Generating a Support Bundle: How to Retrieve Virtual Infrastructure Logs from VMware vCenter and ESXi Servers

http://www.vmgu.ru/content_images/vmware_psod-4.png

One day, any VMware administrator may require the so-called “support bundle” which contains log-files, diagnostic information, and performance metrics. Taken together, these parameters allow troubleshooting VMware vSphere. The bundle provides VMware GSS (Global Support Services) the insight into virtualized environment configuration which allows them to resolve issues, when a client submits a support ticket with this bundle attached.

Apart from that, the bundle comes in handy, for example, while analyzing the reasons of the “pink screen of death” (PSOD) in ESXi environment and other errors.

This article discusses retrieving the support bundle for VMware vCenter servers (be it Windows or vCenter Server Appliance, vCSA) and VMware ESXi.

Before we go deeper, here’s a small note: the support bundle can bloat to 300 MB, depending on what it contains, the frequency of infrastructure configuration changes, and how long ago the last change has been made.

CLI vs. GUI for VMware Admins

CLI vs. GUI for VMware Admins

The term User Interface (UI) is used for specifying how a user interacts with a specific device, or software. CLI and GUI are two different types of possible user interfaces.

Let’s analyze those different approaches and the pro and cons of them, using the VMware vSphere environment as an example.

Why upgrade to VMware vSphere 6.5 (or why not)

VMware vSphere 6.5 is the latest version of the enterprise server virtual platform from VMware, but the new beta it’s already there for testers. Actually the next version it’s (in the beta). If you are building a new infrastructure from scratch the latest stable version is probably the best choices (for most cases); but what about if you have an old environment and you plan to upgrade it?

5 Tips to Master VMware vCenter Server Appliance

VMware vCenter server appliance is evolving with every major release of VMware vSphere Suite. The product, which manages the whole vSphere infrastructure, can be either installed on a Windows server or deployed as pre-configured virtual appliance called vCenter Server Appliance (VCSA).

Over several VCSA releases, VMware managed to make this product equal to the Windows-based one, and it pushes the development even further so now the Linux based product has more features than the vCenter server installed on Windows.

However, many VMware admins are also Microsoft guys and like the graphical user interface to work with. That’s why today we’ll have a look at 5 Tips to manage this appliance. We won’t go into the configuration steps within this post as this has been documented many times.

5 useful tips to work with VMware vCenter Server Appliance 6.5

Nowadays, many VMware vSphere administrators manage their virtual infrastructures with VMware vCenter Server Appliance 6.5 (vCSA). This solution currently is a full-fledged alternative to the VMware vCenter for Windows which becomes a thing of the past.

For ones who use vCSA not that long, this post provides several procedures which simplify solutions’ daily use. Let’s have a look at how they may come in handy.

VMware vSphere APIs for I/O Filtering (VAIO) – how does it work?

VMware has recently released VMware vSphere APIs for I/O Filtering (VAIO), a handy document that highlights the VAIO I/O Filtering technology operational principles. Here, we shed light on them briefly and discuss how VAIO can be implemented in a production environment.

VAIO is a technology and an API providing the direct access to the virtual machines’ guest OS I/O Stream. VAIO is already employed in partner products for maintaining various tasks (i.e., caching write-back and write-through). VAIO is based on the Storage Policy Based Management framework, dedicated to managing virtual machines storages and set the storage rules.

Getting started with PowerShell and VMware vSphere

Since some time, VMware provides PowerCLI which is a set of modules for VMware vSphere. Except if you were in a cave last 10 years, you should know that PowerShell is a powerful scripting language. Initially, PowerShell enabled to manage only Windows Workstation or Server but since sometimes, a lot of vendors make their own modules to manage their solutions (such as Veeam, VMware and so on). Moreover, PowerShell is available on Linux.

For my job, I always use PowerShell. I’m a lazy guy, and if I have to make something two times, I make a script. This is the same thing for VMware vSphere. In this topic, we’ll see how to connect to vCenter and some commands to start.

vSphere Upgrade Options

When it comes time for your vSphere upgrade there are many different approaches to how you perform the upgrades on your ESXi hosts.   An administrator who looks after a small cluster may update one way, whereas an administrator who looks after an enterprise with 1000s of hosts may opt to go another.  Also, depending on how your environment is deployed you might want to choose one method over another.  Factors such as a whether or not your hosts are managed by a vCenter server, whether or not they are members of a cluster – these things all impact the methods in which you chose to update to the latest version of ESXi.  Certainly, some methods are much more simplistic than others to perform, some offer more advantages when upgrading at scale, and some are more prone to user error – let’s take a look at each method of upgrading our hosts below and discuss the benefits and drawbacks of each…
