我發現了一個大會呼籲snmpsharpnet至極是非常有幫助的。NET的頂部,SNMP玩。
根據我在this article寫的說明輸入帶寬的使用率可以通過用於agiven接口來計算:
「以」 在帶寬%使用率=(((的ifInOctets(T2)-ifInOctets(T1) )* 8)* 100)/(ifSpeed *(T2-T1))
這裏是一個示例代碼。
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;
}
}
}
}
這只是概念驗證,現在您可能需要更新BackgroundWorker和計時器。
我希望它有幫助。

你的代碼看起來很有希望!我會嘗試一下併發布結果。 :) – 2011-03-18 08:51:32
我幾個月前用Perl做了同樣的事情,它的工作原理就像一個魅力,但是睡眠時間需要更高,否則你總會得到零值。如果你想要更精確的值,你可以選擇WMI或更好的NFDump。既然你正在使用Windows Server客戶端,我一定會去WMI。 – raz3r 2012-03-23 10:25:03
作品像一個魅力:)謝謝 – 2012-09-13 12:40:57
