How It works

As of Nutanix Collector release version 3.0 and later, it is now possible to collect statistics for Hyper-V clusters along with AHV and ESX clusters.From the initial home screen, simply select the “Hyper-V” option from the “Run on” drop-down, then enter the IP address or fully-qualified domain name (FQDN) of a Hyper-V host, followed by the username and password of an Windows administrator from the administrator group. Thereafter, simply select the entities from which you would like to collect statistics and click the “Collect” button.Please note that any Hyper-V hosts being connected to should be running PowerShell version 5 or later. Also, as Collector currently only collects configuration data from Hyper-V clusters, the Collector performance graphs may appear as blank following a su

ESXi 7.0 requires a minimum of 4 GB of physical RAM. Provide at least 8 GB of RAM to run virtual machines in typical production environments.4GB only for the HOSTAnd about AHV?What is the minimum memory for AHV only?, without CVMs and VMs

Hi All, Does anyone know if it’s possible to pass variables into the ‘Custom Script’ / cloud-init section, when creating a VM in AHV via Prism Element?Ideally, I’d like to use the REST API to create (clone) a VM from a template, and pass a ‘Custom Script’ perhaps from an ADSF path, that is able to configure the guest’s Hostname / FQDN based off the VM’s name specified in the REST API call.IPAM and some basic cloud-init config is working, just trying to determine the best way to set the hostname!

Customers can observe cluster issues when they use more than 90 percent of the total available storage on the cluster. This article provides general guidelines on the maximum storage utilization on a cluster. The total available storage capacity on a Nutanix cluster is the sum of all the available storage space across the nodes.Customers should not try to use all the available space in the cluster. Sufficient space should always be available in the cluster in case a failure occurs. For example, when a disk fails in the cluster, the extent groups that were present on that disk have to be copied to other disks to ensure that all the data is at the configured replication factor. If the disk space is unavailable for this activity, then there is a risk of data loss if more failures occur with t

In some scenarios, when you enable the remote support tunnel, it’ll tell you that it has been temporarily enabled but the status will show “disabled”.To troubleshoot, you can start by checking Basic IP connectivity to nsc01.nutanix.net or nsc02.nutanix.net. If that times out, then it is either a DNS resolution problem or a firewall issue.Check the firewall rules of your system to allow outbound connections to nsc.nutanix.com on port 80 or 8443.For more details on troubleshooting, check KB-1044

Hello Team, I’m running a small 3 node cluster, during an AHV upgrade to the latest version one of the servers failed to reboot so AOS started to rebuild trying to restore HA. After several hours rebuilding failed, looking at the logs I saw the message: “not enough space available”. If I’m not mistaken a 3 node cluster can tolerate only one node down, but lets say the two running nodes had enough space, is it possible to restore HA? It basically means that after some time rebuilding, if one of the 2 remaining nodes fails, cluster is still up in a single node mode.Just curious because it looked like AOS tried to rebuild HA despide only 2 nodes were up

Note -  Nutanix highly recommends using Nutanix Move to migrate VMs to AHV. See the Nutanix Move documentation at the Nutanix Support portal. This KB should only be used if Nutanix Move cannot be used or for reference only. For large scale migrations of business critical systems, Nutanix Global Services organization pr

Do you already have many security policies defined within one instance of Flow and, have another instance where you need the same set of policies but do not wish to recreate them? Or, do you wish to simply have a backup of your existing security policies just in case you should ever need to restore them sometime in the future?Flow has the native ability to export (and subsequently import) security policies that have already been defined previously. Policies are exported into a single binary file, which can then be transferred to a different instance of Flow or stored-away for backup purposes.Please also note that, when importing a previously exported binary file, any existing policies which are already defined within a given Flow instance are automatically removed in-favor of the newl

Synopsis: The goal of this workflow is to walk-through troubleshooting VM to VM communication issues in a Nutanix Cluster. Most customers are very vague when they state they have a networking issue. We will go through painting a complete picture of the network topology by asking the right questions and running commands on the Hypervisors.  Initial Triage:Questions to Ask:  What hypervisor is running on the

