Is it possible to parse/scrape a custom 404 page with an HTTP sensor?

Hi Peter,

You're right here, this article lists all status codes and how the PRTG sensors behave. Do I understand you correctly that you simply want to monitor for status codes? Then, this would help.

Kind regards,

Thanks for the reply, but no, we aren't monitoring for status codes. We need to scrape the text of the 404 error page, to make sure the default Tomcat error page isn't being used.

We ended up developing a Powershell script to handle this.

try { Invoke-WebRequest https://www.contoso.com/123 } catch { $result = $_.Exception.Response.GetResponseStream() $reader = New-Object System.IO.StreamReader($result) $reader.BaseStream.Position = 0 $reader.DiscardBufferedData() $responseBody = $reader.ReadToEnd(); $responseBody.Contains(“Tomcat”) }

Hi Peter,

I'm afraid this is indeed only possible using a powershell script and custom sensor. The default HTTP sensors cannot be used here. Thank you for sharing your script here!
