How to monitor a local web page

[donstephens]

Not a bad idea. I have an event call my script every five minutes and have actions dependent on the state of the device.

Setup some “watchdog” timer events. I do this to monitor Blue Iris. Blue Iris is setup to fire a event on HS every 10 minutes. Event resets a timer back to 0. HS monitors the timer with a second event to see if the timer value exceeds 10 minutes which indicates Blue Iris is offline or crashed and notify me.

Could have HS 4 fire a event on HS3 that indicates it is still alive using the same process.

Maybe something like:

Sub Main(ByVal Parm As Object)


Dim Host As String = "http://192.168.1.20" ' HS4 IP Address
Dim Port As Integer = 80 ' HS4 port
Dim Page As String = "/runscript.html"
Dim Ref As Integer = 123
Dim R As String = hs.GetURL(Host, Page, False, Port)

If R.ToUpper.Startswith("ERROR") Then
    hs.SetDeviceValueByRef(Ref, 0, True) ' offline
    hs.SetDeviceString(Ref, "HS4 Offline", True)
Else
    hs.SetDeviceValueByRef(Ref, 1, True) ' online
    hs.SetDeviceString(Ref, "HS4 Online", True)
End If

End Sub

Create a device and change the ref number to suit.

I'm running both HS3 and HS4 on my local LAN and I am trying to monitor HS4 from HS3 using a script.Is there some quick and dirty way to have a device represent HS4 with two states; online and offline?

Thanks
