Web Site availability Monitoring

I find the dashboard widgets for Website monitoring is rather limited. I believe when you use Add > Widget there are just two that can look at website stats (vs alerts): website status and SLA. It would be worth looking at those. You can also look at the graphs on the Website page's Graph tab and for those you want, you can use the down arrow to Add To Dashboard. These can get you graphs of items like response time, status and permanence. But I believe you need to do that for every website manually. As far as I know, you can't build a table of just individual "datapoints" for websites like you can for Resources. If you are also monitoring webservers more directly, you can try using the HTTP/HTTPS Status instead, but that is checking the server within your LAN and not from the public internet.

As for the NOC widget, as you said it shows the active alerts. But I'm not clear why you said it's not reporting current state. Alerts should reflect how it is right now (well within a few minutes) and alerts should clear if the website comes back up. It shouldn't be showing alerts that has already cleared.
