I recently got asked a question about how to managed orphaned objects in vSAN, previously with VMFS this was being managed with a PowerShell script, but the customer couldn’t get it to work with vSAN. Which is expected behaviour as managing these vSAN namespace associations/objects is not possible via the GUI or script. Instead these […]
Application Ontology I’ve been thinking about the different services, policies and functions that support the delivery of applications to individual lines of business. Many of the organisations seem to struggle with this more than anything else in moving toward cloud adoption. As I’m often found saying “the technology can pretty much be made to do […]
Following on from the VMware licence change announcements, detailed here. I thought I’d take a quick look at the accompanying PowerShell module to see what the output looks like and what we can do with data that it gathers. The VMware KB for the PowerShell module includes details on how to import and usage. You […]
Simple Network Mapping In an earlier post I demonstrated how you could use a very simple toolset such as VMware tools and Netstat to create visualisations for what devices are talking to each other on a network. I had a few thoughts of my own on some additional simple steps that could be taken to […]
Network Mapping I had fun working out a simple way to extend application discovery using VMware tools, following a retweet or two (or 17) it seems like a lot of folks enjoyed reading about it too. So fresh from putting together a simple method to interrogate application data, helped by some very clever engineering from […]
Application Discovery I read with great interest the recent article from William Lam regarding application discovery being included in VMware Tools version 11. I’ve worked for many organisations in the past where having access to this information has been crucial for both strategic planning and operational activities. Previously to get that information to support those […]
The impact of gravity on the cloud, what am I talking about now… Gravity is defined as “the force that attracts a body towards the centre of the earth”, that can be extrapolated onwards to state “or towards any other physical body having mass”. It’s a force that has shape everything in our universe. Which […]
One of the highlights of last year was the VMUG National user conference held at the space centre in Leicester. A fantastic venue for not only the conference event but for the pre event vCurry and quiz, so it’s no surprise that it’s being held there again this year. The vCurry on the 26th and […]
When there is an outage, it is natural to panic a little and maybe try a rush troubleshooting steps. In my experience this is oftentimes counterproductive. Symptoms can often be missed as the root cause, which has the net effect of extending the time to resolution. So where would I suggest is the best place to start, well that in part depends on the symptoms. However, the log files will tell you everything that you need to know.
Working with a customer last week I came across an interesting gotcha when connecting the Skyline Collector to vCenter. I picked up the case as the customer was having difficulty gathering logs for a case raised with VMware GSS, they couldn’t log into the console of the collector as root and were not clear how […]
