.net实现snmp获取信息并且形成图表

.net里添加snmp.dll类，图标控件使用第三方的Dundas.Chart.

'获取snmp信息

        Dim mib As New RFC1157.Mgmt()
        Dim sess As New Snmp.ManagerSession("IP", "信息字")
        Dim mi As New ManagerItem(sess, mib.OID("OID"))
        Dim y As Double
        y = mi.Value.ToString()

 

'利用获取到的信息画出图形

 

        Dim x As Integer
        x = 200
        Chart1.Series(0).Points.AddXY(DateTime.Now, y)
        Chart1.ResetAutoValues()
        Chart1.ChartAreas("Default").AxisX.Minimum = DateTime.Now.AddSeconds(-x).ToOADate()
        Chart1.ChartAreas("Default").AxisX.Maximum = DateTime.Now.AddSeconds(x).ToOADate()
        Chart1.Invalidate()
