Why response time monitoring is a must



When the response time in your network increases, performance immediately begins to suffer. On the other hand, if your servers, websites, and applications react quickly over long periods of time, then this is a good basis for a stable network. Low response times are important for keeping coworkers and customers happy.

PRTG monitors continuously, allowing you to keep a constant eye on the response times in your network. If a problem arises, you can immediately take action to sniff out the cause – often before a disruption is detected by your coworkers.

A rise in latency may also mean it’s time to upgrade the network.


Your response times are too high? Find out why with PRTG


Any number of things can cause response times to rise. However, discovering what is responsible for a drop in performance is often like searching for a needle in a haystack. PRTG not only monitors response times, but also all kinds of network components and performance data. On the PRTG dashboard, you’ll immediately see if the CPU load of your servers is too high or if bandwidth bottlenecks are disrupting your network. In many cases, response times improve automatically once these underlying problems are fixed.


Keep a constant eye on your network
– even while on the go

PRTG can be started within minutes and it's compatible with many mobile devices.


PRTG comes with all the features you need, plus more your IT infrastructure won't want to live without.

Response time monitoring: 3 scenarios

Response times are a key aspect of many network components and services. An all-in-one
monitoring tool, PRTG provides you with a detailed view of the performance data of your entire
network. PRTG lets you define your own threshold values for each network component. If these
values are exceeded, you’ll immediately be alerted by email, SMS, or push notification.



The response time of your website is vital to ensure its pages load quickly.

PRTG monitors the response times of each page from various locations around the world and displays these times chronologically in a chart.


The performance of many applications and websites is dependent upon the performance of their underlying databases. Delays in the queries of these databases can cause the performance of all your systems to suffer.
With PRTG, you'll monitor the performance of specific queries and receive information on:

  • the amount of time needed to execute the entire database query, including the establishment and termination of the connection
  • the amount of time needed to run the query

PRTG comes with native sensors for all the most popular database systems, including Oracle SQL, Microsoft SQL, MySQL, and PostgreSQL


Excessive CPU loads, insufficient memory, and improperly distributed resources can have a negative impact on the response times of your virtual and physical servers, and thus affect the response times of your applications.
PRTG keeps an eye on all the important performance data coming from your servers. You can, for example, continually measure the transmission speed of the servers in your network, and even examine this value over longer periods of time.

Response time measurement with PRTG

The following two sensors are ideal for measuring response times:

  • Cloud Ping v2 sensor measures the response time of a user-defined server that is pinged from various different locations
  • HTTP Advanced sensor measures the load time of a website and breaks down the data according to time to first byte (TTFB) and total time


 i What is a sensor?

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.

3 ways to optimize response times

Eliminate bottlenecks

The good news is your company is growing. The bad news is that your servers are often overloaded, causing the performance of applications to dip dramatically. When response times sink below a critical level, you can count on the comprehensive network monitoring of PRTG to find out exactly where the bottleneck lies. PRTG helps you determine where upgrades are necessary, allowing you to remove bottlenecks in a timely and cost-efficient manner.

Implement CDNs

If you work for an international company, then your website is accessed by customers all over the world. As a consequence, it must perform well regardless of the location. The Cloud Ping Sensor immediately sounds the alarm if the response time of your website rises.

One easy way to improve the load times of your website is via the use of content delivery networks (CDNs).

Optimize disk performance

Slow read and write speeds on storage devices such as hard disks are often responsible for high response times. PRTG not only monitors the speed, but also the capacity of both physical and virtual drives. As a result, you can upgrade your storage devices in a more efficient manner.


Why PRTG is the ultimate
response time monitoring tool

Intuitive user interface

PRTG not only lets you keep a constant eye on your network, but it does so in a way that couldn’t be any easier for the user. This is confirmed time and again by independent software tests.

Custom dashboards

PRTG comes with customizable dashboards that provide an overview of response times and the other key performance indicators of your network. A quick glance is all it takes to see if everything is OK.

Detailed statistics

PRTG measures the response time of your websites, servers, databases, and applications over long periods of time and displays these values in easy-to-read charts. You’ll immediately see if load peaks occur in cycles and can quickly tell if an upgrade is required.

Prompt alerts

With PRTG, you can assign a threshold value to each and every monitoring point. If this value falls short or is exceeded, you’ll immediately receive an email, SMS, or push notification. Most of the time, you can fix errors before they are noticed by your coworkers. Other times, you’ll stop the problem in its tracks. As a result, you'll keep potential damage to a minimum.
