What is web service monitoring?

“Web service monitoring” refers to the monitoring of web services and the collection of valuable data regarding performance and availability.

Tools like Paessler RTG can help you measure key parameters such as connection times, load times, and overall performance.



Why do companies need web service monitoring tools?

By monitoring your web services, you can assess the performance of your websites and keep an eye on your cloud (and other) services.

Among other things, a monitoring tool can be used to perform a ping test. The ping will indicate whether or not it is possible to connect to your website. If your site is unreachable, this must be fixed at once.
After all, potential customers can only find you if you’re visible online.

Web service monitoring also helps you reduce “downtime” (i.e., prevent your servers from crashing). If your mail server is down, a monitoring tool can help you quickly uncover and fix the problem.


What are the advantages of
Paessler PRTG?



 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.

Ping und HTTP Sensoren

Ping and HTTP sensors

PRTG monitors all the most common web services. It comes with ping sensors and HTTP sensors that let you keep a constant eye on the access times of your websites (for example).

PRTG alarmiert

Alert feature

PRTG lets you set threshold values which immediately trigger an alert when exceeded. This built-in alarm is customizable and included free of charge.

REST sensoren

REST sensors

REST (Custom) sensors offer a variety of ways to check the performance of your services. In particular, they let you:    

• Monitor the availability of your REST API

• Automatically detect the content of XML and JSON files

• Analyze up to 50 parameters per sensor

• Select custom REST configuration templates

• Perform customized JSON and XML mapping


Intuitive and user-friendly

The biggest advantage of PRTG? Our web service monitoring tool is incredibly intuitive and user-friendly. Thanks to its Smart Setup and Auto Discovery tools, PRTG is extremely quick and easy to configure. What’s more, an overview tab displays all the values obtained from monitoring your REST API.

Gesamtes Netzwerk

All-in-one monitoring

PRTG doesn’t just monitor your servers – it monitors your entire network. All-in-one software, PRTG is the perfect alternative to a mishmash of complex (and error-prone) monitoring applications. PRTG is a centralized solution for monitoring your hardware, software, and traffic.


What are the benefits of cloud service monitoring?

Paessler RTG is also ideal for monitoring cloud services. Cloud service monitoring lets you check the availability and performance of your cloud services. Our Cloud HTTP v2 Sensor provides information on overall performance, while the Cloud Ping v2 Sensor monitors the ping times of services. Both sensors are compatible with all cloud providers. With the PRTG web service monitoring tool, you get a quick overview of all your services and can monitor each of your cloud strategies independently.

PRTG cloud server monitoring sensors are perfect for: 


Amazon Web Services Monitoring

Keep an eye on all your Amazon accounts. PRTG queries data from each account, then displays it in the central sensor overview.

Dropbox Monitoring

PRTG uses the Dropbox API to display the amount of free space available in the popular cloud storage service Dropbox.

Google Analytics Monitoring:

Google Analytics lets you track and analyze the traffic on your website. PRTG uses a sensor to access the Google API and collect all the most important data. Among other things, you can have unique users or views displayed on your PRTG dashboard. 

PRTG also comes with many more handy features. For additional information, visit our page on cloud monitoring.

Need a sensor that is tailored to your own specific needs? With the PRTG web service monitoring tool by Paessler, you can configure your cloud sensor to meet the needs of any situation.
