Capture Code – vSphere Web Client

One of the conveniences of administering VMware solutions is being able to use code to create scripts to perform repetitive tasks or automate processes

One of the vSphere Web Client features that can help those new to the PowerCli is the Capture Code, it basically allows you to list and save the Powercli commands of the actions you are doing with the vSphere Web Client.

To activate it just access the vSphere Web Client, from the Menu select Developer Center

Select Code Capture and enable it by placing the “Enable Code Capture” flag on the right (which turns green)

At this point, a space will appear in our frame where the commands will be listed with some operations, such as Clear and start another, Copy and Download

Where the Download option generates you the ps1 file with the Powercli commands of the recorded operations

To start and stop a recording session you can use the buttons:

Or the red button that appears at the top of the WebClient once “Enable Code Capture” is enabled

VMware Skyline Health Diagnostics

August 25, 2021August 25, 2021 fabio1975Diagnostic, Diskgroup, log, Skyline, vSAN, vSphereLeave a comment

Last Year VMware release a Diagnostic Tool for Analyze vCenter, vSAN and ESXi infrastructure.

VMware Skyline Health Diagnostic is a Virtual Appliance (based on Photon OS) for analyzing our vSphere infrastructure.

In this link major info for install:

Introducing VMware Skyline Health Diagnostic Tool

but what can it be useful for?

Imagine you have a vSAN infrastructure and at some point, a diskgroup fails but errors are reported on the disks. With this tool, we can analyze the logs exported from the ESXi host on which the diskgroup resides and identify on which physical disks I / O errors have been highlighted

vSphere and Certificates

June 29, 2021 fabio1975Certificates, ESXi, PKI, VMCA, vSphereLeave a comment

vSphere use TLS Certificates for protect and security communication from vCenter to ESXi host and when the user access to vCenter WEB GUI.

There are many possible configurations:

Full Managed Mode -> All certificates are managed from VMCA
Hybrid Mode -> The communication certificates for traffic from vCenter to ESXi are managed from VMCA. The Admin user import from Private PKI only the SSL certificate for Access to WEB GUI
Subordinate CA Mode -> Configure the VMCA as a Subordinate CA of Private PKI
Full Custom Mode –> All Certificates are generated and managed from the local Private PKI

The best solution is Hybrid Mode for correct balance of Security and effort for implementation.

Attualmente è disponibile la possibilità di utilizzare una trial della soluziona Horizon Cloud di VMware su cloud AZURE.

La trial è disponibile per 90 giorni (prima del covid-19 erano meno estesa).

Per procedere nell’utilizzo della trial è necessario eseguire una serie di semplici step:

Acquire Horizon Cloud Service on Microsoft Azure
Prepare Microsoft Networking and AD
Azure Deploy Horizon Cloud Service On Microsoft Azure
Deploy Microsoft Azure-Based RDS Host and VDI Desktop
Install Applications and Assign Users

Procediamo con ordine e partiamo da Acquire Horizon Cloud Service on Microsft Azure dove:

– Attiviamo le licenze Trial e gli step che consiglio sono:

Crearsi un account GMAIL
Registrarsi al sito MyVMware con il nuovo account GMAIL
Compilare l’apposito FORM (Request Form-Horizon Universal License Free Trial*)

Le credenziali create per accedere MyVMware saranno anche quelle che ci permetteranno l’accesso al portale https://cloud.horizon.vmware.com

Nell’apposito FORM verrà richiesto:

– Tipologia di trial (Azure, On-Premises, AWS, Azure VMware Solutions, Google Cloud VMware Engine)

– Numero e tipologia (Concurrent o user) delle licenze Horizon Universal

– Location della VMware Horizon Panel (America, Europa ecc..)

– Azure Region del deploy dell’ambiente

– Utilizziamo una Microsoft Azure Subscription

Dal portale azure attiviamo la nostra Subscription dove andremo a crare i servizi necessarei per il deploy dei componenti (Horizon, VM ecc)

*Horizon Universal License sono le nuove licenze Horizon che posso essere utilizzate sia per ambienti on-premises o su cloud

vSphere Skyline Health

May 17, 2020February 27, 2021 fabiovmware, vSAN, vSphereLeave a comment

Uno degli aspetti che mi spingono a proporre di aggiornare le infrastrutture VMware vSphere alle versione 6.7u3 è anche la presenza dello skyline health. Strumento indispensabile per monitorare lo stato della infrastruttura

Le informazioni che possiamo velocemente individuare analizzare sono relative a oggetti come i singoli host ESXi, il vCenter e lo stato della vSAN.

Che informazioni possiamo trovarci? Dalle vulnerabilità di sicurezza presenti nella nostra infrastruttura a versioni di firmware da aggiornare. Ovviamente correlate da collegamenti a pagine della KB VMware con informazioni specifiche su come gestirle.

Per poter avere queste informazioni è necessario abilitare il CEIP (Customer Experience Improvement Program).

VMware investe da sempre nella soddisfazione dei clienti e per cui tutto il flusso di gestione e assistenza con l’avvento di skyline ha guadagnato ulteriormente in efficienza.

vCPU:pCPU ratio

October 7, 2019 fabioCORE, CPU, SAN, vmware, vSphereLeave a comment

From official doc VMware:

the following vCPU:pCPU ratios can be considered a good starting point for a design:

o1:1 to 3:1 is not typically an issue

oWith 3:1 to 5:1, you might begin to see performance degradation

o6:1 or greater is often going to cause a significant problem for VM performance

I have found this script in VMware Community Site:

Foreach($esx in Get-VMHost){

$vCPU = Get-VM -Location $esx | Measure-Object -Property NumCpu -Sum | select -ExpandProperty Sum

$esx | Select Name,@{N=‘pCPU’;E={$_.NumCpu}},

@{N=‘vCPU’;E={$vCPU}},

@{N=‘Ratio’;E={[math]::Round($vCPU/$_.NumCpu,1)}}

}

Output is:

Name pCPU vCPU Ratio
