The SNMP provider supports writing to log files and to the debugger.
Note
For more information about installing the provider, see Setting up the WMI SNMP Environment.
A number of registry keys and values define the level and type of logging currently being generated:
Debugging
The HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\WBEM\PROVIDERS\LOGGING registry key contains the logging value that indicates whether information can be written to the debugger. The logging value is set either to 0 to disable debugging output or 1 to enable it. Logging is a REG_DWORD value.
Logging
The HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\WBEM\PROVIDERS\LOGGING\WBEMSNMP registry key holds all of the logging information specific to the SNMP provider. The following table lists the values associated with this key.
| Value | Description |
|---|---|
| Type | REG_SZ Takes one of the following values: "File" = (Default) Sends debugging output to a file. "Debugger" = Sends debugging output to the debugger. |
| MaxFileSize | REG_DWORD Takes integer values from 1024 to 2^32-1. The value is the maximum allowed size in bytes for the log file. If less than 1024, the logging mechanism uses a value of 1024. A minimum size of 8 KB is recommended for this value. When the file reaches the size specified by MaxFileSize, the file name is prepended with a '~' character and a new file is created. Therefore, the maximum disk space required for logging is twice this value. |
| File | REG_SZ Defines the name of the file to which the debugging output is sent when the logging type is set to 'File'. The default value is '<WBEMLOGS>\wbemsnmp.log.' If the <WBEMLOGS> directory cannot be determined from the WMI registry section, the value defaults to 'c:\wbemsnmp.log'. If a share is used, such as \\machine\share\wbemsnmp.log or M:\wbemsnmp.log where M: is \\machine\share, the local SYSTEM account on which WMI runs must have read/write access rights to the \\machine\share. |
| Level | REG_DWORD Takes integer values from 0 through 2^32-1. The value is a logical mask consisting of 32 bits. The following bit masks are combined to define the type of debugging output generated:
