Pingotron is made for network administrators, webmasters, and Internet service providers. Pingotron allows managing devices connected to a local network (computers, printers, etc.) and communication channels in TCP/IP networks.
Basic features:
1) Custom ping time
2) Graphical and numeric representation of ping results
3) Generating lists by groups
4) Sound alarm, Email notifications, and blinking tray notification of failures
5) Logging ping history.
Pingotron is easy to use and has a handy user interface. You don't need any special knowledge to operate it. Just add to the list the network devices you want to control and set up their query parameters. Pingotron will ping these devices according to a time interval and notify you by a sound alarm, a mail message and a system tray alert if there are any problems.
For each controlled device you can turn on the query recording mode as well as specify the time span for keeping query history.
If you have a large network, you can use the "by group" display mode. This mode allows to create groups which can be controlled, for instance, to define subnets in the network.
