wbemListClasses(hsa: HugeStringArray input);
The wbemListClasses method of the Node class retrieves a list of the Web-Based Enterprise Management (WBEM) classes that can be queried for the host machine on which the node specified by the receiver object is running. This is a subset of the full WBEM classes available, as JADE allows only a subset of classes to be queried. The allowed classes are those relating to cache, memory, system, processor, server, disk, and network interface information.
The method inserts strings containing the allowed class names into the huge string array specified by the hsa parameter.
The wbemListClasses method always empties the array before inserting the class names. The caller is responsible for creating and deleting this array.
The strings that are inserted into the huge string array parameter are fully qualified WBEM class names that can be used directly as class names for the other WBEM methods provided by the Node class.
The following example shows the use of the wbemListClasses method.
showWbemClasses()
vars
hsa: HugeStringArray;
str : String;
begin
create hsa transient;
node.wbemListClasses(hsa);
foreach str in hsa do
write "WBEM class name : " & str;
endforeach;
epilog
delete hsa;
end;
An example of the output from this method is as follows:
WBEM class name : Root.CIMV2.CIM_StatisticalInformation.Win32_Perf.Win32_PerfRawData.Win32_PerfRawData_PerfDisk_LogicalDisk WBEM class name : Root.CIMV2.CIM_StatisticalInformation.Win32_Perf.Win32_PerfRawData.Win32_PerfRawData_PerfOS_Cache WBEM class name : Root.CIMV2.CIM_StatisticalInformation.Win32_Perf.Win32_PerfRawData.Win32_PerfRawData_PerfOS_System WBEM class name : Root.CIMV2.CIM_StatisticalInformation.Win32_Perf.Win32_PerfRawData.Win32_PerfRawData_Tcpip_NetworkInterface WBEM class name : Root.CIMV2.CIM_StatisticalInformation.Win32_Perf.Win32_PerfRawData.Win32_PerfRawData_PerfNet_Server WBEM class name : Root.CIMV2.CIM_StatisticalInformation.Win32_Perf.Win32_PerfRawData.Win32_PerfRawData_PerfOS_Processor WBEM class name : Root.CIMV2.CIM_StatisticalInformation.Win32_Perf.Win32_PerfFormattedData.Win32_PerfFormattedData_PerfOS_Processor WBEM class name : Root.CIMV2.CIM_StatisticalInformation.Win32_Perf.Win32_PerfFormattedData.Win32_PerfFormattedData_PerfDisk_LogicalDisk WBEM class name : Root.CIMV2.CIM_StatisticalInformation.Win32_Perf.Win32_PerfFormattedData.Win32_PerfFormattedData_PerfOS_Cache WBEM class name : Root.CIMV2.CIM_StatisticalInformation.Win32_Perf.Win32_PerfFormattedData.Win32_PerfFormattedData_PerfOS_System WBEM class name : Root.CIMV2.CIM_StatisticalInformation.Win32_Perf.Win32_PerfFormattedData.Win32_PerfFormattedData_Tcpip_NetworkInterface WBEM class name : Root.CIMV2.CIM_StatisticalInformation.Win32_Perf.Win32_PerfFormattedData.Win32_PerfFormattedData_PerfOS_Memory WBEM class name : Root.CIMV2.CIM_StatisticalInformation.Win32_Perf.Win32_PerfFormattedData.Win32_PerfFormattedData_PerfNet_Server
