Is there a way to send notifications to skype or google talk (jabber)?

We are also using Skype!! Would be great to enable Skype.

We have no immediate solution for you right now.

You could try a command line client for Jabber and trigger it with a "custom EXE notification". For example this one should do: http://thekonst.net/centericq/

I am not aware of a command line tool for Skype

Hello,

another option would be to build a small C# command-line executable with the jabber.net-Library (LGPL - http://code.google.com/p/jabber-net/).
The following example-code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading;

using jabber.client;

namespace jabjab
{
    class Program
    {

        // we will wait on this event until we're done sending
        static ManualResetEvent done = new ManualResetEvent(false);
        // if true, output protocol trace to stdout
        const bool VERBOSE = false;
        const string TARGET = "";
                
        static void Main(string[] args)
        {
            JabberClient j = new JabberClient();
            // what user/pass to log in as
            j.User = args[0];
            j.Server = args[1];  // use gmail.com for GoogleTalk
            j.Password = args[2];
            string TG = args[3];
            string message = args[4];
                        
            // don't do extra stuff, please.
            j.AutoPresence = false;
            j.AutoRoster = false;
            j.AutoReconnect = -1;

            // listen for errors.  Always do this!
            j.OnError += new bedrock.ExceptionHandler(j_OnError);

            // what to do when login completes
            j.OnAuthenticate += new bedrock.ObjectHandler(j_OnAuthenticate);
            
            // listen for XMPP wire protocol
            if (VERBOSE)
            {
                j.OnReadText += new bedrock.TextHandler(j_OnReadText);
                j.OnWriteText += new bedrock.TextHandler(j_OnWriteText);
            }

            // Set everything in motion
            j.Connect();

            // wait until authentication? (sending a message) is complete
            done.WaitOne();
            j.Message(TG, message);
            
            // logout cleanly
            j.Close();

        }

        static void j_OnWriteText(object sender, string txt)
        {
            if (txt == " ") return;  // ignore keep-alive spaces
            Console.WriteLine("SEND: " + txt);
        }

        static void j_OnReadText(object sender, string txt)
        {
            if (txt == " ") return;  // ignore keep-alive spaces
            Console.WriteLine("RECV: " + txt);
        }

        static void j_OnAuthenticate(object sender)
        {
            // Sender is always the JabberClient.
            JabberClient j = (JabberClient)sender;
            //j.Message(TARGET, "test");
           
            // Finished sending.  Shut down.
            done.Set();
        }

        static void j_OnError(object sender, Exception ex)
        {
            // There was an error!
            Console.WriteLine("Error: " + ex.ToString());

            // Shut down.
            done.Set();
        }
    }
}

Will result in an executable that you could use with 5 parameters (as clear text) from PRTG in the following order:

"jaber_cmd.exe SENDING_USER SERVER PASSWORD RECEIVING_USER MESSAGE"

Following these parameters you can enter the notification message in "", so that in the end the parameters all together for the Exe-Notification in PRTG might look like:

s_user jabber.org password r_user "[%sitename] %device %name %status %down (%message)"

could you provide this executable for those of us without a c# compiler? :)

Is there any way to send to multiple google talk recipients using this method? I can only seem to get it to work with one.

no messages to Skype or Google Talk at the moment, sorry.
