Have you ever wondered how to quantify the benefits of virtualization to your management? If so, please consider using vBenchmark. vBenchmark measures the performance of a VMware virtualized infrastructure across three categories:

  • Efficiency: for example, how much physical RAM are you saving by using virtualization?
  • Operational Agility: for example, how much time do you take on average to provision a VM?
  • Quality of Service: for example, how much downtime do you avoid by using availability features?

vBenchmark provides a succinct set of metrics in these categories for your VMware virtualized private cloud. Additionally, if you choose to contribute your metrics to the community repository, vBenchmark also allows you to compare your metrics against those of comparable companies in your peer group. The data you submit is anonymized and encrypted for secure transmission.

Key Features:

  • Retrieves metrics across one or multiple vCenter servers
  • Allows inclusion or exclusion of hosts at the cluster level
  • Allows you to save queries and compare over time to measure changes as your environment evolves
  • Allows you to define your peer group by geographic region, industry and company size, to see how you stack up

What’s new in version 1.0.2

  • Fixed bugs that prevented some customers from deploying vBenchmark appliance with vCloud Director and vCenter Server 4.0
  • Fixed a bug that caused network settings not to persist after the reboot
  • You can change the network configuration of the VM via the web interface, please point your browser to https://ip.address:5480
  • Updated VMware Tools

What’s new in version 1.0.1

  • Added a checkbox to include or exclude vCenter license keys when submitting the data to the community repository
  • The application now listens on port 443 (https), requests to port 80 will be automatically redirected to 443
  • The appliance will now prompt you to change the root password at first logon
  • Fixed bugs that prevented some customers from proceeding to the dashboard when they have ESX 3.x hosts in their cluster or are using vCenter credentials that did not have access to the full inventory
  • vBenchmark application log is now written to the VM serial port. If you are using the VMX package, the serial port output will be redirected to a file named vBenchmark.log in the virtual machine folder. If you are importing an OVA or OVF, you need to manually add a serial port device and specify a filename.

Fling Labs! Latency Sensitivity Troubleshooting Tool

Source: Fling Labs


The Latency Sensitivity Troubleshooting Tool provides scripts and examples to troubleshoot configuration and performance problems with the Latency Sensitivity feature in VMware vSphere 5.5.


  • Python script that runs on ESXi to check virtual machine and physical NIC (PNIC) configuration to monitor host, virtual machine, and PNIC performance.
  • Python program to process traces from pktcap-uw for a ping workload and print time spent in ESXi on the receive path, time spent in the virtual machine, and time spent in ESXi on the transmit path.
  • A simple C program demonstrating the trace format generated by pktcap-uw. The C program was tested on an x86_64 Linux virtual machine.
  • Example SystemTap scripts to break down ping and netperf TCP_RR latencies inside a Red Hat Linux guest. These scripts were tested on a Red Hat Enterprise Linux 6.2 virtual machine.


Tech Preview: I/O Analyzer VMware Fling Labs


VMware I/O Analyzer is an integrated framework designed to measure storage performance in a virtual environment and to help diagnose storage performance concerns. I/O Analyzer, supplied as an easy-to-deploy virtual appliance, automates storage performance analysis through a unified interface that can be used to configure and deploy storage tests and view graphical results for those tests.

I/O Analyzer can use Iometer to generate synthetic I/O loads or a trace replay tool to deploy real application workloads. It uses the VMware VI SDK to remotely collect storage performance statistics from VMware ESX/ESXi hosts. Standardizing load generation and statistics collection allows users and VMware engineers to have a high level of confidence in the data collected.

Please post comments and questions regarding this fling to the I/O Analyzer Community.


  • Integrated framework for storage performance testing
  • Readily deployable virtual appliance
  • Easy configuration and launch of storage I/O tests on one or more hosts
  • Integrated performance results at both guest and host levels

Fling Labs: IOBlazer – IOPS and bytes/s and IO latency and playback VSCSI traces captured on VMware ESX through the vscsiStats utility

Source: Fling Labs


IOBlazer is a multi-platform storage stack micro-benchmark. IOBlazer runs on Linux, Windows and OSX and it is capable of generating a highly customizable workload. Parameters like IO size and pattern, burstiness (number of outstanding IOs), burst interarrival time, read vs. write mix, buffered vs. direct IO, etc., can be configured independently. IOBlazer is also capable of playing back VSCSI traces captured using vscsiStats. The performance metrics reported are throughput (in terms of both IOPS and bytes/s) and IO latency.

