Monitoring temperature and humidity with a Raspberry Pi 3, DHT22 sensor, InfluxDB and Grafana
24/07/2018 | Sam

I recently started looking into ways of monitoring the temperature and humidity in my garage – for two reasons. Firstly, I have my lab workload cluster out there in the form of a Dell C6100, and I’ve noticed with the recent weather that the temperature in there gets…a bit warm. Secondly, I like to brew […]

Upgrading PKS with NSX-T from 1.0.x to 1.1
29/06/2018 | Sam

Yesterday, Pivotal Container Service 1.1 dropped and, as it’s something I’ve been actively learning in my lab, I wanted to jump on the upgrade straight away. PKS with NSX-T is a really hot topic right now and I think it’s going to be a big part of the future CNA landscape. My Lab PKS 1.0.4 […]

VMware Clarity based WordPress Theme – v0.1
20/06/2018 | Sam

A couple of days ago I saw a tweet from Cody De Arkland showing his new tweaked VMware Clarity based theme on his website. Staying up until 3am to get the brisket on, so what do I do? Work on tuning up https://t.co/YDiFkGIKLY with some better @VMwareClarity styling! Check out the differences below! Subtle changes but […]

GDPR, blogging and DefinIT
22/05/2018 | Sam

So…this is a frustrated sort of post. As you are most likely to already know, the new data protection laws (GDPR) are coming into effect on the 25th May 2018. I must emphasise that I am not an expert on GDPR, this post is my layman’s conclusion for my specific circumstances. I run this blog as […]

vRealize Lifecycle Manager 1.2 VC data collection fails when NSX-T hostswitches are in use
18/04/2018 | Sam

When vRealize Lifecycle Manager 1.2 was released recently, I was keen to get it installed in my lab, since I maintain several vRealize Automation deployments for development and testing, as well as performing upgrades. With vRLCM I can reduce the administrative overhead of managing the environments, as well as easily migrate content between environments (I’ll […]

Three Tier App for vRealize Automation
26/03/2018 | Sam

One question I’m asked quite a lot is what I use for a 3-tier application when I’m testing things like NSX micro-segmentation with vRealize Automation. The simple answer is that I used to make something up as I went along, deploying components by hand and generally repeating myself a lot. I had some cut/paste commands […]

Retrieve Blueprint or Virtual Machine Custom Properties using the vRealize Automation API
02/02/2018 | Sam

Just a quick post today, as I was working with a customer recently and we were trying to retrieve the Custom Properties assigned to a vRealize Automation 7.3 deployed Virtual Machine, similar to the one in the image below. It’s not as intuitive as you’d like it to be because of the split between IaaS […]

NSX 6.x Network Communications Diagram
26/01/2018 | Sam

There are a few NSX Communications network diagrams floating around, but none have really displayed the info in a way I found to be clear or complete enough. To that end, I have been working on a diagram that covers as much of the communications between NSX Components as I can. I’ve currently only covered […]

vRealize Automation 7.3 and NSX – Micro-segmentation strategies
19/01/2018 | Sam
Day 2 Actions Micro-segmentation Strategy

vRealize Automation and NSX integration has introduced the ability to deploy multi-tiered applications with network services included. The current integration also enables a method to deploy micro-segmentation out of the box, based on dynamic Security Group membership and the Service Composer. This method does have some limitations, and can be inflexible for the on-going management […]
