Interrogating data using modern applications

  • simon 

Interrogating data using modern applications I love working with data and with visualisations. I am often at my happiest when working with a large data set trying to find the answer to questions or trying to present data in a way that make it more accessible without losing its meaning.  In the UK, government departments are duty bound to publish figures about all manner of things from health and education to the economy and crime. … Read More »Interrogating data using modern applications

PowerShell: Searching guestinfo.appinfo for an Application or Service

  • simon 

PowerShell: Searching guestinfo.appinfo for an Application or Service VMware Tools 11 can be configured to collect information of running services inside a virtual machine.  When the information is captured it is stored in the advanced setting guestinfo.appinfo.  I’ve written about this before and how that information can be exported to a CSV and transformed with PowerBI to visualise application data in the data centre. This data often provides a significant challenge to get at using… Read More »PowerShell: Searching guestinfo.appinfo for an Application or Service

Exporting vROPs Alert and Symptom Definitions as CSV

Exporting vROPs Alert and Symptom Definitions as CSV I saw a question over on VMTN asking how to export Alert and Symptom definitions from vROPs from the GUI.  It is perfectly possible to do that with vROPs 8.1, but you are going to need to go through page after page of definitions and export them one page at a time.  The exported format is also XML. This is much much easier with access to the… Read More »Exporting vROPs Alert and Symptom Definitions as CSV

Tanzu Mission Control – Adding a vSphere 7 Tanzu Kubernetes Cluster

  • simon 

Tanzu Mission Control – Adding a vSphere 7 Tanzu Kubernetes Cluster One of the great parts of my job is that I get to collaborate and learn from some seriously clever folk in my team and across the company.  Over the past few weeks I’ve been working in the same lab as Dean Lewis.  We’ve been exploring Cloud Foundation 4, Tanzu, Bitnami, Openshift and how those components integrate with the existing VMware SDDC portfolio. Tanzu… Read More »Tanzu Mission Control – Adding a vSphere 7 Tanzu Kubernetes Cluster

vRealise Orchestrator 8.0.1 installation errors

vRealise Orchestrator 8.0.1 installation errors As part of something else that I’ve been working on I needed to install vRealize Orchestrator (vRO) into the lab.  I’d not installed the latest versions of vRO but I was aware that the architecture had changed from earlier versions, and was now built upon kubernetes. vRO Deployment vRO is deployed from an OVA downloaded from the MyVMware portal, the file for vRO 8.0.1 has the catch name of “O11N_VA-8.0.1.7355-15296158_OVF10.ova”. … Read More »vRealise Orchestrator 8.0.1 installation errors

Windows 10 Packet Loss – vSphere 7 and NSX-T 3

  • simon 

Windows 10 Packet Loss – vSphere 7 and NSX-T 3 I was recently working with a customer that was experiencing some interesting network packet loss in their environment – insofar as any packet loss can be interesting. The reported issue was that any Windows 10 virtual machine was impacted with up to 60% packet loss when testing with ICMP packets.  This impact was not observed with any other operating system. Having torn apart the NSX-T… Read More »Windows 10 Packet Loss – vSphere 7 and NSX-T 3

  • simon 

vROPs Dashboards – Kubernetes Namespaces ***Dashboard now available on VMware Code and GitHub*** A few weeks ago I installed the vROPs management pack for container monitoring, which provides a great overview of the kubernetes cluster, nodes and pods in the environment. This dashboard is built from the context of the containers world adaptor and is pulling information from the kubernetes estate using cAdvisor.  As mentioned above the default dashboard views are built around the cluster,… Read More »vROPs Dashboards – Kubernetes Namespaces

VMware PowerShell – VM Advanced Settings – ‘guestinfo.ignition.config.data’ Working this evening with my colleague Dean this evening he asked me to create a quick PowerShell script to help him with an OpenShift 4 installation.  What he needed to do was to edit the advanced setting ‘guest.ignition.config.data’ with a base64 encoding value. The quick and dirty version of the script is below; #Edit ‘Base64_64’ values to the bootstrap, master and worker variables below $bootstrap = ‘Base64_Value’… Read More »VMware PowerShell – VM Advanced Settings – ‘guestinfo.ignition.config.data’

VMware PowerShell – Useful HealthCheck Remediation Scripts

  • simon 

VMware PowerShell – Useful HealthCheck Remediation Scripts I get to conduct and review the recommendations and findings from a VMware HealthCheck and Best Practice Reviews.  Recently I conducted one and to help with remediation I pulled together some simple PowerShell Scripts to remove the manual effort. Disconnect all Connected CDs from VMs A very common finding is connected CDs preventing DRS and VMotion operations from occurring.  This script solves that by disconnecting them all; #add… Read More »VMware PowerShell – Useful HealthCheck Remediation Scripts
