Response: Technical Specifications

Guðrún Gústafsdóttir avatar


Siteimprove Response monitors servers' HTTP-requests at a certain distance and sends to predefined URLs. The Response module monitors a website's server(s) response and if required, the content of the response. If the response time exceeds the limit defined by the customer, we will notify you immediately via e-mail and/or text message. This article is intended to outline the technical specifications in regards to Siteimprove Response.

IP Addresses and User Agents

The IP address and user-agents used by Response can be found in the article "What IP addresses are used by Siteimprove?" (login required).

Scan Type

HTTP content scanning: GET request for the HTML is sent and parsed along with positive or negative matches are evaluated. 

Server Locations

It is possible to select which monitoring servers you want to monitor your checkpoint. Monitoring servers are available worldwide.

  • Australia
  • Sâo Paulo
  • Frankfurt
  • Mumbai
  • Ireland
  • Tokyo
  • Singapore
  • Seoul
  • Northern California
  • Northern Virginia
  • Oregon

Alerts

Alerts are triggered by the following events:

  • If no response to the HTTP request within the time configured
  • The response status differs from 200 (Follow Redirect on 301 and 302 can be used as allowed set up)
  • If the content scanning is enabled and finds no positive match or the entered negative match is found
  • If a login is required and this fails

Users can be alerted via email and/or text message.

Any number of users can configured to receive alerts.

Custom Check Options

Reporting and Statistics

In addition to the alerts, Siteimprove offers daily, weekly, or monthly Response reports, showing you the collected monitoring statistics. The reports show average response time, any registered downtime, and errors found. The data allows the server to keep track of your checkpoint's responsiveness, and rush hours identify what helps to detect problems before site users find it.
