获取链接速度 - Win32_PerfRawData_Tcpip_NetworkInterface

Question

我发现确定网络连接链接速度 ,现在我尝试将Win32_PerfRawData_Tcpip_NetworkInterface中的数据与 Win32_NetworkAdapter(或Win32_NetworkAdapterConfiguration)相关联.

在类上,Win32_PerfRawData_Tcpip_NetworkInterface我没有看到任何可用于引用的索引或唯一键 Win32_NetworkAdapterConfiguration或者Win32_NetworkAdapter. I tried to use the名称inWin32_PerfRawData_Tcpip_NetworkInterface andWin32_NetworkAdapter`,但它们看起来仍然不同.

例如

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？

先感谢您,

也许这段代码会帮助你帮助我们:)

# 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

好的。感谢您发布简短的脚本。当您从事此工作时，我使用DBD::WMI遵循不同的路线，并深入研究文档以查看您是否错过了任何内容。

我找不到比规范化名称更好的方法（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：
