Network Trace

Sensible website monitoring not only tells you that something goes wrong with your site, but also helps you in identifying the problem.
In case one of your transaction sensors fails, we provide you with a log of the complete HTTP traffic (i.e. whole browser session) that took place up until the error occurred. Using so called HAR files, you get the full picture of how the communication between your site and a user's browser looks like *from the browser's perspective*.

Visually, AlertFox makes use of Jan Odvarkos "HAR viewer", which has three main features:

• Summarized statistics about the kind of traffic (DNS, connect, send, receive, etc.), the kind of content that is served (HTML, JavaScript, Images, etc.) and about the HTML bodies/headers. Hovering your mouse pointer over one of the entries gives you the total numbers:
  
• A waterfall timeline of all parts of the HTTP conversation neatly displaying all timing information as well as e.g. 404 errors on a website's elements:
  
• Every single HTTP request can be drilled down to its content and the time it took to be completed:
