Virtualisation Podcasts – Keeping your finger on the Pulse

For many years I’ve found listening to Podcasts a great way to keep up-to-date with Virtualisation and Technology.

It all started with the VMware Communities Roundtable podcast, where I quickly realised the commute to work didn’t have to be “dead time”.

Here’s my current list of Virtualisation and Tech podcasts:

  1. Packet Pushers Datanauts
  2. Speaking in Tech
  3. In Tech We Trust Podcast
  4. The Cloudcast (.net) – Weekly Cloud Computing Podcast
  5. The Full Stack Journey
  6. Virtually Speaking Podcast
  7. The Geek Whisperers
  8. VMware Communities Roundtable
  9. Cloud Insiders
  10. vChat (MP3 VERSION) – The Latest in Virtualization and Cloud Computing
  11. The Data Center Insiders Podcast: Virtualization | Cloud Computing | Enterprise IT | VMware | EMC

The best Podcast app I’ve found to date is Overcast, as it has very useful features including Voice Boost and Smart Speed, Playlists, and a great UI.
Oh yeah, and it’s free!

I’ve you want to quickly import the above podcasts, download and import my OPML file here: overcast-adam-rush

Find Upgradeable vShield Edges

I was recently asked if there was a quick way to find out how many vShield Edges were out-of-date and could be upgraded in a vCloud Director environment. I didn’t know of any, so I turned to my good friend PowerCLI and came up with this:

This script does assume that at least one of the vShield Edges in your environment is up-to-date, as it looks for the highest available version deployed and not the known latest version.

VMware Training Resources

I regularly get asked where good VMware training resources are found for various VMware products, so I thought I’d better create a page I can add links to as find them.

vCloud Director

Since I’ve had a focus on vCloud Director for the past few years, these links are fresh in my mind:

  1. VMware has recently updated their Fundamentals course, so this is probably the best place to start: VMware vCloud Director Fundamentals 2016

vCloud Networking

  1. Networking is often a tricky area for new users of vCloud Director, so here is a the best presentation I’ve found so far that explains how the different networking components fit together: https://youtu.be/EZw1UemLBoE
  2. http://www.yellow-bricks.com/2010/09/07/vcd-networking-part-1-intro/
  3. http://www.yellow-bricks.com/2010/09/09/vcd-networking-part-2-network-pools/
  4. http://www.yellow-bricks.com/2010/09/15/vcd-networking-part-3-use-case/

vCloud Design

  1. vCloud Director Design and Scale: https://youtu.be/dzX6DgUL2hQ

I’ve just found this page which includes most of the above links and more: http://blogs.vmware.com/vcloud/2010/09/top-resources-to-learn-about-vcloud-director.html

I’m a big fan of Pluralsight and can highly recommend these courses:

Create a Custom View in Event Viewer to show Reboot Events

Scenario

A server reboot can explain related events and alarms triggered by monitoring systems, so it’s always handy to check for reboots first when troubleshooting.

With this in mind, you want a quick and easy way of finding out when the server last rebooted.

Solution

You need to create a Custom View in Event Viewer, that will only show shutdown and startup events, including reasons why the server rebooted.

Here’s the steps to create the Custom View:
