INF AddEventProvider Directive

An AddEventProvider directive is used within an INF DDInstall.Events section. It specifies characteristics of the Event Tracing for Windows (ETW) providers associated with drivers. This directive is supported for Windows 10 version 1809 and later.

[DDInstall.Events] 

AddEventProvider={ProviderGUID},event-provider-install-section
...

Entries

ProviderGUID
Specifies the GUID value that identifies the provider. This can be expressed as an explicit GUID value of the form {nnnnnnnn-nnnn-nnnn-nnnn-nnnnnnnnnnnn} or as a %strkey% token defined to {nnnnnnnn-nnnn-nnnn-nnnn-nnnnnnnnnnnn} in a Strings section of the INF file.

event-provider-install-section
References an INF-writer-defined section that contains information for registering the provider for this device (or devices). For more information, see the following Remarks section.

Remarks

The system-defined and case-insensitive extensions can be inserted into a DDInstall.Events section that contains an AddEventProvider directive in cross-operating system and/or cross-platform INF files to specify platform-specific or OS-specific installations.

Each INF-writer-created section name must be unique within the INF file and must follow the general rules for defining section names. For more information about these rules, see General Syntax Rules for INF Files.

An AddEventProvider directive must reference a named event-provider-install-section elsewhere in the INF file. Each such section has the following form:

[event-provider-install-section]
 
ProviderName=name
ResourceFile=path-to-file
[MessageFile=path-to-file]
[ParameterFile=path-to-file]
(ImportChannel=channel-name) |
(AddChannel=channel-name,channel-type[,channel-install-section])
...

Each event-provider-install-section must provide ProviderName and ResourceFile. Optionally, specify a list of channels for the provider using any combination of ImportChannel(s) and AddChannel(s), each on a separate line. For more information about channel lists in an INF file, see Specifying a Channel List below. For more information about Windows Event Log channels, see Defining Channels.

Event-Provider-Install Section Entries and Values

ProviderName=name
Specifies the name of the provider. The name cannot be longer than 255 characters, and cannot contain the characters: '>', '<', '&', '"', '|', '', ':', ''', '?', '*', or characters with ASCII values less than 31. In addition, the name must follow the general constraints on file and registry key names. These constraints can be found at Naming a File and Registry Element Size Limits.

ResourceFile=path-to-file
Specifies the path to the exe or dll that contains the provider's metadata resources, expressed as %dirid%\filename.

The dirid number is either a custom directory identifier or one of the system-defined directory identifiers described in Using Dirids.

MessageFile=path-to-file
Optionally specifies the path to the exe or dll that contains the provider's localized message resources, expressed as %dirid%\filename.

ParameterFile=path-to-file
Optionally specifies the path to the exe or dll that contains the provider's parameter string resources, expressed as %dirid%\filename.

ImportChannel=channel-name
Optionally specifies a channel that has been defined by another provider. For more information, see the following Specifying a Channel List section.

AddChannel=channel-name,channel-type[,channel-install-section]
Optionally specifies a channel with a sub-directive that optionally references an INF-writer-defined channel-install-section elsewhere in the INF file. For more information, see the following Specifying a Channel List section.

Specifying a Channel List

You can specify a list of channels for the provider within its event-provider-install-section. You can import a channel or add a channel to the list and the order of these channels is preserved. For more information, see Defining Channels.

The channel-name must be unique within the list of channels that the provider uses. The channel-name must be less than 255 characters and cannot contain the following characters: '>', '<', '&', '"', '|', '', ':', '`', '?', '*', or characters with ASCII values less than 31.

The channel-type can be specified as one of the following numeric values, expressed either in decimal or, as shown in the following list, in hexadecimal notation.

0x1 (Admin)
Admin type channels support events that target end users, administrators, and support personnel. Events written to the Admin channels should have a well-defined solution on which the administrator can act.

0x2 (Operational)
Operational type channels support events that are used for analyzing and diagnosing a problem or occurrence. They can be used to trigger tools or tasks based on the problem or occurrence.

0x3 (Analytic)
Analytic type channels support events that are published in high volume. They describe program operation and indicate problems that cannot be handled by user intervention.

0x4 (Debug)
Debug type channels support events that are used solely by developers to diagnose a problem for debugging.

An AddChannel sub-directive can also reference a channel-install-section elsewhere in the INF file. Each such section has the following form:

[channel-install-section]

[Isolation=isolation-type]
[Access=access-string]
[Enabled=0|1]
[Value=value]
[LoggingMaxSize=max-size]
[LoggingRetention=retention-type]
[LoggingAutoBackup=0|1]

For more information about channel attributes, see ChannelType defined within EventManifest Schema.

Channel-Install Section Entries and Values

Isolation=isolation-type
Optionally specifies the default access permissions for the channel as one of the following numeric values, expressed either in decimal or, as shown in the following list, in hexadecimal notation. If omitted, this defaults to 0x1 (Application).

0x1 (Application)

0x2 (System)

0x3 (Custom)

Access=access-string
Optionally specifies a Security Descriptor Definition Language (SDDL) access descriptor that controls access to the log file that backs the channel.

This string controls read access to the file (the write permissions are ignored) if the Isolation is set to 0x1 (Application) or 0x2 (System), while it controls write access to the channel and read access to the file if the isolation attribute is set to 0x3 (Custom).

Enabled=0|1
Optionally specifies whether the channel is enabled. If omitted, this defaults to 0 (disabled).

Because 0x3 (Analytic) and 0x4 (Debug) channel-type are high volume channels, you should set the Enabled to 1 only when investigating an issue with a component that writes to that channel. Each time you enable a 0x3 (Analytic) and 0x4 (Debug) channel, the service clears the events from the channel.

Value=value
Optionally specifies a numeric identifier that uniquely identifies the channel within the list of channels that the provider defines.

LoggingMaxSize=max-size
Optionally specifies the maximum size, in bytes, of the log file. The default (and minimum) value is 1 MB.

LoggingRetention=retention-type
Optionally specifies whether the log file is 0x1 (circular) or 0x2 (sequential). The default is 0x1 (circular) for 0x1 (Admin) and 0x2 (Operational) channel-type and 0x2 (sequential) for 0x3 (Analytic) and 0x4 (Debug) channel-type.

LoggingAutoBackup=0|1
Optionally specifies whether to create a new log file when the current log file reaches its maximum size. Set to 1 to request that the service create a new file when the log file reaches its maximum size; otherwise, 0. You can set the LoggingAutoBackup to 1 only if the LoggingRetention is set to 0x2 (sequential) and only for 0x1 (Admin) and 0x2 (Operational) channel-type.

Examples

This example shows the event-provider-install sections referenced by the AddEventProvider directives as already shown earlier in the example for DDInstall.Events.

[foo_Event_Provider_Inst]
ProviderName  = FooCollector
ResourceFile  = %13%\FooResource.dll
MessageFile   = %13%\FooMessage.exe

[bar_Event_Provider_Inst]
ProviderName  = BarCollector
ResourceFile  = %13%\BarResource.exe
MessageFile   = %13%\BarMessage.dll
ParameterFile = %13%\BarParameter.dll
ImportChannel = Microsoft-Windows-BaseProvider/Admin
AddChannel    = Bar-Provider/Admin,0x1,bar_Channel2_Inst    ; Admin type
ImportChannel = Microsoft-Windows-BaseProvider/Operational
ImportChannel = Microsoft-Windows-SampleProvider/Admin
AddChannel    = Bar-Provider/Debug,0x4                      ; Debug type

[bar_Channel2_Inst]
Isolation         = 2                                       ; System isolation
Enabled           = 1
Value             = 17
LoggingMaxSize    = 20971520
LoggingRetention  = 2                                       ; Sequential
LoggingAutoBackup = 1