IOBlazer evolved from a minimalist MS SQL Server emulator which focused solely on the IO component of said workload. The original tool had limited capabilities as it was able to generate a very specific workload based on the MS SQL Server IO model (Asynchronous, Un-buffered, Gather/Scatter). IOBlazer has now a far more generic IO model, but two limitations still remain:

  1. The alignment of memory accesses on 4 KB boundaries (i.e., a memory page)
  2. The alignment of disk accesses on 512 B boundaries (i.e., a disk sector).

Both limitations are required by the gather/scatter and un-buffered IO models.

A very useful new feature is the capability to playback VSCSI traces captured on VMware ESX through the vscsiStats utility. This allows IOBlazer to generate a synthetic workload absolutely identical to the disk activity of a Virtual Machine, ensuring 100% experiment repeatability.

Fling labs: PowerActions for vSphere Web Client

Source: Fling Labs


PowerActions integrates the vSphere Web Client and PowerCLI to provide complex automation solutions from within the standard vSphere management client.

PowerActions is deployed as a plugin for the vSphere Web Client and will allow you to execute PowerCLI commands and scripts in a vSphere Web Client integrated Powershell console.

Furthermore, administrators will be able to enhance the native WebClient capabilities with actions and reports backed by PowerCLI scripts persisted on the vSphere Web Client. Have you ever wanted to “Right Click” an object in the web client and run a PowerCLI script? Now you can!

For example I as an Administrator will be able to define a new action for the VM objects presented in the Web client, describe/back this action with a PowerCLI script, save it in a script repository within the Web client and later re-use the newly defined action straight from the VM object context (right click) menu.

Or, I as an Administrator can create a PowerCLI script that reports all VMs within a Data Center that have snapshots over 30 days old, save it in a script repository within the Web client and later execute this report straight from the Datacenter object context menu.

Or better yet, why not share your pre-written scripts with the rest of the vSphere admins in your environment by simply adjusting them to the correct format and adding them to the shared script folder.

Ultimate Deployment Appliance: Deployment Appliance for VMware ESXi/Windows/Linux: PXE boot installation

Source: Ultimate Deployment Appliance Home page

The following is from the web site.  “When you go to your friends house to fix his/her computer you want to be prepared. ”

Cool.  Sounds like a simple SCCM.
What is the Ultimate Deployment Appliance?

  • Unattended OS installations (Windows, Linux, ESX, Solaris) over the network set-up in minutes!
  • Publish your favorite recovery/system maintenance tools over the network!
  • PXE Booting, Remote Installation Services, Kickstart, Jumpstart, Autoyast in a box!

When would you use this?

  • When you are trying to install a system that doesn’t have a CDROM drive, but does have a network card (these days ultra-thin laptops and such don’t have an optical drive)
  • When you have to install an operating system on different pieces of hardware.
  • When you have to install systems and want things to go automated and reproducible.
  • When you go to your friends house to fix his/her computer you want to be prepared. Instead of removing all that unwanted stuff you might as well start fresh. Bring your own system (laptop?), hook it up to the messed up system with a cross-cable and start re-install the system from scratch fully unattended. Head for the fridge…
  • When you need to do maintenance on your system without the need to carry around a stack of live CD’s.
  • When you want to do this without paying lots of money for commercial products.

How Does it work?

  • Unattended Install The appliance mounts an iso file with a distribution of you favorite operating system and imports the necessary (network) boot-files. It creates a default configuration file for your automated installation and starts hosting the operating system distribution files for network booting.
  • System Tool Publishing Live CD’s and other tools are imported entirely to the Ultimate Deployment appliance and are published for booting over the network trough PXE.
