We at Paessler believe monitoring plays a vital part in reducing humankind's consumption of resources. Monitoring data helps our customers save resources, from optimizing their IT, OT and IoT infrastructures, to reducing energy consumption or emissions. This topic defines the "why" in "why we do our everyday business", and in July 2020, we made it our official company purpose (here is the official site for all the correlating information). This is the first article on our blog that explains how this company purpose came to life and how it influences our vision of where we at Paessler are headed.
Okay, two things are probably clear. We publish outstanding use cases on our blog every now and then – and both PRTG Network Monitor and PRTG Enterprise Monitor are, to varying degrees, made to monitor large IT environments, providing a simple way to gain visibility and control over increasingly complex infrastructures. This is part 2 of a four-part series. Are you proudly old school, don't like this newfangled blogging, and would prefer to have your use case as a proper PDF? Who could blame you? You will find the linked PDF on this use case page. iAbout Process Automation Solutions With 1400 employees in a global network consisting of more than 50 branch offices in Europe, America and Asia, ‘Process Automation Solutions’ serves customers in automotive, chemical, pharmaceutical / biotech, food & beverage, oil & gas and other industries. Its core business focuses on industrial automation, digitalization (industry 4.0) and SAP services (Gold Partner) of which the Business Unit “Digitalization” (> 220 employees) provides solutions and services in the areas of IT/OT, data analytics and historians, cloud (Azure, MS GOLD partner), MES (Manufacturing Execution Systems) and custom IT/OT applications.
While IT and OT networks might be similar, they are not the same. Monitoring OT networks using active tools as freely as in IT networks can be an issue, or even an obstacle, that might negatively impact the stability of Industrial Automation Control Systems (IACS). Here I'll discuss how passive monitoring can be deployed in an industrial IT environment, and how it can be used in conjunction with active monitoring.
Most of today's virtualization environments are powered by VMware. It just works, it is stable, reliable, scalable and powerful. Besides the proper architecture design and configuration, it is also important to keep an eye on performance, from the physical layer up to the virtual machines and hosted apps. PRTG is an all-in-one solution that can help you to monitor your physical servers, VMware, datastore, network cards, virtual machines, guest operating systems, and much more. The best practice is to start monitoring from physical servers, so you know that the underlying hardware is working properly. For this, I recommend my article, Track the health status of physical servers via iDRAC, iLO, iRMC and IMM.
…and how we empower you with our PRTG products! You probably came across this article because you want to monitor a large IT or network infrastructure. If so, I am pretty sure you are faced with several challenges. Our job at Paessler is to make this task as easy and joyful as possible for you.
Recently, my colleague Jörg, who is one of our Product Managers of PRTG, was seen in front of a camera. He talked about what challenges we are facing with our products in 2021, what we are focusing on right now, and how every PRTG user can influence what features we will develop soon!

Nobia generates profitability by combining economies of scale with attractive kitchen offerings. The Group has approximately 6,100 employees and net sales of about SEK 14 billion. The share is listed on Nasdaq, Stockholm under the ticker NOBI.
In my previous article, I talked about bandwidth monitoring between the PRTG core server and remote probe, and I mentioned the possibility of monitoring the number of sensors on each probe system and visualizing them on the map. As promised, the goal of today's article is to show you how to do it.
Since the start of the Green IT discussions about 15 years ago, the topic of data center energy efficiency has gained considerable importance. In the mid-2000s, hardly any IT managers were aware of how much energy their IT and, in particular, their data center required. Today, 85 percent of IT managers can name their annual power requirements. This change in awareness was also necessary because a data center's power consumption share is considerable. For this reason, many companies have taken measures to improve energy efficiency. On the one hand, this can mean a significant reduction of costs, but on the other hand, it also contributes to climate protection.
PRTG 21.2.67 has been available in the stable release channel since last week. With this version, we released the probe-independent Core Health (Autonomous) sensor, as well as three new experimental sensor types*: two HPE 3PAR sensors and a Beckhoff IPC System Health sensor.
Generally speaking, gateways represent links between systems that are not necessarily compatible, and thus enable communication between them. In this context, the term "system" can refer to networks, individual computers, networked devices, or even various applications. So, for example, a fax machine that receives an incoming fax and forwards it as an e-mail could be considered a gateway.
This article is part 2/2 about the protocols, gateways, and data transmission methods relevant in building state monitoring. In part 1/2 we went into details about the philosophy of building state monitoring and the various popular protocols, already telling some details about data transmission. Now let's have a look at gateways and, more importantly, the large field of data transmission methods.
In an industrial environment, several components of industrial automation are connected, and these components need to communicate with one another. Historically, this communication was done using Fieldbus, and the components were connected using serial-based communications. Data transfer was done through protocols like Modbus, PROFIBUS, CAN bus, and others.
Imagine you plan to add several network switches to your PRTG environment. But you only want to add sensors for interfaces that are connected. Until now, this required some manual effort. Since PRTG 21.1.65, you can now customize the PRTG auto-discovery with filter criteria. This allows you to precisely define in advance which sensors auto-discovery should add, and which it should not.
One of the questions we often hear is: How much bandwidth do the PRTG core server and remote probe consume in a specific time frame, and how can we visualize it on a dashboard? Well, there is no single answer here. It depends on a few factors, such as the number of remote probes, the number of sensors and channels, as well as the scanning interval. For example, 100 SNMP sensors, each with 2 channels (in & out) generate roughly 1 kbit/s plus 20 bytes/minute (due to the core "keep-alive" message). This reflects a daily load of about 11 MB a day.
