Hi there, I need some help monitoring a web page using a HTTP monitor. I simply want to know when the HTTP server is no longer accessible. My current flow is attached below (too big to paste). Thanks [ { "id": "82df664307dddebe", "type": "tab", "label": "Flow 2", …

Tell us what the problem is with that flow.

There is no problem with this flow, I want to add a flow for monitoring HTTP GET instead of PING, and output the result in the same format so I can be notified when the website is unreachable. Thanks

Yea, using the web-watch node or even HTTP-in node, it just spits out the HTTP header. Not sure how to change that to 1 or 0.

Why would you think you would?

You should switch on status code and if the msg comes out of the 200 port, it was successful. If it comes out of the 400 (or any other) it was not.
