Paessler BlogScaling PRTG Horizontally For Large EnvironmentsIf you use PRTG, you already know that it can monitor almost everything: from switches, routers, and firewalls through to printers and workstations, there are tons of options. As a very general rule of thumb, each device in your network will need an average of ten sensors to monitor it. This depends on what is being monitored and what information you need, but it's a reliable metric to roughly calculate the number of sensors to implement in PRTG. And the number of sensors has a direct impact on how you will deploy PRTG. 5 Things I Learned While Interning as a SysadminPaessler is very open-minded when it comes to ideas that help “broaden your horizon”. One of the great opportunities we have here is to do internships in other departments to learn new skills, understand pain points and grow together as a company. Since I’m fresh out of university and felt that I lagged behind on the more practical side of anything related to IT, I got to live as a Sysadmin for two whole months. How Technology Will Change Our Lives in the Next 5 YearsAs an innovation manager, I am trying to keep pace with current tech trends and have come across a couple of exciting stories I want to share. After reading so many individual pieces of information, I am trying to see the bigger picture behind it all and what we’re aiming at. Some of these tech trends stand out, and I frequently see opinions that I think are misleading. Also, I think these changes are coming very slowly and will go almost unnoticed – we will understand how much they changed our lives only afterwards. Is It Possible to Monitor OSI Model Layer 8?You no doubt know the OSI model, and you probably work with it every day. If you're a sysadmin and don't know what I'm talking about, then... no, everyone knows what I am talking about! ?? Why MQTT Is Everywhere, and the Security Issues It FacesIn a previous article, I detailed the history of MQTT and how it came to be one of the most commonly-used protocols when it comes to the Internet of Things. I ended that article by asking several questions: Why would someone choose MQTT over HTTP as a communication protocol? And why choose MQTT over enterprise messaging systems like AMQP? As I said then, to answer those questions, it helps to first understand how MQTT works. Then I’ll discuss some of the problems it has faced in recent times. Chris Dancy at the Paessler HQ - Part 2/2What the world knows about Chris Dancy: He is the most connected human on earth.

The days with Chris were inspiring and we created 2 videos to try encapsulate his ideas. How to Monitor Meeting Rooms with PRTGDid you just receive a last-minute request for a customer call and are now frantically looking for a free meeting room?

SAP Monitoring with PRTGMany large and medium-sized companies rely on SAP as their ERP solution for business-critical areas. One reason they use SAP is for its high availability features. A system failure or a performance degradation will cause high expenditures in IT and cause work restrictions for the users and customers and using a highly available database will prevent this from happening. Company Network + Private IoT Devices = TroubleThe days of BYOD have changed the way we deal with our workplace. We now use private devices much more naturally in the workplace, perform certain work tasks using them, and are generally much more flexible. But what are the consequences if more and more employees bring more and more IoT devices to work? How to Set Up Reports in PRTG in 5 Easy StepsYour PRTG is up and running. You’ve built a flawless device tree with everything perfectly organized in accordance with your network hierarchy. You’re getting email, SMS and push notifications when things are down or problematic.But now the CIO wants regular reports about the uptime and availability of a critical application or service you provide to end users. The CIO will be sharing these reports with the rest of the executive team, so you need to keep it “high level”. Where do you start? The Silex and the Fury: New Malware Tries to Destroy IoT DevicesA new malware called Silex is targeting IoT devices. The software does not want to take the devices over, in order to use them for DDoS attacks, but rather wants them to malfunction and shut down. 8 Reasons Why Documentation Is Vital for Your IT EnvironmentIs IT documentation a source of joy, or a necessary evil? Experience shows that most companies only maintain IT documentation to comply with legal regulations. From Oil Pipelines to the IoT: A Brief History of MQTTIf it feels like the Internet of Things (IoT) has kind of gone from zero to ubiquitous hype in the space of no time at all, you're not wrong: it's only been around in its current form since the late 90s. Now I know, many might argue that there was a "smart" toaster in the 70s or a monitored coffee pot in the 80s, but the IoT as we now know it only really took shape at the turn of the century. And while it showed some potential right from the early days, it needed a few developments before it could truly become useful. One Flew over the Paessler's NestMore and more companies are paying attention to their energy consumption, but only a few generate their own energy. We are quite happy that our roof now serves as more than just rain protection. |
