Question

我找到了Determining the network connection link speed 现在我试图关联 Win32_PerfRawData_Tcpip_NetworkInterface 中的数据 Win32_NetworkAdapter （或 Win32_NetworkAdapterConfiguration ）。

在课程Win32_PerfRawData_Tcpip_NetworkInterface上，我没有看到任何内容我可以用来引用的索引或唯一键 Win32_NetworkAdapterConfiguration或Win32_NetworkAdapter. I tried to use the名称in Win32_PerfRawData_Tcpip_NetworkInterface and Win32_NetworkAdapter`，但它们看起来仍然不同。

e.g。

名称：英特尔（R）PRO / 1000 PL网络连接

VS

名称：Intel [R] PRO_1000 PL网络连接

任何提示？

提前谢谢你，

也许这段代码可以帮助你帮助我们：）

# I got the DeviceID of a NIC and use it to get the "NetConnection ID":

$objWMIService = Win32::OLE->GetObject("winmgmts:\\\\$computer\\root\\CIMV2") or die "Exit: WMI connection failed. \n";
$colNicSetts = $objWMIService->ExecQuery(
              "SELECT * FROM Win32_NetworkAdapter Where DeviceID = '$ID'", "WQL", wbemFlagReturnImmediately | wbemFlagForwardOnly);

foreach my $objItem (in $colNicSetts){
    $NetConnID = $objItem->{NetConnectionID};    
}

# => $NetConnID stores "Intel(R) PRO/1000 PL Network Connection".
# Now I tried to get the Link Speed with sth. like that:

$collItems = $objWMIService->ExecQuery(
             "SELECT * FROM Win32_PerfRawData_Tcpip_NetworkInterface Where Name = '$NetConnID'", "WQL", wbemFlagReturnImmediately | wbemFlagForwardOnly);
foreach my $objItem (in $collItems){
    $LinkSpeed = $objItem->{CurrentBandwidth};
}
# "Win32_PerfRawData_Tcpip_NetworkInterface" contains "Intel[R] PRO_1000 PL Network" Connection
# "Intel(R) PRO/1000 PL Network Connection" != Intel[R] PRO_1000 PL Network Connection
# => $LinkSpeed empty

行。感谢您发布短脚本。当你正在研究这个问题时，我正在使用DBD::WMI跟踪不同的音轨并浏览文档以查看是否遗漏了任何内容。

我找不到比标准化名称更好的方法（必须有一个）：

#!/usr/bin/perl

use strict; use warnings;

use DBI;
use Data::Dumper;

my $computer = '.';
($computer) = @ARGV if @ARGV;

my $dbh = DBI->connect("dbi:WMI:$computer", undef, undef,
    { RaiseError => 1},
);

print "=== From Win32_NetworkAdapter ===\n";

my $name = $dbh->selectall_arrayref(
    'SELECT * FROM Win32_NetworkAdapter WHERE DeviceID = 11'
)->[0]->[0]->{Name};

(my $canonname = $name) =~ s/[^A-Za-z0-9]/_/g;

print "Name: $name\nCanonical name: $canonname\n\n";

my $sth = $dbh->prepare(
    'SELECT * FROM Win32_PerfRawData_Tcpip_NetworkInterface'
);

$sth->execute;

print "=== From Win32_PerfRawData_Tcpip_NetworkInterface ===\n";

while (defined (my $adapter = $sth->fetchrow_arrayref )) {
    my $conf = $adapter->[0];
    my $perfname = $conf->{Name};
    (my $canonperfname = $perfname) =~ s/[^A-Za-z0-9]/_/g;
    if ( $canonperfname =~ /^$canonname/ ) {
        print "Name: $perfname\nCanonical name: $canonperfname\n";
        print $conf->{CurrentBandwidth}, "\n\n";
        last;
    }
}

输出：

=== From Win32_NetworkAdapter ===
Name: Intel(R) PRO/Wireless 3945ABG Network Connection
Canonical name: Intel_R__PRO_Wireless_3945ABG_Network_Connection

=== From Win32_PerfRawData_Tcpip_NetworkInterface ===
Name: Intel[R] PRO_Wireless 3945ABG Network Connection - Packet Scheduler Miniport
Canonical name: Intel_R__PRO_Wireless_3945ABG_Network_Connection___Packet_Scheduler_Miniport
54000000

我只是用WMI-Tools查看我的机器，因为我想，它一定很容易...... ;-)
但它不是......

但我在我的机器上发现的是“Win32_NetworkAdapter.Name”+“__”+“Win32_NetworkAdapter.InterfaceIndex”的连接导致“Win32_PerfFormattedData_Tcpip_NetworkInterface.Name =”NVIDIA nForce网络控制器_2“[太空了！]。

来自我的机器的示例：

Win32_NetworkAdapter.DeviceID="13"
Win32_NetworkAdapter.NetConnectionID="Local Area Connection 2"
Win32_NetworkAdapter.InterfaceIndex="2"
Win32_NetworkAdapter.Name="NVIDIA nForce Networking Controller"
Win32_PerfFormattedData_Tcpip_NetworkInterface="NVIDIA nForce Networking Controller _2"

我希望，我理解你的问题，这可能有所帮助？！

我能找到的唯一方法是使用Win32_PnPEntity类获取网络适配器的DeviceName，然后将其转换为InstanceName。这允许您找到可以在其他WMI表上使用的键值（我使用了InterfaceIndex，但Win32_NetworkAdapter类中还有其他选项。

所以在高层：

获取Win32_NetworkAdapter的实例
使用下面两个WMI WQL queries中的一个来获取PnpEntity
通过替换以下内容将Win32_PNPEntity.Name转换为InstanceName：
1. （[
2. ）with]
3. ＃\ / all with _
使用该InstanceName查询Win32_PerfFormattedData_Tcpip_NetworkInterface类

它非常复杂，但由于InstanceName来自PnPEntity名称，这是我能找到获得准确映射的唯一方法。

以下是我能够获得NetworkAdapter的PnPEntity实例的两种方法：

ASSOCIATORS OF {Win32_NetworkAdapter.DeviceID='12'} WHERE ResultClass=Win32_PnPEntity

SELECT * FROM Win32_PNPEntity where DeviceID='PCI\\VEN_14E4&DEV_1684&SUBSYS_1309103C&REV_10\\4&11050A08&0&00E5'
