Let's ping your network

Ping is a command-line tool available for practically any operating system with network connectivity and is used as a test to determine if a network device is reachable. The ping command sends a request over the network to a specific device. A successful ping results in a response from the pinging computer back to the original computer. Below we will show you what ping and latency actually are, why measuring them is so important and how PRTG can save you a lot of work and time. Let's get started!

Our new MQTT sensors: video tutorials

Why DNS monitoring matters (and what PRTG can do for you)

The Domain Name System (DNS) plays a vital role in many company networks. Therefore, it is highly important that your DNS infrastructure is as stable as possible while making sure that none of your records have been compromised. With the new DNS v2 sensor, it’s now possible to not only monitor your DNS servers or public DNS servers while getting comprehensive statistics on them. It’s also possible to monitor your records that are hosted on them.

Introducing the new MQTT sensors for PRTG

Message Queuing Telemetry Transport (MQTT) is a simple lightweight protocol for transmitting data between machines. It has become one of the most important protocols in the internet of things (IoT) and now plays a major role for many companies. However, this protocol has already existed since 1999 and was developed by IBM. In 2014, it was approved as a standard by the Organization for the Advancement of Structured Information Standard (OASIS).

Government 3.0: using monitoring for next-generation government IT

There’s a term called e-government and it basically describes the use of technical resources to provide public services to citizens in a region or a whole country. In principle, the term covers all mutual relationships: It consists of the digital interactions between a citizen and the government, between a central government and government agencies or regional institutions, between a government and its citizens, between a government and its employees, and finally between government and businesses. E-government and Government 2.0 are sometimes used interchangeably, with Gartner defining the latter term as having the following characteristics; It is citizen- and employer-driven, it keeps evolving and is transformational, it requires a blend of planning and nurturing, it needs pattern-based strategy capabilities and finally calls for a new management style. In the meantime, however, areas such as big data, Internet of Things, administrative and business process management, blockchain and sophisticated monitoring are all driving public sector innovation, creating improvements in service delivery, resource management, and decision making. This transformation is often referred to as Government 3.0. Let's take a look at how monitoring enhances the technical possibilities of government IT in the 2020s.

Monitoring educational IT infrastructures with PRTG

For years there was a strong trend for schools and universities to deliver more and more content in virtual format, making learning and studying independent from time and place. With the coronavirus pandemic, this process has been accelerated to the speed of light. Within one day pupils and students had to stay at home; schools and universities became 100% virtual.

How to quickly monitor the latency of your network with PRTG

Latency is a very crucial key element that contributes to the speed of any network. The term refers to a measurement of the time it takes for a data packet to travel between two points. This is often called "latency" or “round-trip time,” and a low latency network connection is one that generally experiences small delay times – a high latency connection generally suffers from long delays. Not keeping latency spikes to a minimum will endanger the reliability of a whole network. When latency is too high, problems with VoIP and video conferences are likely to arise; furthermore, transmission errors can prevent images from loading. So it's clear that latency issues might push the capacities of any IT department to the limit, present challenges for entire business strategies and can become a serious concern.

Monitoring Stormshield Network Security (SNS) with PRTG

Network communication is presented in millions or even billions of incoming and outgoing network packets that are continuously being transmitted in the network. Integrating a powerful firewall with advanced functionalities that can do deep packet inspection and control what traffic should be allowed or denied is very important. There are different ways to do it, and one of them is by using Next-Gen UTM firewalls. Thanks to Stormshield Network Security (SNS), we can anticipate attacks and protect digital infrastructure from potential cybersecurity attacks. Stormshield Network Security solutions are built on the concept of Multi-Layer Collaborative Security. This holistic approach, based on active collaboration between the security engines of Stormshield products and solutions, represents the future of in-depth IT systems protection.

3 Ways you can use PRTG to monitor Industrial IT

Recently, I wrote about monitoring industrial IT convergence, where the worlds of classic Information Technology (IT), Operational Technology (OT) and Industrial Internet of Things (IIoT) are merging together. The whole point of the article was the importance of having a complete overview of everything in one place. Now, I want to go into a few examples of just what bringing IT, OT and the IIoT together might look like with PRTG Network Monitor. 

Some news about PRTG Network Monitor version 20.3.60

The new version contains 163 resolved issues, several security improvements, more options and improvements for SMS delivery and Amazon SNS notifications, a significantly revamped display of Paessler PRTG Enterprise Monitor license information, another significant update for the Japanese language file and many other neat enhancements for various sensors and the PRTG server.

Why CPU monitoring matters (and what PRTG can do for you)

The CPU is probably the most important component of any device in your network. And that is "probably" as in probably the earth is spherical. CPU obviously has the potential to affect network performance; not only somehow, but in some cases very seriously. CPU monitoring is the difference between network stability and performance deterioration. Having no powerful and dependable way to monitor the CPU makes the life of every sysadmin quite difficult.

Environmental and city monitoring in Coburg

Coburg is a small picturesque town in the Bavarian administrative district of Upper Franconia*, with just over 40,000 inhabitants and a population density of 854 inhabitants per km². The town is situated between the southern foothills of the Thuringian Forest, the Lange Berge and the Main valley – and when you look over Coburg's old town you see almost as much green space as houses. In short, when you think of a futuristic urban project in the context of Environmental Monitoring or Smart Cities, you are inclined not to think of a small and local town like Coburg. And therein lies already the first mistake. As we at Paessler have learned, it is precisely the decision makers of smaller towns and communities who are happy to learn about technical possibilities and innovations, because they honestly care about the well-being of their inhabitants. And the second mistake is that the term "Smart City" has unfortunately become far too vague (in fact, it has almost become an empty filler word in the tech industry) to describe what we at Paessler have already implemented together with strong partners and will continue to implement in the future. i* Wait, what? 😵 Germany is a small country, but we want to have some states too, ok? So we divide everything into even smaller units. Let me break it down for you: Bavaria is a southern, rather rural state in Germany; a government district is the next lower level. Upper Franconia is in the northern part of Bavaria and this is not the part of Bavaria where you would expect to see many Lederhosen. You can put some on, but that makes you look like an embarrassing tourist.
