大佬教程收集整理的这篇文章主要介绍了windows – 获取链接速度 – Win32_PerfRawData_Tcpip_NetworkInterface，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
在类Win32_PerfRawData_Tcpip_NetworkInterface我没有看到任何
我可以用来引用的索引或唯一键
Win32_NetworkAdapterConfiguration或Win32_NetworkAdapter.
我尝试使用theNameinWin32_PerfRawData_Tcpip_NetworkInterface
和Win32_NetworkAdapter`,但它们看起来仍然不同.
例如
VS
任何提示？
先谢谢你,

也许那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'",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
#!/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,{ 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：
