Example
The following example demonstrates starting a simple agent supporting a MIB variable.
| C# | Copy Code |
|---|---|
private void button1_Click(object sender, EventArgs e) { //Add variable to agent agent1.Mib.CreateVariable(NodeName.sysContact, "Kara Thrace"); agent1.Variables.Values.Add(agent1.Mib.CreateVariable(NodeName.sysContact, "Kara Thrace")); //Start listening for requests agent1.Start(agent1_MessageReceived, null); } private void agent1_MessageReceived(Agent agent, RequestMessage request, object state) { //Create and send a response whenever a request is received agent1.Send(agent1.CreateDefaultResponse(request), request.Origin); } | |
| Visual Basic | Copy Code |
|---|---|
Private Sub button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles button1.Click 'Add variable to agent agent1.Variables.Values.Add(agent1.Mib.CreateVariable(NodeName.sysContact, "Kara Thrace")) 'Start listening for requests agent1.Start(agent1_MessageReceived, Nothing) End Sub Private Sub agent1_MessageReceived(ByVal agent As Agent, ByVal request As RequestMessage, ByVal state As Object) 'Create and send a response whenever a request is received agent1.Send(agent1.CreateDefaultResponse(request), request.Origin) End Sub | |
Remarks
When a SetMessage arrives, the Variable values are updated with information sent by the manager. When a GetMessage arrives, the Variable values are used to intialize the default ResponseMessage. If the Variable values contain OIDs that are in Mib, then the MibNode.Access property is checked for read-write access priviledges to the Agent.Variables list, and the ResponseMessage is constructed accordingly.
