The Case for Converged Application & Infrastructure Performance Monitoring
Read this white paper and learn how you can combine and correlate performance insights from the application (code, SQL, logs) and the underlying hardware infrastructure (server, network, virtualization, storage, etc.)

One of the toughest problems facing enterprise IT teams today is troubleshooting slow applications. When a user complains of slowness in application access, all hell breaks loose, and the blame game begins: app owners, developers and IT ops teams enter into endless war room sessions to figure out what went wrong and where. Have you also been in this situation before?

Read this white paper by Larry Dragich, and learn how you can combine and correlate performance insights from the application (code, SQL, logs) and the underlying hardware infrastructure (server, network, virtualization, storage, etc.) in order to:

  • Proactively detect user experience issues before your customers are impacted
  • Trace business transactions and isolate the cause of application slowness
  • Get code-level visibility to identify inefficient application code and slow database queries
  • Automatically map application dependencies within the infrastructure to pinpoint the root cause of the problem
Achieve centralized visibility of all your applications and infrastructure and easily diagnose the root cause of performance slowdowns.
Gartner Market Guide for IT Infrastructure Monitoring Tools
With the onset of more modular and cloud-centric architectures, many organizations with disparate monitoring tools are reassessing their monitoring landscape. According to Gartner, hybrid IT (especially with IaaS subscription) enterprises must adopt more holistic IT infrastructure monitoring tools (ITIM) to gain visibility into their IT landscapes.

vSphere Troubleshooting Guide
Troubleshooting complex virtualization technology is something all VMware users will have to face at some point. It requires an understanding of how various components fit together and finding a place to start is not easy. Thankfully, VMware vExpert Ryan Birk is here to help with this eBook preparing you for any problems you may encounter along the way.

This eBook explains how to identify problems with vSphere and how to solve them. Before we begin, we need to start off with an introduction to a few things that will make life easier. We’ll start with a troubleshooting methodology and how to gather logs. After that, we’ll break this eBook into the following sections: Installation, Virtual Machines, Networking, Storage, vCenter/ESXi and Clustering.

ESXi and vSphere problems arise from many different places, but they generally fall into one of these categories: Hardware issues, Resource contention, Network attacks, Software bugs, and Configuration problems.

A typical troubleshooting process contains several tasks: 1. Define the problem and gather information. 2. Identify what is causing the problem. 3. Fix the problem, implement a fix.

One of the first things you should try to do when experiencing a problem with a host, is try to reproduce the issue. If you can find a way to reproduce it, you have a great way to validate that the issue is resolved when you do fix it. It can be helpful as well to take a benchmark of your systems before they are implemented into a production environment. If you know HOW they should be running, it’s easier to pinpoint a problem.

You should decide if it’s best to work from a “Top Down” or “Bottom Up” approach to determine the root cause. Guest OS Level issues typically cause a large amount of problems. Let’s face it, some of the applications we use are not perfect. They get the job done but they utilize a lot of memory doing it.

In terms of virtual machine level issues, is it possible that you could have a limit or share value that’s misconfigured? At the ESXi Host Level, you could need additional resources. It’s hard to believe sometimes, but you might need another host to help with load!

Once you have identified the root cause, you should assess the impact of the problem on your day to day operations. When and what type of fix should you implement? A short-term one or a long-term solution? Assess the impact of your solution on daily operations. Short-term solution: Implement a quick workaround. Long-term solution: Reconfiguration of a virtual machine or host.

Now that the basics have been covered, download the eBook to discover how to put this theory into practice!

Mastering vSphere – Best Practices, Optimizing Configurations & More
Do you regularly work with vSphere? If so, this free eBook is for you. Learn how to leverage best practices for the most popular features contained within the vSphere platform and boost your productivity using tips and tricks learnt direct from an experienced VMware trainer and highly qualified professional. In this eBook, vExpert Ryan Birk shows you how to master: Advanced Deployment Scenarios using Auto-Deploy Shared Storage Performance Monitoring and Troubleshooting Host Network configurati

If you’re here to gather some of the best practices surrounding vSphere, you’ve come to the right place! Mastering vSphere: Best Practices, Optimizing Configurations & More, the free eBook authored by me, Ryan Birk, is the product of many years working with vSphere as well as teaching others in a professional capacity. In my extensive career as a VMware consultant and teacher (I’m a VMware Certified Instructor) I have worked with people of all competence levels and been asked hundreds - if not thousands - of questions on vSphere. I was approached to write this eBook to put that experience to use to help people currently working with vSphere step up their game and reach that next level. As such, this eBook assumes readers already have a basic understanding of vSphere and will cover the best practices for four key aspects of any vSphere environment.

The best practices covered here will focus largely on management and configuration solutions so should remain relevant for quite some time. However, with that said, things are constantly changing in IT, so I would always recommend obtaining the most up-to-date information from VMware KBs and official documentation especially regarding specific versions of tools and software updates. This eBook is divided into several sections, and although I would advise reading the whole eBook as most elements relate to others, you might want to just focus on a certain area you’re having trouble with. If so, jump to the section you want read about.

Before we begin, I want to note that in a VMware environment, it’s always best to try to keep things simple. Far too often I have seen environments be thrown off the tracks by trying to do too much at once. I try to live by the mentality of “keeping your environment boring” – in other words, keeping your host configurations the same, storage configurations the same and network configurations the same. I don’t mean duplicate IP addresses, but the hosts need identical port groups, access to the same storage networks, etc. Consistency is the name of the game and is key to solving unexpected problems down the line. Furthermore, it enables smooth scalability - when you move from a single host configuration to a cluster configuration, having the same configurations will make live migrations and high availability far easier to configure without having to significantly re-work the entire infrastructure. Now the scene has been set, let’s get started!

How to Get the Most Out of Windows Admin Center
Windows Admin Center is the future of Windows and Windows Server management. Are you using it to its full potential? In this free eBook, Microsoft Cloud and Datacenter Management MVP, Eric Siron, has put together a 70+ page guide on what Windows Admin Center brings to the table, how to get started, and how to squeeze as much value out of this incredible free management tool from Microsoft. This eBook covers: - Installation - Getting Started - Full UI Analysis - Security - Managing Extensions

Each version of Windows and Windows Server showcases new technologies. The advent of PowerShell marked a substantial step forward in managing those features. However, the built-in graphical Windows management tools have largely stagnated - the same basic Microsoft Management Console (MMC) interfaces had remained since Windows Server 2000. Microsoft tried out multiple overhauls over the years to the built-in Server Manager console but gained little traction. Until Windows Admin Center.

WHAT IS WINDOWS ADMIN CENTER?
Windows Admin Center (WAC) represents a modern turn in Windows and Windows Server system management. From its home page, you establish a list of the networked Windows and Windows Server computers to manage. From there, you can connect to an individual system to control components such as hardware drivers. You can also use it to manage Windows roles, such as Hyper-V.

On the front-end, Windows Admin Center is presented through a sleek HTML 5 web interface. On the back-end, it leverages PowerShell extensively to control the systems within your network. The entire package runs on a single system, so you don’t need a complicated infrastructure to support it. In fact, you can run it locally on your Windows 10 workstation if you want. If you require more resiliency, you can run Windows Admin Center as a role on a Microsoft Failover Cluster.

WHY WOULD I USE WINDOWS ADMIN CENTER?
In the modern era of Windows management, we have shifted to a greater reliance on industrial-strength tools like PowerShell and Desired State Configuration. However, we still have servers that require individualized attention and infrequently utilized resources. WAC gives you a one-stop hub for dropping in on any system at any time and work with almost any of its facets.

PowerCLI - The Aspiring Automator's Guide
Automation is awesome but don't just settle for using other people's scripts. Learn how to create your own scripts and take your vSphere automation game to the next level! Written by VMware vExpert Xavier Avrillier, this free eBook presents a use-case approach to learning how to automate tasks in vSphere environments using PowerCLI. We start by covering the basics of installation, set up, and an overview of PowerCLI terms. From there we move into scripting logic and script building with step-by

Scripting and PowerCLI are words that most people working with VMware products know pretty well and have used once or twice. Everyone knows that scripting and automation are great assests to have in your toolbox. The problem usually is that getting into scripting appears daunting to many people who feel like the learning curve is just too steep, and they usually don't know where to start. The good thing is you don't need to learn everything straight away to start working with PowerShell and PowerCLI. Once you have the basics down and have your curiosity tickled, you’ll learn what you need as you go, a lot faster than you thought you would!

ABOUT POWERCLI

Let's get to know PowerCLI a little better before we start getting our hands dirty in the command prompt. If you are reading this you probably already know what PowerCLI is about or have a vague idea of it, but it’s fine you don’t. After a while working with it, it becomes second nature, and you won't be able to imagine life without it anymore! Thanks to VMware's drive to push automation, the product's integration with all of their components has significantly improved over the years, and it has now become a critical part of their ecosystem.

WHAT IS PowerCLI?

Contrary to what many believe, PowerCLI is not in fact a stand-alone software but rather a command-line and scripting tool built on Windows PowerShell for managing and automating vSphere environments. It used to be distributed as an executable file to install on a workstation. Previously, an icon was generated that would essentially launch PowerShell and load the PowerCLI snap-ins in the session. This behavior changed back in version 6.5.1 when the executable file was removed and replaced by a suite of PowerShell modules to install from within the prompt itself. This new deployment method is preferred because these modules are now part of Microsoft’s Official PowerShell Gallery. 7 These modules provide the means to interact with the components of a VMware environment and offer more than 600 cmdlets! The below command returns a full list of VMware-Associated Cmdlets!

