Network Logger Pro is an active network-testing tool for documenting outages of both your Internet connection and Web sites. It also produces charts and logs of URL speeds over long periods of time. You can export network performance graphs as PDFs and quickly show tech support what you are experiencing in a way that enables them to understand what's going on at a glance. Everyone we know who has shown Network Logger output to their service provider has had their problems solved immediately.
An optional speech synthesis feature announces when your Internet connection goes down and up which can be handy when you are working on your network in another room and saves you from walking back and forth to check your network status.
