Watchit can be a very valuable tool if all you do is sit by your computer and watch for it to stop responding but it is not that practical for most people going back and forth to IDF's and what not.
Two things that can be improved with Watchit.
1. Store trend data, that, similar to NPM, has a chart that shows when pings were dropping. This way if I step away and packets start dropping then pickup before get back I can see that. Also being able to set the ping interval would help a lot as well
2. Integrate with ping sweep. What I will do to check on networks is do a ping sweep of the network, it would be nice if I could right click on an address and select Watchit then have it added to the Watchit list.
Thanks
