In Prism Central, the resource usage of VMs in the cluster is displayed, but the disk usage is not. I think is that the disk usage may be display after a few moment of time has passed. Is it normal if the resource utilization of all VMs should be displayed immediately? Or how long does it take to display?For example, is there a document saying "In Prism Central, the CPU and MEM usage of the VM are output immediately, but in the case of disk usage, it takes some time to be output"? In the current Prism Element, the resource usage of VMs is immediately reflected. All resource usage rates such as CUP, MEM, and DISK are output.However, in Prism Central, just disk usage rate cannot be display.  

I have started trying to use powershell 7 to perform queries against Prism Central.I have been able to install powershell 7 as well as install the nutanix.cli moduleI am able to establish a connection to a prism central instance.Server                : server.domain.netVersion               : pc.2020.9.0.1UserName              : account@domainAcceptInvalidSSLCerts : TrueForcedConnection      : False However when I try some basic commands such as get-cluster and get-vm I get the error“Get-Cluster: Object reference not set to an instance of an object.” If someone has an example of a script that works in there environment they can share I can see if I am doing something wrong.

How to analyze the ram and cpu occupation of a virtual machine on NUTANIX over a period.

HelloI would like to use REST API within Prism Central to assign a category to a VM.I dont know how to do thatDo I need to use this API - “Update an existing VM” (put /vms/{uuid})or this API- “Create or Update a category value” (put /categories/{name}/{value})And how can I use it to assign a new category and not remove previous category ?RegardsPascal   

Hi everyone,WEe are in AOS 5.20 (up to date) and because there is a problem, I need to configure some VM that are set with non english keyboard layout through the nutanix console, bu I can’t. it seems console only know english layout. Is there any to use non-english layout ?or should I fill a bug/feature request ?

Hi, I know in last few days that by default, storage in AHV is thinly provisioned. So, im asking if there is a way to avoid disk over-provisioning ? 

Similarly to a CVM, Prism Central VM can run out of space.There are three main contributors:localhost_access_log.txt not being rotated properly Nutanix Insights collector log file have consumed more disk space than expected on Prism Central and Controller VMs multiple Nutanix Guest Tool installers are stored in the home directory of Prism CentralWhile the engineering team is working on improving the product behaviour, there are some things you can do about preventing a PC failure:Log in to the PC VM. Navigate to the /home partition List the contents of the directory by size and look for any large unused files that can be deleted.Some common sub-directories under /home where large files are likely to be found. Files in these locations can be deleted to free up space.   Delete the files in the folder but NOT the folder itself./home/nutanix/software_downloads/ - Delete any old versions other than the versions you are currently upgrading /home/nutanix/software_uncompressed/ - Delete any ol

We created a playbook to send email whenever a New VM got created in Nutanix AHV cluster. How can we add User Name and Cluster Name in Email Message? There is not much benefit if,  such details can not be provided,Event:Action: 

New IDP Enter Configuration Manually missing.It seems we are no longer able to edit or manually configure an IDP.  Has anyone come across this with newer versions of Prism Central? 

Hallo people, i'm new here and new in the theme nutanix ce. We have three servers in a cluster. All the systems are ok. I mean it is the version PRISM central 5.6 but i'm not sure, because i don't find the version number on dashboard... Now i want to upload an iso image from my workstation to nutanix ce. But something goes wrong and the nutanix tell me this: openSUSE-Leap-15.0-NET-x86_64.iso: { "api_version": "3.1", "code": 500, "message_list": [ { "message": "Internal Server Error. Failed to stream image: {\n \"api_version\": \"3.1\",\n \"code\": 500,\n \"message_list\": [\n {\n \"message\": \"Internal Server Error. No storage container found\",\n \"reason\": \"INTERNAL_ERROR\"\n }\n ],\n \"state\": \"ERROR\"\n}", "reason": "INTERNAL_ERROR" } ], "state": "ERROR" } I don't know how to assign a storage container for uploading... Anybody a tipp for me? Thank you Greetings Stephan

