How It works

 Nutanix Pulse HD provides diagnostic system data to Nutanix support teams to deliver pro-active, context-aware support for Nutanix solutions. The Nutanix cluster automatically and unobtrusively collects this information with no effect on system performance. Pulse HD shares only basic system-level information necessary for monitoring the health and status of a Nutanix cluster.   OK, this is all great but let’s get to real benefits, shall we? Q 1. Why would you enable it? A. Well, for several reasons: So that if you have an issue that you raise with Nutanix support we would be able to start looking at the data about your cluster immediately without making you answer many questions that are often crucially important for a prompt issue resolution. In essence, to reduce the amount of time it takes to fix the problem. So that when Nutanix engineer requires logs they would be able to co

Please Help: As per this video, when the new data is written to the cloned/snapshotted vDisk, what happens when we delete a snapshot? Say we created three snapshots and deleted a second snapshot which have new data written while the base vDisk was read only, what happens to the newly written data? Will it be committed to the base vDisk or the current state snapshot will be alive and other will be deleted? https://www.youtube.com/watch?v=uK5wWR44UYE

Hi, I'm already consuming API V3.0 to retrieve data from Nutanix Element. But i',m not figure how can i get usage stats info (CPU, RAM, DISK) from hosts or VMs. There's a way to do that on V3 or i need to call v2 or v1?

Hello All, The infrastructure team within my organization has recently rolled out several Nutanix environments. Unfortunately we are only able to discover the individual VM's and not the actual appliances. When we tried to address this with the Infrastructure team it was stated that no SSH credentials can be provided as the only credential come from the vendor. Our Discovery tool only supports Nutanix discovery via SSH. Which leads me to my Question? Is anybody performing Discovery on Nutanix appliance and VM's using Discovery tools in there environment and if so how are you achieving this?

I just had a security scan done against my cluster running AOS 5.5.6 and the only 'high' risk that came back was with cve-id CVE-1999-0548 (NFS Server Without Shares Detected): Description; A superfluous NFS server that is not sharing any file systems has been detected. How to Fix; Disable the NFS server. Obliviously, I don't think I want to disable the NFS server service on all of my cvm's - is there any official documentation that I can share with my peers to support this so that I can get an exemption from this risk on these systems?

I'm adding workloads a new Scenario with Sizer Nutanix and I have a doubt about the sizing design because when I add a MV with 384 GB RAM the recomendation of Nodes are only 256 GB or 192 GB of RAM Memory. Could we explain why this. Regards

Hi Team, Please let us know how to get below values using v2 apiversion. Previously we are using apiversion v1 and getting metrics using /vms https://hostname4:9440/PrismGateway/services/rest/v1/vms/ Now with api version v2 we are not able to get below mentioned metrics hypervisor_cpu_usage_ppm not able to find this with both urls(vms,virtual disks) hypervisor_memory_usage_ppm not found memoryCapacityInBytes not found ipaddresses not found but found requested_ip_address are both same?? controllerVm not found Able to get few metrics using virtual_disks and above mentioned metrics we are not able to get, Are these not available in v2 or modified to anyother url.

Hello, I need to understand how nutanix snapshot he lives together with vmware snapshot. It's possible to protect VM with Nutanix snapshot although maybe some users make snapshots from vmware side ? Do they work together ? are there any contraindications or special attentions ? Do they not interfere with each other? I think only be careful not to interfere any restore snapshot from nutanix side with any backup/snapshot made vmware side (aka veeam) ? Thanks Manuel

According to the Prism Web console guide, there is no mention about how to create a two-node cluster. https://portal.nutanix.com/#/page/docs/details?targetId=Web-Console-Guide-Prism-v510:wc-cluster-single-node-c.html#nconcept_fxk_fxl_pbb It might be this ? " cvm$ cluster create -s --redundancy_factor=2" Thanks, Kazu

I'm new to Nutanix and learning as I go. I'm looking at monitoring and alerting and noticed an alert that has not auto resolved. The specific alert is: Node Marked To Be Detached From Metadata Ring I've run ALL NCC Health Checks on the node and it comes back healthy. This alert is set to auto resolve but for some reason will not resolve. I check policy and the auto-resolve checkbox is checked. I did some digging and found a KB article (#000004269) for alert_auto_resolve_helper. I read about this NCC check and I don't see this as an available check in my environment. Any thoughts and tips are appreciated. Thanks!

Hi, My customer is considering leveraging NearSyncDR for their production clusters. Looks like I have to explain to them how NearSync should be configured and how it works to match their needs for future plan. As it matters, I have dived around Nutanix portal for some documents related to this technology but nothing explains clearly why it should run by its behavior in the example below: In the case I configured a schedule that repeats 1 min and retention policy of local cluster for 5 days, NearSync will work as that it will: Create a snapshot per minute and retain it for 15 minutes. Create hourly snapshots and retain for 6 hours. Create daily snapshots and retain for 5 days. So the question is if a snapshot A was created and deleted in 15 mins later, in the case user wanted to use this snapshot A to recover his file, how did he do? Is snapshot retaining time able to be changed by any command?

