The network panel in ESXTOP has a few metrics that will enable you to determine issues such as loss of network on a VM or high dropped packet on specific nics. Below is simple overview on how to use esxtop for networking: How to access:Log into your ESXi host and type esxtopPress ‘n’ to show only the networking view  Port ID - The port ID used on the virtual switch. This ID is used for example for network traces with pktcap-uw.Press 'N' to sort by PORT-ID column.USED-BY - Indicates what is connected to the virtual switch port. Connected devices can be virtual machine NICs, VMkernel ports (vmk#), physical NICs (vmnic#) or ports used for health checks (Shadow of vmnic#).TEAM-PNIC - The physical NIC that the corresponding device is actively using. This information is helpful for network troubleshooting.%DRPTX - Dropped packets transmitted,  hardware overworked. Possible cause : very high network utilization.%DRPRX - Dropped packets received, hardware overworked. Possible cause : very high

I am using the newest version of X-ray (3.10.0) to connect to a vCenter (6.5U1d) to have some performance tests for my cluster. At the step 4 (Validation) of creating the target cluster, it failed to validate the cluster.Error: Target cannot be verified.After looking into the log, in the HTTP Response body, it contains the 500 Internal Server Error. Still cannot get what it means as everything seems fine and the connection from X-ray VM to cluster still has no problem at all.

Is there support for Cloudstack and Nutanix or drives for it to run.

I’m relatively new to Powershell and have been looking for the cmdlet get the Role Mapping information from a cluster. I’ve no issues connecting using Powershell I just cant find the correct cmdlet which will allow me to get the Role Mappings. My apologies if I haven’t placed this is the correct group.

As part of the Nutanix Smart Support, information about dispatches can now be viewed directly from Portal. With this view, you can edit Shipping, Contact, or FE work address details if necessary.Additional information such as the Part Type, Quantity, Part Location/Component Slot are all viewed from the same pane.If you need more clarification on the dispatch specifically, a Comment option is in place to reach out to Nutanix Support directly. These comments will also be placed in the case notes to look back at if necessary.For more information about the dispatch view, take a look at Dispatches Summary View on the Support Portal.

When migrating Windows VMs from AWS into a Nutanix cluster and while using automatic Windows VM preparation, it is important to verify permissions configurations in two places within AWS. Specifically, the permissions for the AWS account that is provided when adding an AWS source into Move and the permissions of the IAM profile associated with the VM instance to be migrated. AWS allows permissions configurations to be viewed/updated in a JSON format. Further, the Move User Guide also lists the necessary permissions for these entities in a JSON format. These JSON values can then be reviewed/compared and, if any of the permissions are missing or configured incorrectly from AWS, simply update the permissions according to the User Guide values. Also, it should be verified that the Windows VM instance is properly managed by the AWS SSM Manager prior to a migration attempt. Further information regarding this can be found within the AWS to Nutanix Clusters on AWS and AHV VM Migration section

There are times, when we need to move a vm disk to a different container on the same AHV Cluster.For e.g. : We may want to move this VM Disk on a container with De-Dupliction Disabled. To relocate a virtual machine’s disk to a different container on the same AHV cluster, following steps are required:Requirements for the Move:Source Container ID (where the vmdisk is located originally) Destination Container ID (our target container on the same cluster) VM Disk(s) UUID (UUID of each disk we need to move “acli vm.get <vm-name>”) Power-off the VMSummary of Steps:Determine the vmdisk_uuid of each virtual disk on the VM. Make sure the VM for which the VMdisk we are migrating is powered off. Use the Acropolis Image Service to clone the source Virtual Disk(s) into Image(s) on the target container. Attach the disk from the Acropolis Image(s) which created in Step 3 to the VM. Remove the VM disk that is hosted on the original container Optional: Remove the cloned VMdisk from image services

The storage usage reaches 95% and some windows VM (2016 2019)down.AHV hypervisor 20170830.395After release the disk space many VMs should be repaired.Questions:AHV will shut down VM when the capacity reaches 95% ?  If user reboot VM when it is 95% , will it make  the VM data disks crashed ?

