Hi,
I've recently purchased OpManager which is a comprehensive network monitoring tool that offers combined WAN, LAN, Server, Database and Application monitoring. OpManager proactively monitors and alerts through web alarms, email and even text messages to my mobile phone - I'm now sure of not getting into any serious IT infrastructure crisis. I thought OpManager will be useful for you too.
The main reasons of why I chose OpManager are because of: "..... as quoted in What were the main reasons for you selecting OpManager ....."
Take a look at the cost-effective, feature-rich software when you get a chance. For more information, you can reach the website at "http://OpManager.com"
