http monitor web page element



Your Vote:




I would like to setup a sensor for an element within this webpage:


In the upper left is a status: "Online"

<span id="status" class="on">Online</span>

I would like to monitor that element and get an alert when it's offline and the status changes from "Oflfline" to "No Signal"

How can I setup a sensor for this?

Thanks, Paul

In general a HTTP Advanced Sensor can be used here. However in your case it seems like the site is generating the status dynamically, which cannot be monitored using the HTTP sensor. In this case you could maybe monitor the status using a custom powershell script and sensor.
