Alerting is a basic thing and it is done kind of OK by some others. But true analytics is hard to get, we are still working on providing better reports. As an obvious plus, we provide status pages we produce by the monitoring data collected. This is for not making you depend on another service just for a status page.
Also, we are looking for ways to make WebGazer a complete monitoring and analytics platform. Plans still aren't very clear but server monitoring or client-side analytics are some things we have in mind.
