News From PaesslerMastering JMX metrics: The key to effective Java application monitoringEver had a Java application mysteriously slow to a crawl or crash without warning? If you've spent hours digging through log files trying to figure out what went wrong, you're not alone. The JVM is like a black box sometimes - things happen inside it that aren't immediately visible from the outside. You might see the symptoms (slow response times, high CPU usage), but finding the root cause can feel like searching for a needle in a digital haystack. That's where JMX metrics come in. Java Management Extensions (JMX) provide a standardized way to monitor and manage your Java applications, giving you visibility into that black box. But despite being built into the JDK since version 5, JMX remains surprisingly underutilized by many teams who could benefit from the wealth of runtime information it provides. Mastering Amazon CloudWatch S3 metrics: The complete guideEver had to troubleshoot a mysterious S3 performance issue right before a critical deployment? Or explain to your boss why the AWS bill suddenly doubled? If you're nodding along, you're not alone. Amazon S3 is deceptively simple; easy to set up, but challenging to optimize and monitor effectively. The key to getting control of your S3 infrastructure lies in understanding and leveraging CloudWatch metrics. As an S3 administrator, you're already juggling storage classes, lifecycle policies, and permissions. Adding metrics monitoring might seem like another task on your never-ending to-do list. But without proper visibility into your buckets, you're essentially flying blind, hoping nothing breaks while costs quietly spiral upward. Monitoring VMware vSphere Performance: A Guide to Virtual Infrastructure OptimizationPerformance problems in a virtualized environment can snowball quickly. One virtual machine running slowly is one thing, but soon an entire application stack may begin to crawl as problems cascade through all of the virtual resources it touches. You find yourself looking through reams of metrics trying to figure out where things have gone awry. You pore over vCenter Server performance graphs in the middle of the night wondering why the whole virtual infrastructure is grinding to a halt. Serverless computing: Freeing developers from infrastructure headachesEver found yourself neck-deep in server configurations when you should be writing code? Or maybe you've been jolted awake at 3 AM by alerts about a misbehaving virtual machine? Welcome to the club that nobody wanted to join: the "infrastructure management takes over my life" club. It's that part-time job nobody signs up for but somehow comes bundled with your developer or IT role. But what if there was a way to shift your focus almost entirely to writing code while someone else handles the server provisioning, scaling, and maintenance? That's the promise of serverless computing. An approach that, despite its somewhat misleading name, is changing how we build and deploy applications to the cloud. How to see all IP addresses on network: A guide for IT professionalsIt's one of those moments when you have to find a particular device on your network but have no idea what IP address to use to reach it. Or maybe you are troubleshooting connectivity issues and want to see what devices are online (and which are not). Or just want to know who is connected to your home Wi-Fi?for whatever reason, being able to see all IP addresses on a network is a useful skill to have in IT (and even for home users). IP addresses are the "mailing addresses" of the internet. Packets need to know where to go or they'll just get lost. But, unlike snail-mail envelopes, IP addresses are not usually visible "outside" of devices, making them effectively invisible until you know how to uncover them. In this guide, I'll cover everything you need to know about finding all IP addresses on a network. From command line methods to advanced network scanning tools, I'll show you step-by-step techniques to uncover all IP addresses in any situation - whether you are working with Windows, macOS, Linux, or even larger enterprise networks. VXLAN vs VLAN: Network segmentation for the modern data centerRemember apartment living? The person whose floor somehow got home-delivered pizza at 2 AM? Or when a neighbor's attempt to create healthy dishes somehow ended up teleporting into your unit? Apartment buildings are good because they allow physical partitions. Walls, floor separation, and front doors limit how much your neighbors can intrude on you. Networks need that separation too. Broadcast storms, security, and performance ? all of them would drive large networks insane without network segmentation. This is where VLANs (Virtual Local Area Networks) come in. Enter VXLAN (Virtual Extensible LAN). The newcomer in network segmentation is quickly rising in popularity. It has several benefits over traditional VLANs. But is it always