Hi all.I’ve been trying to figure out how I can execute a PowerShell script inside a guest VM, both Linux and Microsoft, on AHV through the host but can’t find any solid information on the topic.There is a discussion called “Execute Script Inside AHV VM?” but that is only for initial configuration of the VM. I’m looking for a way to execute an arbitrary script on any running VM without having access to the VM through its default network configuration.It’s basically a hosting situation where customer VMs exist within their own isolated environments and I’m responsible for running various scripts for - among other things - joining new servers to AD, installing SQL Server, patching the OS, etc, etc.Looking at this post there seems to be a way to run scripts through NGT but when reading the Nutanix Bible that option seems to be limited to VM creati

If you have a storage container on the cluster and the name starts with a “#”, you may see this error while trying to upload an image:"Could not access the URL nfs://127.0.0.1/%23ISO_Images/.acropolis/image/106ac31b-6236-4534-a2ae-808c08bb912f: Failed to parse the file size" That happens because the URL cannot have the # in the name and it gets automatically replaced with %23. Therefore, this creates the inconsistency between the container name and the URL.To resolve the issue, rename the container and remove the # from the container name and retry the image upload.Take a look at KB-10117 for more information.Check this guide on

To verify if we have replaced DIMM on correct slot and CPU we can use the following method We can look at hardware.history file which records any replacement for example DIMM,SSD,HDD,NIC being made to that node. This file remains local to each CVM After we replace DIMM we will boot the host up Power on CVM and run following command ncc hardware_info update_hardware_info           This will update the hardware.history file present in ~/config directory and it will recognize any new replacement Open hardw

Nutanix Clusters Console receives the results of the status checks performed by AWS to see the status of the instances.Status checks on AWS are performed every minute, returning a pass or a fail status. If all checks pass, the overall status of the instance is OK. If one or more checks fail, the overall status is impaired.    There are two types of status checks, system status checks, and instance status checks. System status checks monitor the AWS systems on which instance runs. Instance status checks monitor the software and network configuration of individual instances.If Nutanix Orchestrator detects that AWS has marked system status or instance status of an instance impaired, following WARNING message will be seen in the Notification Center of the Nutanix Clusters Console: More information on -

Nutanix Move is a very versatile tool which is used to migrate existing VMs, from various storage sources and hypervisors, into a Nutanix infrastructure. Many users have already enjoyed its functionality and ease-of-use.Often, users will migrate multitudes of VMs into their new Nutanix infrastructure using Move, and then either delete or forget about the Move VM itself thereafter. Later, when more VMs are sought to be migrated, users will either reinstall Move again or attempt to leverage the Move VM that remained from the previous migration.For those users leveraging an existing Move VM within their infrastructure and, as it is generally a good idea to use the latest version of Move when possible, it is possible to upgrade the Move VM to the latest available version right from its ow

Hardening is the process of securing a system by reducing its surface of vulnerability, which is larger when a system performs more functions; in principle a single-function system is more secure than a multipurpose one. Reducing available ways of attack typically includes changing default passwords, the removal of unnecessary software, unnecessary usernames or logins, and the disabling or removal of unnecessary services. There are various methods of hardening Unix and Linux systems. This may involve, among other measures, applying a patch to the kernel such as Exec Shield or PaX; closing open network ports; and setting up intrusion-detection systems, firewalls and intrusion-prevention systems. There are also hardening scripts and tools like Lynis, Bastille Linux, JASS for Solaris systems and Apache/PHP Hardener that can, for example, deactivate unneeded features in configuration files or perform various other protective measures. We can implement Securit

Application monitoring provides visibility into integrated applications by collecting application metrics using Nutanix and third-party collectors, providing a single pane of glass for both application and infrastructure data, correlating application instances with virtual infrastructure, and providing deep insights into applications performance metrics. The monitoring integrations dashboard allows you to view information about select applications, such as SQL Server instances, running in the cluster. Before you decide to enable this, there are some pre-requisites that you need to follow.  To learn more about the prerequisites, click here and for more information about Application Monitoring, check the
