http-full-page sensor issue



Your Vote:




I'm currently using PRTG to monitor my Internet Performance for a number of websites. I'm seeing odd behavior whereby some websites will show 0ms response times (and sometimes the sensor will simply timeout.) I configured a secondary machine and configured the exact same websites and these work without issues from there.

Is there anything I can check to work out why this is happening? I've tried using; Chromium, PhantomJS and Internet Explorer and see the same results across browsers. However when I click on the device name and browse to the site it loads without issue.

I've verified my proxy details are valid and that I am able to browse to those sites normally.

An example site which shows this problem is http://www.dailymail.co.uk.

I spotted another thread which spoke about upgrading to a newer version of PRTG due to a bug in the HTTP Full Page sensor however I am running the latest available release (

Any suggestions or logs I can look at to dig into this issue? Richard

Hi Ekil,

Please enable the "Write Sensor Result to Disk" option in the sensor settings of one of the affected HTTP Full Web Page Sensors and forward us the logs in a new ticket. You can open a ticket by mailing the logs, with the explanation above, to "[email protected]". The logs are located under