We have set up the connection to our Active Directory for authenticating in Prism Central. We have several clusters connected to our Prism Central. We have a scenario we are wondering about. Is it possible to restrict user access to only specific clusters in Prism Central? For example, I have user 1 and user 2 with clusters A, B, C and D in Prism Central. I want user 1 to be able to manage clusters A and C from Prism Central but want to continue to allow user 2 to be able to manage all of the clusters in Prism Central. We would want to allow user A to work with VMs only on clusters A and C and prevent access to VMs on clusters B and D. Is this possible? Currently the users in our "user 1 role" access the individual Prism Elements for the specific clusters, but we want to be able to allow our "user 1" to have a single point of access for each cluster they are meant to manage without granting them access to the other clusters in Prism Central.

What is the maximum and the minimum time range that we can establish in an analysis chart?The question surges because we need the analytical info about  some VMs but we can´t retrieve more than 3 months and we need about 18 months.

Hello, I have two questions regarding snapshot on nutanix.If I restore VM / storage using nutanix snapshot, the VM / storage still pointing the VM / storage on protection domain or not ?  What happen if the VM / storage I create earlier using nutanix snapshot when the protection domain and VM / storage removed or accidentally delete ?  Thanks,Tirtayudha

Hi, I seem to be having a problem deploying Prism Central using the automated deployment. Everything seems to go through fine, the VM is created however the install task always fails. Looking at the Prism Central VM, it seems the httpd service cannot start up, with the error: code:Redirecting to /bin/systemctl status httpd.service● httpd.service - The Apache HTTP Server Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled; vendor preset: disabled) Active: failed (Result: exit-code) since Mon 2018-10-08 00:59:43 PDT; 1min 34s ago Docs: man:httpd(8) man:apachectl(8) Process: 5495 ExecStop=/bin/kill -WINCH ${MAINPID} (code=exited, status=1/FAILURE) Process: 5493 ExecStart=/usr/sbin/httpd $OPTIONS -DFOREGROUND (code=exited, status=1/FAILURE) Main PID: 5493 (code=exited, status=1/FAILURE)Oct 08 00:59:43 ntnx-192-168-4-59-a-cvm systemd[1]: Starting The Apache HTTP Server...Oct 08 00:59:43 ntnx-192-168-4-59-a-cvm httpd[5493]: [Mon Oct 08 00:59:43.868554

I would like to download the cluster info file so I can apply licenses to my prism element over CLI. I can do this interactively by opening an SSH command and it asks if I am sure [y/N]. When automating this, how do I go about entering “y”? I usually get around this by using -echo 'y' | ncli license download-cluster-info file-path='/home/nutanix/cluster_name.csf' But its not liking it -nutanix@NTNX-20FM5A210030-A-CVM:10.248.8.62:~$ echo 'y' | ncli license download-cluster-info file-path='/home/nutanix/L02VM1.csf'This operation will start the licensing process. Are you sure you want to proceed (y/N)?: Error: null 

Hey all, I´m looking for a way to filter out all VMs that need an guest tools upgrade in PC.I tried:VMs "VM Type"="User VM" "Installed Version"="Upgrade available" ListorVMs "VM Type"="User VM" "NGT Status"="Upgrade available" List as a filter but that´s not working. I was able the list all VMs with tools installed with this filter:VMs "Nutanix Guest Tools"=Installed "VM Type"="User VM" List PC Version: pc.2021.7PE Version: 5.20.1.1 LTS Thanks in advanceErik

Hi All,  Just wondering is there anyway to find the uptime of a virtual machine running on AHV?

Hello People, Facing strange issues on deploying Nutanix 3 node cluster. Everything is completed without any issues deploying Nutanix. After restarted the nodes we are not able to reach AHV Node IPs after logging into ILO manually restarted the network services and then the AHV and CVM are reachable and all the cluster is normal. These happen only I restarted the nodes or shutting down AHV.Before restarting, network interfaces are up only.   From Switch side we have configured access port VLAN tagged 1010.  Here eth4 is connected on switch-1 port 1 and same eth6 is connected on switch-2 port 2  Note : Both switch-1 and switch-2 is stacked  Model : Cisco SG350XG  AOS : 5.20.1.1 LTSHere my config nutanix@NTNX-CVM:101.101.0.13:~$ allssh manage_ovs show_uplinks================== 101.101.0.14 =================Bridge: br0  Bond: br0-up    bond_mode: active-backup    interfaces: eth6 eth4    lacp: off    lacp-fallback: false    lacp_speed: slow================== 101.101.0.15 =================

Currently running PrismCentral pc.2021.3.0.2After upgrading to this version, the /home partition is supposed to expand to 50gb from 40gb.  This unfortunately did not happen.I found KB9525, and tried to run this command to manually expand the partition:sudo python /usr/local/nutanix/bootstrap/bin/pc_config_home_partition.py --skip_end_sector_validationThat didn’t succeed in expanding the /home partition (which was sitting at 91% utilisation)In the pc_config_home_partition.log file, I found this error::178 BLKRRPART: Device or resource busysfdisk: The command to re-read the partition table failed.Run partprobe(8), kpartx(8) or reboot your system now, before using mkfsI ran partprobe, didn’t helpkpartx requires parameters, and I wasnt sure what inputs to provide, so I didn’t run thatI did reboot Prism Central, but that didn’t help either, except it did somehow reduce disk utilisation of /home to 76% from 91%.  Still couldn’t expand the disk thoughAnyone faced a similar situation, or have

Hey folks,I have created an Alerts dashboard for a cluster. The project is meant to be an enhancement to the Analysis page in Prism in terms of data visualization. You get a single page view of the alert stats generated in your cluster.https://github.com/nkunnath/dash-alerts-ntnx Please feel free to try it out and let me know if this has been useful. Any suggestions/improvements/ideas are welcome.  Cheers!

Hi everyone,I want change current CVM memory size from 32GB to 40GB (AOS 5.15, NX model)but when I select Configure CVM in the Setting page,there is no option for 40GB from dropbox (only 36GB, 48GB and 64Gb)But when I checked on other Nutanix cluster (AOS 5.20, HX Model)I can choice 40GB from dropbox.So is it behavior change from 5.15 to 5.20? or It depends on Hardware model (NX vs DX)Ref URL: CVM Memory ConfigurationAnd if I want to change CVM memory to 40GB, I must using CLI?

Prism Central pc.2021.5 added the ‘Resiliency Status’ to the Storage widget which is a cool idea. However all of my PE clusters in this widget show as Unknown with a callout that reads “Details are unavailable in Clusters < 6.0”.Looking at the latest downloads available online I do see a version 6.0 of AOS for the STS release path so I assume that we’ll have a wait a little while longer for us LTS customers.  

In case you have to configure a snapshot frequency for a business critical application that can sustain a maximum of 40 min of data loss, is it better to configure the snapshot frequency of the protection domain at 15min or is it better to set a 30min frequency?

Do you still wonder which one to use Number of vCPU or Number of Cores per Socket when configuring a VM? You read something about it and it makes sense and you think you will now remember only to stumble upon the same dilemma sometime later. Shall we clear this once and for all?   vCPU and cores are inherently bound to a NUMA node which, in essence, is as a processor with direct attached memory. Under some (but not all) conditions, accessing memory or devices across NUMA boundaries will result in decreased performance. Hence the goal is to configure a VM with CPU and memory values that remain within the boundaries of a single NUMA node. The exception would be a NUMA-aware application. Another thing to remember is that hot add of the number of cores is not supported on AHV meaning adjustment of number of cores value for a VM requires the VM to be a powered off.   To ensure optimal performance of the VMs in the cluster follow simple rules: Use vCPUs instead of cores to increase the

Hi Team,We could see multiple alerts are getting triggered for the "cluster_IOPS" as mentioned below and kindly assist us on it to resolve it . Alert: QOS_NUTANIX_CLUSTER_IOPS = 5619.0 on XXXX has crossed the informational static threshold of >3000.0