Office 365 and Microsoft 365 contain truly powerful applications that can significantly boost productivity in the workplace. However, there’s a lot on offer so we’ve put together a comprehensive companion guide to ensure you get the most out of your investment! This free 85-page eBook, written by Microsoft Certified Trainer Paul Schnackenburg, covers everything from basic descriptions, to installation, migration, use-cases, and best practices for all features within the Office/Microsoft 365 sui

Welcome to this free eBook on Office 365 and Microsoft 365 brought to you by Altaro Software. We’re going to show you how to get the most out of these powerful cloud packages and improve your business. This book follows an informal reference format providing an overview of the most powerful applications of each platform’s feature set in addition to links directing to supporting information and further reading if you want to dig further into a specific topic. The intended audience for this book is administrators and IT staff who are either preparing to migrate to Office/Microsoft 365 or who have already migrated and who need to get the lay of the land. If you’re a developer looking to create applications and services on top of the Microsoft 365 platform, this book is not for you. If you’re a business decision-maker, rather than a technical implementer, this book will give you a good introduction to what you can expect when your organization has been migrated to the cloud and ways you can adopt various services in Microsoft 365 to improve the efficiency of your business.

THE BASICS

We’ll cover the differences (and why one might be more appropriate for you than the other) in more detail later but to start off let’s just clarify what each software package encompasses in a nutshell. Office 365 (from now on referred to as O365) 7 is an email collaboration and a host of other services provided as a Software as a Service (SaaS) whereas Microsoft 365 (M365) is Office 365 plus Azure Active Directory Premium, Intune – cloud-based management of devices and security and Windows 10 Enterprise. Both are per user-based subscription services that require no (or very little) infrastructure deployments on-premises.

Top 10 VMware Performance Metrics That Every VMware Admin Must Monitor
How does one track the resource usage metrics for VMs and which ones are important? VMware vSphere comprises many different resource components. Knowing what these components are and how each component influences resource management decisions is key to efficiently managing VM performance. In this blog, we will discuss the top 10 metrics that every VMware administrator must continuously track.

Virtualization technology is being widely adopted thanks to the flexibility, agility, reliability and ease of administration it offers. At the same time, any IT technology – hardware or software – is only as good as its maintenance and upkeep, and VMware virtualization is no different. With physical machines, failure or poor performance of a machine affects the applications running on that machine. With virtualization, multiple virtual machines (VMs) run on the same physical host and a slowdown of the host will affect applications running on all of the VMs. Hence, performance monitoring is even more important in a virtualized infrastructure than it is in a physical infrastructure.

How does one determine what would be the right amount of resources to allocate to a VM? The answer to that question lies in tracking the resource usage of VMs over time, determining the norms of usage and then right-sizing the VMs accordingly.

But how does one track the resource usage metrics for VMs and which ones are important? VMware vSphere comprises many different resource components. Knowing what these components are and how each component influences resource management decisions is key to efficiently managing VM performance. In this blog, we will discuss the top 10 metrics that every VMware administrator must continuously track.

The SysAdmin Guide to Azure Infrastructure as a Service
If you're used to on-premises infrastructures, cloud platforms can seem daunting. But it doesn't need to be. This eBook written by the veteran IT consultant and trainer Paul Schnackenburg, covers all aspects of setting up and maintaining a high-performing Azure IaaS environment, including: • VM sizing and deployment • Migration • Storage and networking • Security and identity • Infrastructure as code and more!

The cloud computing era is well and truly upon us, and knowing how to take advantage of the benefits of this computing paradigm while maintaining security, manageability, and cost control are vital skills for any IT professional in 2020 and beyond. And its importance is only getting greater.

In this eBook, we’re going to focus on Infrastructure as a Service (IaaS) on Microsoft’s Azure platform - learning how to create VMs, size them correctly, manage storage, networking, and security, along with backup best practices. You’ll also learn how to operate groups of VMs, deploy resources based on templates, managing security and automate your infrastructure. If you currently have VMs in your own datacenter and are looking to migrate to Azure, we’ll also teach you that.

If you’re new to the cloud (or have experience with AWS/GCP but not Azure), this book will cover the basics as well as more advanced skills. Given how fast things change in the cloud, we’ll cover the why (as well as the how) so that as features and interfaces are updated, you’ll have the theoretical knowledge to effectively adapt and know how to proceed.

You’ll benefit most from this book if you actively follow along with the tutorials. We will be going through terms and definitions as we go – learning by doing has always been my preferred way of education. If you don’t have access to an Azure subscription, you can sign up for a free trial with Microsoft. This will give you 30 days 6 to use $200 USD worth of Azure resources, along with 12 months of free resources. Note that most of these “12 months” services aren’t related to IaaS VMs (apart from a few SSD based virtual disks and a small VM that you can run for 750 hours a month) so be sure to get everything covered on the IaaS side before your trial expires. There are also another 25 services that have free tiers “forever”.

Now you know what’s in store, let’s get started!
