Modifier and Type	Method and Description
public static PdhUtil.PdhEnumObjectItems	Returns: Returns a List of Strings of the counters for the object. PdhEnumObjectItems(String String that specifies the name of the log file used to enumerate the counter and instance names. If NULL, the function uses the computer specified in the szMachineName parameter to enumerate the names. szDataSource, String String that specifies the name of the computer that contains the counter and instance names that you want to enumerate. Include the leading slashes in the computer name, for example, \\computername. If the szDataSource parameter is NULL, you can set szMachineName to NULL to specify the local computer. szMachineName, String String that specifies the name of the object whose counter and instance names you want to enumerate. szObjectName, int Detail level of the performance items to return. All items that are of the specified detail level or less will be returned. dwDetailLevel) Utility method to call Pdh's PdhEnumObjectItems that allocates the required memory for the lists parameters based on the type mapping used, calls to PdhEnumObjectItems, and returns the received lists of strings.
public static int	Returns: The counter's index if it exists, or 0 otherwise. PdhLookupPerfIndexByEnglishName(String The English name of the performance counter szNameBuffer) Utility method similar to Pdh's PdhLookupPerfIndexByName that returns the counter index corresponding to the specified counter name in English.
public static String	Returns: Returns the name of the performance object or counter. PdhLookupPerfNameByIndex(String Null-terminated string that specifies the name of the computer where the specified performance object or counter is located. The computer name can be specified by the DNS name or the IP address. If NULL, the function uses the local computer. szMachineName, int Index of the performance object or counter. dwNameIndex) Utility method to call Pdh's PdhLookupPerfNameByIndex that allocates the required memory for the szNameBuffer parameter based on the type mapping used, calls to PdhLookupPerfNameByIndex, and returns the received string.
