This is a video taken by Rick Sloof at Wednesday, August 23 at the strip in Las Vegas. It was picked up by several big media companies, like the BBC and ABC News. At this day in 2023, the VMware Explore Party took place in the WynnXS Las Vegas.

Dimitri Desmidt over at VMware has created a great presentation about NSX Anti-Malware Detection.

Here's a list with the topics:

What’s new in NSX 4.0.1 NSX Malware Detection and Prevention

• What is it?
• How does NSX Malware Detection and Prevention work?
• Malware Detection and Prevention
• Gateway Malware Detection
• Distributed Malware Detection and Prevention
• NSX Malware Detection and Prevention - Reporting
• NSX Malware Detection and Prevention Requirements / Limitations / Scale

Advanced points:

• NSX Malware Detection and Prevention High-Availability
• Malware File DB Population
• NSX Malware Detection and Prevention Installation
• NSX Malware Detection and Prevention Upgrade
• Supported Windows versions and VMware Tools releases

vSphere Diagnostic Tool is a Python script that runs diagnostic commands on the vCenter Server Photon Appliance to return useful troubleshooting data while running within the confines of the local environment without upstream dependencies.

The motivation behind this tools is to provide multiple Pass/Fail tests to quickly facilitate the rapid isolation of issues encountered in the vSphere environment.

• vCenter Basic Info
• Lookup Service Check
• AD Check
• vCenter Certificate Check
• Core File Check
• Disk Check
• vCenter DNS Check
• vCenter NTP Check
• vCenter Port Check
• Root Account Check
• vCenter Services Check
• VCHA Check

General Improvements:

• VDT now supports 8.0 U1!
• VDT 1.1.5 will no longer support vCenter 6.7, although many checks will still work. 1.1.4 will remain available for anyone still needing it on the 6.x product line.
• Credentials are now validated at the start. The user is notified that checks requiring authentication will not run if password validation fails 3x times.
• The default timeout behavior has changed. It now prompts a user to skip the check or let it run, instead of requiring the --force flag.

VC Database Check:

• The VCDB check now shows statistics levels as well as tasks and event retention policies.
• The VCDB check output is now in line with the results from KB 1028356.

VC VMDIR Check:

• The vmdir check now includes ELM partner information and tests port connectivity over 389, 443, 2012, and 2020 to them. The old port check has been removed in favor of this.
• The vmdir check now looks for stale (native) PSC HA config in the likewise registry

VC Certificate Check

• Certificate expiry time is now displayed with each certificate message.
• he vmdir cert from 6.0 is no longer included in the list of certificate checks

Bug fixes:

• VDT now decodes to utf-8 instead of ascii to avoid parsing errors
• Updated KB references

Maintaining an agile data center infrastructure tends to be a source of headaches for IT leaders and administrators. It doesn't have to be.

Hyper converged infrastructure (HCI) evolves the way that compute, storage, and management are delivered and provisioned to help you cut operational and capital costs, increase information technology (IT) and business agility, and improve application performance.

• Modernize your data center 
• Understand why you need Hyperconverged Infrastructure 
• Deploy a multi cloud platform

Metric is essentially an accounting of systems in operation. To understand the counter properly, hence requires a knowledge of how the system works. Without internalizing the mechanics, you will have to rely on memorizing. In Iwan 'e1' Rahabok's case, memorizing is only good for exams. So grab a cup of your favorite drink, and take some time to truly understand the reasons behind the metrics. You will appreciate the threshold better when you know how it was calculated. 

vSphere ships with many metrics and properties. If we take object by object, and document metrics by metrics, it would be both dry and theoretical. You will be disappointed, as it does not explain how your real world problems are solved.

This book begins with you. It focuses on the problems you are trying to solve when running your operations. It looks at all the use cases and breaks down the metrics from there, which helps you appreciate why the metrics are layered in such a manner.

At 300+ pages, it’s not a light reading. To keep the book size manageable, Iwan has excluded some metrics. To see the full list, see VMware Operations Transformation, 4th Edition. This 900-page book is also open-source and free.