Hi Friends, It's nice joining you in this wonderful community. I'm Ridwan Oladipupo from Algorism Limited, Nigeria. I'm representing my company as a System Engineer saddled with the responsibility of handling the technicalities of Nutanix during POC. Please I'm absolutely new to the system, I've started with nutanix school, but I felt that is not sufficient enough to get the Job done. I need to get with the guys doing the job. I would be glad if anyone can volunteer to mentor me on this solution. Thanks in anticipation.

Hey guys,I don't have Nutanix and I want to practice on Nutanix - is there virtual image I can use for practice?

Hi, I can see both the NGT and vmware tools in a VM deployed in Nutanix Esxi cluster,when access it via prism? Which one I can able to install?Is there any difference between NGT and Vmware tools?or shall I install NGT in a VM deployed in Nutanix ESxi cluster?Please clarify Regards Jai

There appears to be an issue with the latest Powershell Cmdlets for Version 5.11 that reports itself as Version 5.1.1 (not 5.11) so there is a mismatch. This will bring up a Warning dialogue box asking you if you want to continue with this mismatch (Cluster Version 5.11 and CmdLets Version 5.1.1). This can affect any Powershell Automation Scripts you have running that will be waiting for user intervention! You can change the Nutanix Connection method to Force the Connection using the following syntax: Connect-NTNXCluster -Server "Your server here" -UserName "Your user" -Password "Your password" -AcceptInvalidSSLCerts -ForcedConnection Note: It is the ForcedConnection that enables the bypass of the mismatch for your scripts. Hopefully they will update the Version with the next iteration of the Cmdlets without the apparent typo of 5.1.1 instead of 5.11. Please feel free to "Like" to mark as "Best Answer"

Nutanix REST API gives flexibility to a developer or an administrator to create scripts which can execute administrative jobs on a Nutanix cluster. Using the API, you can request information about different entities in the cluster or even change some configuration. Everyone at the end of the day wants to make sure that their infrastructure is fully secure.  So what about Authentication? What kind of authentication does REST API require?   Nutanix support multiple authentication options. Want to know about them and how to configure and use them in your scripts?

Hello, I will need to power off a "Metro Standby Site", which has VMs running on it. I would like to manually migrate those VMs to the primary (active) site and Shut down / Power Off the nodes in the Standby site approx. 24-36 hours. All VMs need to be running on the active side and no VMs are to be restarted (RTO + RPO =0). The steps I propose to take to achieve the goal are as follows: I have included as much environment info as possible. Any insight or corrections to this process are welcome. Thanks in Advance Phase I (Configure Standby Site) Disable/suspend the (x1) asynch PD (from Primary) Update VMware DRS Rules (Manual) (from Primary) Disable HA Manually perform vMotion of all VMs to active site. Configured VM affinities to the hosts of the primary site and set the DRS rules to Fully Automated. Create new VMGroup and Host Group if n

Can you use a FC card in one node of a Nutanix cluster to do a storage Vmotion / migration to the New esxi Hosts in the cluster ? FC card will present the current VMFS partition to the new esxi host running in the cluster .Then storage vmotion the vm's across to the new storage( NFS partition in the nutanix cluster ) Is this possible ? Prefered option as NFS would only be on a 1 gig network and we need to do this quickly Any input will be appreciated ?

Maintaining a big infrastructure requires planning and knowing your architecture inside and out.Let's say, sometimes you need to check the upgrade history of different components in your cluster.Sometimes you want to know when you last upgraded AOS or Nutanix Files.The timestamp of the upgrade.Let's say you want to plan a future upgrade and creating a time-line and want to know when you upgraded the software last and at which version.We all need this information, either to maintain a proper record of our cluster infrastructure or to plan the future upgrade.So how can we achieve this?Give the following Knowledge base article a read to find out the upgrade history of different components in your cluster and plan your future upgrades accordingly.KB-1151 Want to know how upgrades work in Nuta

Could we get some more documentation on this command?Clone-NTNXVirtualMachineOne of the required parameters is -SpecListI would like some clarification on this parameter and how to use it. Is this an array of values? Am I linking to a csv or json file?An example would be nice.Using the UI, I currently clone a reference image to create vm’s and I would love to get a PS script to work to do the same. I can get it to work with the ACLI commands but PS is a bit more versatile and I believe I could get it to do more if I understood this command and specifically this parameter better.

Nutanix offers a distributed data and control plane, so it’s fairly easy to start, stop and graceful shutdown a cluster. Even, in abnormal / dirty shutdowns, Nutanix cluster has powerful self-healing capabilities - as all data & meta-data is distributed across the cluster which significantly reduces the chances for data corruption or data-loss. However, as a Nutanix Cluster hosts business critical data and applications, it is important to ensure all services stop in a graceful manner and all data + meta-data is consistent. This allows the cluster to be restarted in a healthy - usable state later.There can be several reasons to gracefully shutdown a running Nutanix AHV & AOS Cluster. When shutting down a Nutanix Cluster, following order needs to be followed:User VMs Shutdown AOS Shutdown - Data services / Cluster com
