Check URL value

[MrJohn230]

I am working in Classic dashboard. I have a gateway address (URL: abc23.com ) I want to check this value after every dashboard refresh. Either display the results of the URL and/or single value visual with green and red colors. Green is for when the URL status is set to "OK", else is "Red". 

Any ideas on how I can accomplish this task?

I created a python scrip that extracts the value into a log and then the dashboard checks the log but this doesn't seem like the best approach and not really what I want.

With which part of the task do you need help?  What have you tried so far?  Have to seen the Website Monitoring app (https://splunkbase.splunk.com/app/1493)?
