Hands-on Workshops, Serverless Architecture and Webpack For the second time in a row, we decided to participate in the Nuremberg Web Week and to share our knowledge about modern web applications with the local developer scene. This event is a meeting point for tech enthusiasts in the Nuremberg region. Each year it assembles a broad selection of conferences, presentations and workshops around digital topics.
? As a follow up to the first ever, recently released PRTG podcast (which, if you haven't listened to already, you may need to re-assess your life choices - click here immediately!), Rupert Collier, our resident UK sales manager and aspiring microphone addict, gets to work on another new project: The PRTG Interview, otherwise known as "Paessler Rupert's Thorough Grilling"!
Companies need a complete overview of their own IT infrastructure. The rapid pace of change requires the inventory overview to be frequently updated. Using Excel spreadsheets to maintain the inventory overview is limiting: inflexible, error-prone, plus data is expensive to keep up-to-date. But now the solution for inventory overview management, and many other automation problems, is here. The uniform assignment of inventory numbers, by which a device can be properly identified throughout the company, is crucial for automated processing. This includes not only the inventory label on the device itself, but also access to it via the network, the service desk ticket, the asset management data records, and the accounting software. How does automatic inventory work?

There are Many Reasons in Favor of HTTPS and None (Really) Against It
We want to monitor the temperature of our server room, and we want to do it on a budget. Maybe because we are, or maybe because we can! What do we need? Raspberry Pi Zero W: ca.?$10 Power supply for the Pi: ca.?$10 (you can even use a Powerbank to make this thing mobile!) Mirco SD Card for the Pi: ca.?$8 Case for the Pi: ca?$5 Enviro pHAT for the Pi: ca.?$16 Obviously we need PRTG Network Monitor with its HTTP Push Data Advanced Sensor
? We are very happy to announce the official pilot episode of our PRTG Podcast! It's hosted by two of our very best: Rupert Collier (the eye candy), Senior Sales Manager UK and Simon Bell (the brains), Senior Presales Engineer here at Paessler. Feel free to subscribe if you fancy listening to their shenanigans on a (possibly) regular basis. Also they won't only talk about PRTG, promise! ;)
Time and time again, we have asked ourselves the question: What's the easiest way to monitor your IT infrastructure? With PRTG Network Monitor we have established a solution, that's easy-to-use while being powerful and customizable. Now, the next logical step is to make monitoring even more accessible and provide further flexibility?enter PRTG on demand, our brand-new monitoring as a service solution, which combines the well-established monitoring technology of PRTG with the flexibility of a cloud service.
Nowadays, there are a lot of Content Delivery Network (CDN) providers available to choose from. When you're testing the performance of CDN Providers as part of your selection process, there are certain factors to be considered. Some of these factors might be beyond the control of both the provider and the customer: Generally, the network conditions vary according to the geographical areas and are beyond direct control. The conditions might vary depending on the peering relationship maturity levels operating in that geographical scope. The timing and type of the test also play a prominent role. Major traffic-generating events such as significant news announcements or headline sports events tend to affect all CDNs, regardless of the PoP architecture. However, there are some generic guidelines that can be followed. The following post aims to highlight the comprehensive framework of the CDNs, to uncover certain untold facts and also to aid you in choosing the right CDN provider for your specific situation.
PRTG already features a lot of notification options: sending email, SMS, executing commands, calling URLs, and many more. With Telegram, there is another option: Bots! You can send messages to them and they will output them in a group with all your fellow administrator colleagues.?
Almost everyone has already suffered or suffers from back pain after an exhausting work week. Stress, bad habits, excess weight, poor posture and lack of exercise are the most common factors that contribute to this. Below you can find our top ten tips for avoiding back pain.
When you open any IT news website nowadays you can read a lot about the future of IT in the cloud. The trend to move applications and data to the cloud is not just smart marketing from the big three cloud companies (Amazon, Microsoft and Google). It has many serious advantages which are especially important for businesses: cost, agility, manageability, security. So, how far has cloud acceptance come, especially for SMBs?
One of the most common (and frustrating!) questions a sysadmin needs to answer is: who is hogging all my bandwidth? The network is slow, users are complaining, and your internet connection is at 100% (again...).? You need to figure out who or what is hogging all the bandwidth, and you need to do it fast. In this article, I'll explain the different methods that are available in different situations, and how to use SNMP, RMON, flow and packet sniffing to track down the culprits.
I wouldn't be surprised if you told me you have fallen in love with SNMP. Because it is so universal in network administration. Because it is a powerful all-round talent that supplies you with nearly every kind of information you need about whatever network device. Surely you love SNMP, if you know how to set it up on your machine. And if you know what OIDs are and what you need MIBs for. And if your setup is fine, SNMP works reliably (at least it should), and you can live happily ever after.
Unlike simple work computers, server systems have at least two network cards, rather than four NICs. Likewise, many server computers have several IP addresses, which make them accessible from the network. If a computer system has multiple network addresses, this is referred to as "multihoming". Interestingly, the industry uses this conceptuality for several variations: A redundant address with multiple interfaces A server with multiple addresses on several interfaces Multiple addresses on an interface
