Ease of Detecting

Identifying that you have virtual machine with Tools that are out of date or not installed at all is easy to do. The virtual machine Summary tab in vCenter will show the status of the VMware Tools on that specific virtual machine.
To find out of the status of the VMware Tools across the entire vSphere infrastructure, go to the vCenter Inventory level, click on Related Objects, and then go to the Virtual Machine inventory. Here you will likely need to add the “VMware Tools Version Status” column to the report. To do this, right-click on the storage report column headers and click Show/Hide Columns, as shown in Figure 2.
Figure 2: VMware Tools Version
Next, click on the VMware Tools Version Status option to add it to the view, as shown in Figure 2. From there, you can sort and group all the VMware tools versions that are similar by clicking on the column header entitled VMware Tools Version Status, as shown in Figure 3.

Additionally, you can run a PowerCLI script — which you can find at this link — to output the overall VMware Tools status.

Benefits to Solving

The benefits to installing (or at least upgrading) the VMware Tools include:

  • Gaining the ability to shut down or restart the guest OS from the vSphere client

  • Improving guest OS performance
  • Reducing resource utilization and improving VM to host consolidation ratio, which improves the ROI for the virtual infrastructure environment

Ease of Solving

Installing or updating the VMware Tools is quickly accomplished through the vSphere Web Client. This installation or update may not even require a reboot of the virtual machine guest OS. If VMware Tools need to be upgraded, you’ll be prompted on the Summary tab of the virtual machine, as shown in Figure 4.
Figure 4: VMware Tools update
Alternatively, you can right-click on the virtual machine go into All vCenter Actions, Guest OS, and click on Upgrade VMware Tools (shown in Figure 5), then follow the prompts inside the guest OS. If you prefer to use the command line to accomplish your goal, the PowerCLI cmdlet is available via Update-Tools. Figure 5: VMware Tools Update 2

How opvizor Helps

Rather than remembering to periodically search for virtual machines with older versions of VMware Tools, or on virtual machines that don’t have any VMware Tools installed, opvizor continuously scans the environment for virtual machines that need their VMware Tools updated or installed (Figure 6). Not only does this save analysis time, it also ensures that you remain continuously aware of the status of your virtual machines, and that you can ensure that your virtual machines are always performing optimally.

Use Case - Tamper-resistant Clinical Trials


Blockchain PoCs were unsuccessful due to complexity and lack of developers.

Still the goal of data immutability as well as client verification is a crucial. Furthermore, the system needs to be easy to use and operate (allowing backup, maintenance windows aso.).


immudb is running in different datacenters across the globe. All clinical trial information is stored in immudb either as transactions or the pdf documents as a whole.

Having that single source of truth with versioned, timestamped, and cryptographically verifiable records, enables a whole new way of transparency and trust.

Use Case - Finance


Store the source data, the decision and the rule base for financial support from governments timestamped, verifiable.

A very important functionality is the ability to compare the historic decision (based on the past rulebase) with the rulebase at a different date. Fully cryptographic verifiable Time Travel queries are required to be able to achieve that comparison.


While the source data, rulebase and the documented decision are stored in verifiable Blobs in immudb, the transaction is stored using the relational layer of immudb.

That allows the use of immudb’s time travel capabilities to retrieve verified historic data and recalculate with the most recent rulebase.

Use Case - eCommerce and NFT marketplace


No matter if it’s an eCommerce platform or NFT marketplace, the goals are similar:

  • High amount of transactions (potentially millions a second)
  • Ability to read and write multiple records within one transaction
  • prevent overwrite or updates on transactions
  • comply with regulations (PCI, GDPR, …)


immudb is typically scaled out using Hyperscaler (i. e. AWS, Google Cloud, Microsoft Azure) distributed across the Globe. Auditors are also distributed to track the verification proof over time. Additionally, the shop or marketplace applications store immudb cryptographic state information. That high level of integrity and tamper-evidence while maintaining a very high transaction speed is key for companies to chose immudb.

Use Case - IoT Sensor Data


IoT sensor data received by devices collecting environment data needs to be stored locally in a cryptographically verifiable manner until the data is transferred to a central datacenter. The data integrity needs to be verifiable at any given point in time and while in transit.


immudb runs embedded on the IoT device itself and is consistently audited by external probes. The data transfer to audit is minimal and works even with minimum bandwidth and unreliable connections.

Whenever the IoT devices are connected to a high bandwidth, the data transfer happens to a data center (large immudb deployment) and the source and destination date integrity is fully verified.

Use Case - DevOps Evidence


CI/CD and application build logs need to be stored auditable and tamper-evident.
A very high Performance is required as the system should not slow down any build process.
Scalability is key as billions of artifacts are expected within the next years.
Next to a possibility of integrity validation, data needs to be retrievable by pipeline job id or digital asset checksum.


As part of the CI/CD audit functionality, data is stored within immudb using the Key/Value functionality. Key is either the CI/CD job id (i. e. Jenkins or GitLab) or the checksum of the resulting build or container image.
