Monitor URL to google.com ?!?
Hello everyone,
You can use the Monitor URL (or TCP Monitor) aiming for a server from the internet (Example google.com) ?. The intent is to verify that the company has access to internet, via monitor.
Thank you all.

James,
Could you share a screenshot of your monitor configuration, please? Here's what I think you should have:
Well, now I see that you wanted to use https, so this screenshot is not exactly what you want ...

The issue was with how I defined the host, in the host address I had actually used https://www.verizon.com/ 
And that was the results, the issues was even after I corrected it the new settings didn't seem to be picked up until I restarted the DT server itself. I attempted to restarting the collector, but that didn't help.
I add the host address wrong as https://www.verizon.com, but after correcting it and evening recreating the monitor the collector is still trying to use http://[https://www.verizon.com]/ and throwing an error. Any ideas on what might be causing the issue?
Here is the text from the log:

It seems this is some caching error, after restart of dynatrace server this was corrected.
Just an FYI for others that may want to do similar things. I covered this exact use case including alerting in one of my perf clinics. find the recoding on our youtube channel: https://www.youtube.com/watch?v=Ysh_HL8HDoA&index=11&list=PLqt2rd0eew1bmDn54E2_M2uvbhm_WxY_6

Thank you guys,
It worked, after configuring the proxy.
Regards,
Fernando.
Fernando,
Yes, you can use the URL monitor plugin to verify that access to the internet is working. Note, however, that the plugin is run on the Dynatrace Collector, and so checks connectivity from there. You could still have a problem, e.g., in other firewall zones if there was a firewall problem.

yes, you would need to set-up a host that is google.com to do this as the monitor runs against the different hosts. This could also be a good way to test that your site is currently up by setting up www.myapplication.com.
Edit: I would make sure that you are verifying some sort of content on the google homepage something like "I'm Feeling"
