Virtualization is a comprehensive subject and it doesn’t only relate to hardware virtualization, but also application virtualization, network virtualization, storage virtualization, and more. The focus of today’s article is about hardware virtualization powered by Microsoft, known as Hyper-V. The first release of the Hyper-V Server took place in Windows Server 2008 and it still exists in Windows Server 2019. Besides that, Microsoft also provides a Hyper-V Core Server that is available since the release of Windows Server 2008 and Hyper-V that comes integrated into Windows 8, 8.1 and Windows 10 Pro, Enterprise and Education editions.
Those of you who are familiar with PRTG Network Monitor know that it’s great for monitoring CCTV systems. We’ve published articles and “How To” guides on the subject, and we’re technology partners with leading camera manufacturers such as Axis.
SQL performance is measured by how efficiently and quickly SQL queries can perform the required function. It can be assessed by the time it takes to complete the operation and whether the output of the operation matches the expected requirements. Ongoing evaluation of SQL server performance helps to minimize response times and maximize throughput, which results in optimal performance. You need to analyze the application requirements, understand the physical structure of the data, and assess database usage. There are always various ways to improve SQL performance!
Convergence is something that almost all technological areas are facing, and industrial IT is no exception. And while factory floors and production lines are scrambling to meet the new challenges brought about by convergence, there is another aspect they must consider, too: how to monitor it all. But before we get to the monitoring aspect, we first should consider just what this convergence means for industrial IT.
A quick look at the calendar tells me that it's June 10, 2020. 90% of my colleagues (including myself) continue to work remotely from our homes. This is also reflected in the release 20.2.59 of PRTG Network Monitor, which was developed entirely at home - thanks to the advantages of agile, location-independent software development.

Before we go into depth on the differences between Simple Network Management Protocol (SNMP) traps and informs, we must first have a solid understanding of what a trap is.
Modbus is a communications protocol that has been in use since the 70s, and has become standard for connecting electronic industrial devices. Modbus RTU and Modbus ASCII are used for serial communication, while Modbus TCP is used for devices connected to a TCP/IP network. For IT professionals in a factory setting, who are maintaining traditional network elements and industry-specific infrastructure, Modbus TCP devices often contain important information needed for monitoring the entire infrastructure. Because it would be good to get this information into PRTG, we are currently working on a Modbus TCP sensor. But we’d love to get your feedback on your use cases and requirements, and what features you want from Modbus TCP sensor.
More and more data is being created worldwide every year. While 33 zettabytes of data were generated in 2018, forecasts predict that about 163 zettabytes will be generated in 2025. 20 percent of this will be critical for our everyday life and another 10 percent will be hypercritical, meaning necessary for the continuity of daily life. By 2025, every person in the world with Internet access will be interacting with networked devices on average 4,800 times a day - equivalent to one interaction every 18 seconds. This is mainly due to the rapid development of embedded systems and the Internet of Things (IOT).
If you're a system administrator, you've probably had a lot to do with Zoom lately. In fact, in no time at all, the word "Zoom" has become a verb—as in, "Let's zoom about this tomorrow".
Anyone who is in charge of a company's IT infrastructure has to deal with many different topics. In addition to projects, the main focus is on the smooth operation of the network. A disruption not only annoys the employees but can also have financial consequences for the company.
I'm a bit late in introducing you to the most interesting features of PRTG version 20.2.58. The release has been available for download in the stable channel since the end of April, and you probably already have it up and running. The reason for my delayed reporting is - apart from the fact that I had some vacation time in between - that we are busy working on version 20.2.59. This one contains new sensors and I can hardly wait for the release date.
Digital transformation is bringing equipment like CCTV devices into our networks. If this intricate network of devices and systems goes down, major problems could occur. A monitoring solution like PRTG Network Monitor can help to prevent downtime and give IT teams, as well as the security or facility maintenance teams, peace of mind.
What was once considered a buzz word just a few years ago has now become a dominant force in data centers around the world. Hyper convergence or Hyper-Converged Infrastructure (HCI) is the next evolution in abstraction within server infrastructure.
Do you use Amazon Web Services (AWS) for anything, anything at all really? If so, you’ve likely had a bill or two be much more costly than expected. Or maybe you’ve just paid them without actually knowing if they were way too expensive! It’s almost like they want you to overspend.
