More on Graphical Ping

We've always wanted to produce a good graphical ping tool and now I think we've finally got one. Enter an IP and press start -- and away it goes. The cool thing about it is that you can monitor congestion, in other words you can watch the round trip travel time go up and down as you browse the web. If dropouts occur, you get a little red triangle appearing in the graph where a packet should have been.

The graph is cool because you can see at a glance what's happening. Did I mention you can print it? yes you can, but you have to stop it from collecting data first. And you can also 'window' the graph. What I mean is that you can enter in the maximum number of points you want to see and then the older points drop off the left side. The older points are not lost because they are saved in the database.

The database is cool because you can export it in native format or in tabbed delimited format. If you export it in native format, you can import it back and review a previous ping session in the graph later. You can also do two reports. The first gives a list of all dropped packets. The second is a list of all packets with a travel time longer than what you specify -- this shows a list of slow packets.
