement. For more information, see Event Trace Data.
The following table lists the SQL trace events.
| ID | Event (task/opcode) | What is traced |
|---|---|---|
1 | ExecuteScalar/Start | SQL statements that query a database table and return a single field from a row in the query result. |
2 | ExecuteScalar/Stop | |
3 | ExecuteNonQuery/Start | SQL statements that return a number of rows from a database table |
4 | ExecuteNonQuery/Stop | |
5 | ExecuteReader/Start | SQL statements that return a set of rows from a database table. |
6 | ExecuteReader/Stop | |
7 | ReadNextResult/Start | SQL statements that return the next result from a database query. |
8 | ReadNextResult/Stop | |
9 | ReadNextRow/Start | SQL statements that return the next row in database table. |
10 | ReadNextRow/Stop | |
11 | BeginTransaction/Start | SQL statements that start a database transaction. |
12 | BeginTransaction/Stop | |
13 | Prepare/Start | SQL statements that create a prepared version of the command on an instance of SQL Server. |
14 | Prepare/Stop | |
15 | OpenConnection/Start | SQL statements that open connection to the database from the connection pool. |
16 | OpenConnection/Stop | |
17 | Commit/Start | SQL statements that commit a database transaction. |
18 | Commit/Stop | |
19 | Rollback/Start | SQL statements that cancel the changes in a pending database transaction. |
20 | Rollback/Stop |
Service Call Trace Events
Service call trace events track when Microsoft Dynamics NAV clients run the Microsoft Dynamics NAV objects: Queries, Reports, and XMLports.
| Keyword | Decimal value | Hexadecimal value |
|---|---|---|
ServiceCall | 4 | 0x4 |
The event data that is collected includes: session ID, tenant ID, Microsoft Dynamics NAV user, and the Microsoft Dynamics NAV object ID. For more information, see Event Trace Data.
The following table lists the service call trace events.
| ID | Event (task/opcode) | What is traced |
|---|---|---|
300 | RunQuery/Start | Microsoft Dynamics NAV Query objects that are opened and closed. |
301 | RunQuery/Stop | |
302 | RunReport/Start | Microsoft Dynamics NAV Report objects that are opened and closed. |
303 | RunReport/Stop | |
310 | RunXmlPort/Start | Microsoft Dynamics NAV XMLport objects that are opened and closed. |
311 | RunXmlPort/Stop | |
500 | OpenSession | Microsoft Dynamics NAV Windows clients and Microsoft Dynamics NAV Web clients establish a connection to the Microsoft Dynamics NAV Server instance. |
501 | CloseSession |
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.
| Keyword | Decimal value | Hexadecimal value |
|---|---|---|
ALTracing | 8 | 0x8 |
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.
|
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 |
