efficient-vmware-monitoring-stop-chasing-fires

Spending too much time chasing and stomping fires in your VMware environment, and not enough time cashing checks and playing video ga — um, conducting really important business? As it happens, the bulk of problems with VMware vSphere can be boiled down into one of just a handful of causes. Fortunately, there are VMware monitoring tools available to help you track and correct these issues and get back to that really important business (MARIO KART!).

Are the VM Tools Old or AWOL?

VMware monitoring - old VMware Tools

_A new vSphere always means a new collection of tools. You just have to remember to go get them._The VMware tools are designed to improve the performance of guest operating systems, but the tools are updated each time a new version of vSphere is released. Unfortunately, the tools do not update automatically. Hence, each time you get a new version of VMware, you discover that those tools are outdated or missing. The symptom is usually a message that reads, ‘VMware Tools is out of date on this virtual machine’, or many of the features simply stop working. You can manually update those tools each time you get a new version of VMware vSphere.Are the VM Network Devices Old?If performance is seriously hindered, old VM devices might be the cause. Opvizor recommends a 4-step process for updating the network devices (just to be on the safe site – after the VM has been either backed up or a snapshot has been created):1. Upgrade the virtual machine hardware by:

  • Update the VMware Tools to the latest version and restart the virtual machine
  • Shutting down the virtual machine
  • Right-clicking on the virtual machine
  • Going to ‘All vCenter Actions’, to ‘Compatibility’, and then clicking on ‘Upgrade VM Compatibility’
  • Select the new VM compatibility mode to the latest compatibility mode which, as of today, is ESXi 5.5 and later, then click OK

2. Add a new virtual network adapter by:

  • Clicking ‘edit settings’ for the virtual machine
  • Clicking on ‘Select’ next to New Device
  • Clicking on ‘Network’
  • Clicking ‘Add’ then setting the new virtual network device’s network to match the current network of the out of date virtual network adapter
  • Expanding the virtual network device
  • Setting the adapter type to the latest version (which at this time is VMXNET 3)

3. Remove the old virtual network adapter (which is still in settings) by clicking on the X next to the old adapter, then clicking OK

4. Power On the virtual machine and, once booted, reconfigure the new virtual network adapter with the IP configuration of the old virtual network adapter.

Other Frequently Seen Problems

vSphere monitoring - old network device

VMware does not come with antivirus or antimalware software. You have to acquire and install that separately, but it is essential for maintaining safe, well-functioning systems. You should definitely look into VMware vSphere API based Antivirus solutions.

There are some other common issues that lead to problems with your VMware environment, as well, such as:

• Inadequate 

memory limits

• Issues with 

VM Snapshots

• Problems with 

VM logging

• A 

virus on the Host or a Guest

Fortunately, a good VMware monitoring tool can help you stay on top of these issues. Visit Opvizor to 

get a better grasp on your VMware environment

 today, and get back to doing what you enjoy doing most — not micromanaging your VMware.

Use Case - Tamper-resistant Clinical Trials

Goal:

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.).

Implementation:

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

Goal:

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.

Implementation:

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

Goal:

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, …)


Implementation:

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

Goal:

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.

Implementation:

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

Goal:

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.

Implementation:

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.
