希望每个人都在这里。
我正在 C#/ VB.Net 中编写一个 Windows服务,旨在测量带宽消耗 localhost上的所有网站并将其统计信息存储在本地/远程数据库上以上载,下载等。
目标平台仅包括 Windows Server 2003,2003 R2,2008和2008 R2。
我对此事进行了一些搜索,发现了以下内容:
请指导最合适,安全有效的方法/技术或一组此类技术,这些技术可用于衡量每个不同网站的带宽消耗。
请同时分享代码。
此致

我发现一个名为snmpsharpnet的程序集对于在.NET上运行SNMP非常有帮助。
根据我在this article中写的解释,输入带宽使用率可以通过agiven接口计算:
“In”Bandwith用法%=(((ifInOctets(t2)-ifInOctets(t1))* 8)* 100)/(ifSpeed *(t2-t1))
以下是示例代码。
using System;
using System.Collections.Generic;
using System.Text;
using SnmpSharpNet;
namespace Exemple2
{
class Program
{
static void Main(string[] args)
{
/* Get an SNMP Object
*/
SimpleSnmp snmpVerb = new SimpleSnmp("192.168.1.121", 161, "public");
if (!snmpVerb.Valid)
{
Console.WriteLine("Seems that IP or comunauty is not cool");
return;
}
/* Sample of simple Get usage on ifSpeed on interface 10
* TODO : for sure you have to detect the right interface
*/
Oid oidifSpeed = new Oid(".1.3.6.1.2.1.2.2.1.5.10");
/* Getting ifSpeed
*/
Dictionary<Oid, AsnType> snmpDataS = snmpVerb.Get(SnmpVersion.Ver2, new string[] { oidifSpeed.ToString() });
if (snmpDataS != null)
Console.WriteLine("Interface speed \"{0}\" : {1}", oidifSpeed.ToString(), snmpDataS[oidifSpeed].ToString());
else
Console.WriteLine("Not Glop!");
/* Sample of simple Get usage on ifInOctets on interface 10
* TODO : for sure you have to detect the right interface
*/
Oid oidifInOctets = new Oid(".1.3.6.1.2.1.2.2.1.10.10");
Dictionary<Oid, AsnType> snmpData1;
/* Getting it for the first time
*/
snmpData1 = snmpVerb.Get(SnmpVersion.Ver2, new string[] { oidifInOctets.ToString() });
if (snmpData1 != null)
Console.WriteLine("Number of In octets \"{0}\" : {1}", oidifInOctets.ToString(), snmpData1[oidifInOctets].ToString());
else
Console.WriteLine("Not Glop!");
int missed = 0;
while (true)
{
if (missed == 0)
{
/* When you detect a non refesh data, keep the last one
*/
snmpData1 = snmpVerb.Get(SnmpVersion.Ver2, new string[] { oidifInOctets.ToString() });
if (snmpData1 != null)
Console.WriteLine("Number of In octets \"{0}\" : {1}", oidifInOctets.ToString(), snmpData1[oidifInOctets].ToString());
else
Console.WriteLine("Not Glop!");
}
/* Some Wait (less aproximative)
*/
int duration = 5;
System.Threading.Thread.Sleep(duration*1000); // duration seconds
/* Getting it for the Second time
*/
Dictionary<Oid, AsnType> snmpData2 = snmpVerb.Get(SnmpVersion.Ver2, new string[] { oidifInOctets.ToString() });
if (snmpData2 != null)
Console.WriteLine("Number of In octets \"{0}\" : {1}", oidifInOctets.ToString(), snmpData2[oidifInOctets].ToString());
else
Console.WriteLine("Not Glop!");
Counter32 I1 = new Counter32();
I1.Set(snmpData1[oidifInOctets]);
Counter32 I2 = new Counter32();
I2.Set(snmpData2[oidifInOctets]);
Counter32 speed = new Counter32();
speed.Set(snmpDataS[oidifSpeed]);
if (I2.Value == I1.Value)
{
missed += 1;
continue;
}
decimal bandWithUsage = (((decimal)(I2.Value - I1.Value) * 8) * 100) / (speed * duration * (1+missed));
Console.WriteLine("BandWith usage : {0}%", bandWithUsage);
missed = 0;
}
}
}
}
这只是概念验证,现在您可能需要安装BackgroundWorker和计时器。
我希望它有所帮助。
祝你好运
