Why does web server performance matter?

The company website is the face of your business. It must not only look good and be easy to use, but also be available at all times – especially if services and products are offered via the homepage. In fact, the performance and availability of its web server are vital to your company’s success. If the website takes too long to load or is unavailable, this can quickly lead to a loss in sales and unhappy customers – two things to be avoided at all costs. 


Why should you monitor the performance of your web servers?

To avoid downtime and slow-loading pages, you need to monitor the performance of your web servers. PRTG Network Monitor keeps a constant eye on these servers. What’s more, occasional load tests ensure the site doesn’t crash during spikes in traffic.

Important performance benchmarks for web servers:

  • Number of requests (per second) processed by the server
  • Response time between sending of request to the server and reception of response (latency)
  • Available bandwidth
  • Throughput (bytes per second)
  • Load time of sites running on the server

PRTG is a centralized web server monitoring tool 



 i How PRTG defines sensors

In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, e.g. the traffic of a switch port, the CPU load of a server, the free space of a disk drive. On average you need about 5-10 sensors per device or one sensor per switch port.
