Monitor websites: FAQ


What is website monitoring?

Web monitoring is the process of observing and testing the performance, availability, and functionality of a website or web application. It involves continuously checking various metrics such as uptime, response time, and user experience to ensure the site operates smoothly and meets performance goals. This proactive approach, usually with web monitoring tools like PRTG, helps identify issues promptly, minimizing downtime and ensuring a positive user experience.

Why should I monitor my websites?

Monitoring your website with online monitoring tools such as PRTG is crucial for several reasons.

  • First, it helps ensure that your website is available and accessible to users at all times, minimizing downtime and potential revenue loss.
  • Second, monitoring allows you to identify and address performance issues promptly, maintaining a positive user experience and preserving your brand reputation.
  • Additionally, monitoring helps you track key metrics such as website traffic, load times, and user interactions, providing valuable insights for optimizing your site's performance and meeting business goals.

How can I check if the login authentication for a web page works?

To monitor if login attempts to a web page with a specific username and password combination are successful, you can use the HTTP Advanced sensor. If the website of which you want to check login credentials uses POST data to log in to the internal area, you have to find out the needed POST data for the login and provide it with the correct syntax in the settings of the sensor.

Furthermore, you have to find the response of the login form for unsuccessful login attempts. The HTTP Advanced sensor can check this answer for defined keywords and show a warning or down status if keywords are found that indicate a failed login.

Can PRTG do more than monitoring websites?

Yes. PRTG can monitor your entire IT infrastructure including network traffic, applications, bandwidth, cloud services, virtual environments, network security, web services, and much more.

Find some more examples here:

  • Router monitoring: PRTG can also monitor your routers. In the event of error messages, high bandwidth usage, or suspicious traffic, the notification system of PRTG automatically sounds the alarm.
  • Port monitoring: PRTG helps you prevent port connection issues by querying port status, monitoring connections using UPD and TCP protocols, and checking bandwidth and traffic via SNMP, flow protocols, and packet sniffing.
  • Memory monitoring: Never run out of RAM again with PRTG that scans your Windows, Linux, and Unix systems and alerts you to any issues with memory usage.
  • Firewall monitoring: Ensure the security of your network by monitoring all traffic, staying informed on firewall status, and getting automatic alerts of malfunctions.
  • Server monitoring: PRTG monitors mail servers, web servers, database servers – and much more.

What is a sensor in PRTG?

In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, for example the traffic of a switch port, the CPU load of a server, or the free space on a disk drive.

On average, you need about 5-10 sensors per device or one sensor per switch port.