better? When should you use which? And what is the best way to monitor your network segmentation? Let's explore both technologies and find answers. Network protocols list: The language of the digital world explainedAs a kid, did you and your best friends invent a secret language only you understood? You might have placed random syllables between words or used bizarre code phrases your other classmates could not understand. This secret language allowed you and your friends to hold conversations and still keep your parents in the dark. ALB vs ELB: Which AWS load balancer is right for your workloadsThe good old days. One box to rule them all. One box to find them. One box to bring all your visitors and in the darkness bind them. Back when your entire website was served from one server, everything was simple. Fast-forward to modern web applications that typically run on more than one EC2 instance, container, or Lambda function. This architectural complexity creates one big question: How can you evenly distribute incoming traffic across all these resources? Enter the world of AWS load balancers. These highly available servers direct the client requests to the most healthy compute resource that can serve the request. Types and features of common network servicesIf you've ever looked at a network diagram and wondered what all those boxes and arrows do, you're in the right place. Network services are the quiet workhorses of our connected world. They're the ones making sure everything works while we all focus on the result: connectivity. Don't be fooled by their humble status, though. A good understanding of network services is no longer just for the IT department. With businesses becoming more and more reliant on networks running smoothly, knowing how they tick is a great way to avoid a lot of future headaches when things go wrong. In this article, we'll discuss the different types of network services, explain how they work, show where they can be found, and even highlight common problems you can run into with each. You'll also find out how PRTG Network Monitor helps you avoid many of the issues before they happen. Azure metrics: Turning cloud complexity into monitoring magic with PRTGDo you remember the good old days when you could march right up to the server and give it a good whack on the side? You know, the old ones-two fingers-across-the-top. It didn't work a lot of the time, but when it did, it worked like magic. Log forwarding: Taming the chaos of system logs with PRTG Data HubLogs are like glitter. ? You can never have too much of them, and once you do have them, there's just no getting rid of them. Every device, app, and service in your IT environment is constantly shouting over itself, "Hey! Look at me! I'm doing something! And it would really help if you could see everything I was doing all at once in agonizing detail!" Sooner or later, you're going to need a strategy to cope with this incessant deluge of noise, and that's where log forwarding with PRTG Data Hub comes into play. Think Synology is just NAS? Here?s how to monitor their cameras, too!Many people know Synology for its great NAS products, but did you know that they also produce cameras? That?s right! In addition to NAS systems, Synology manufactures routers, wireless access points (WAPs), and cameras. AWS cloud monitoring: How to weather the storm with PRTGAh, the cloud. That wondrous digital Nirvana where your data frolics happily on someone else's computers while you sacrifice goats to the technology gods in the hopes that everything keeps working as intended. If you're a sysadmin type blessed (or more likely cursed) with the task of managing AWS resources you've no doubt experienced the white-knuckle thrill that comes when your boss innocently asks, "Hey, is everything up in the cloud okay?" and you somehow manage to blurt out the affirmative while simultaneously opening five separate monitoring windows to ensure that you're not being dishonest. Proactive monitoring: Preventing IT problems before they impact your businessLet's face it - reactive monitoring just doesn't cut it anymore. We've all been there: the frantic troubleshooting, and the painful post-mortem explaining why critical systems went down. These failures cost companies millions in downtime every year (not to mention countless IT team headaches). Network documentation that prevents chaosNetwork outages caused by preventable technical problems cost organizations an average of $5,600 per minute. Yet the vast majority of IT operations teams still depend on outdated spreadsheets and reactive troubleshooting the next time a critical system goes down. The organizations that cut downtime to a minimum experience way less network chaos than their peers struggling to tame network complexity. The magic sauce? Well, it's network documentation that flips reactive network firefighting on its head to set up your IT teams for proactive infrastructure management. |