Did you know that Nutanix now has a Smart Support diagnostics collection feature available in Nutanix Support Portal which can directly initiate log collection on Nutanix clusters thereby avoiding the need to manually collect and upload logs to the case?Customers can create a diagnostics collection for any of their clusters on demand. A diagnostics collection is a set of logs and health checks collected in a cluster for a specified interval. They are resources used to monitor the health of the clusters and analyze issues when problems occur. For details on how to create a new diagnostics collection via Nutanix Support Portal, see Creating a Collection section in Nutanix Support Portal. 

I have read the documents and manuals of APC PowerChute Network but it is a scenario that doesn’t apply to mean. Apparently, someone sold to the customer a Vertiv Liebert GXT4 UPS. Liebert’s engineers concluded that the product couldn’t provide a graceful shutdown of the Nutanix cluster, while it could shutdown the ESXi on top.Is there anyone out there who had succeeded in performing a graceful shutdown without APC?

We have Nutanix SX-1065-G5 with 3 nodes, every node have 4*16GB, and we need to add 64GB to every node. Is it possible to add 4*16GB for every node ?RAM : C-MEM-16GB-DDR4-2400 

We are planning to add new nodes to existing clusters.Before the extension, proceed with the new Node AOS install (Bare metal image) and then add.At this time, I want to know if there is no problem if the existing cluster AOS and the new AOS are different versions.ex) Existing Cluster AOS 5.10.9 / New Extension Node AOS 5.15.xPlease give me some advice.Thank you.

vCenter 7.0U1c and vSphere Clustering Service VMs on local or shared storage.After test upgrading vCenter from 6.5U3 to 7.0U1c (which worked just fine w 0 issues), every vmware cluster with DRS and/or HA enabled gets 3 new vCLS (very tiny VMs w 2GB storage/.13GB RAM).When NCC is ran it registers 3 WARNs that there are VMs running on the SATADOM’s. I would assume that, even what (little) they do (today), would this wear out Satadom’s or M.2’s?Would this be a concern for G4/G5’s (w Satadoms) and not G6/G7’s (M.2’s)?”While vCLS can be moved to shared storage, wouldn’t they be moved back to local storage during an NX cluster stop?(Like to point out this was done in a LAB environment, not in Production… no bits nor bytes were harmed during the upgrade progress.)

ESXTOP can be very good to tool to see the live stats and usage of the Physical host and its components, but more often than not, we would like to use that data to plot graphs or even save the data to examine it later. This brings us to the most important use case of ESXTOP is to run ESXi in batch mode. Batch mode provides us a way to collect esxtop stats from a physical ESXi host and analyze it on a Windows machine using Perfmon. Capture the Data:First thing would be capture only the relevant info and omit all the metrics you don't need.Use ‘f’ to ADD/Remove FieldsUse ‘o’ to change the order of Metrics Use ‘W’ to save the settings that you just edited.Caution: If you don't input a file name, the default settings will be saved as such. We are ready to run the esxtop in batch mode. esxtop -b -d 2 -n 100 > esxtop.csv b=batch moded=delayn=No of Iterationsa=all Metrics Usually capturing esxtop for an extended period of time can result in a large file. In order to avoid this, we can zip

I’d like to rename the host name on a single-node cluster - assuming that I update the name in the /etc/sysconfig/network and /etc/hostname files, I guess I would also need to stop/start the acropolis service. I know this is safe to do on a 3-node cluster but is there are risk/impact with a 1-node cluster?

Hello,I was hoping to get some clarification as to what features are included in AOS Starter.  I usually use the following link as a guide:Nutanix Software Editions & Licensing: Solutions to Run on Our AppliancesThe above link states that “Basic Compression (LZ4) - Inline and post process” are included starter.  However as soon as I enable post compression I get a license violation notice.  In prism element it also shows the available features for starter and post compressions shows as yes:Is post compression available in Starter? Also the link states that lz4hc compression is not available for Starter but running the following command on a starter clusters show it is available and compressing data:curator_cli display_data_reduction_report Has something changed to make lz4hc available to starter? Is there another document or link with a comprehensive list of features available for each edition? Thanks,--Zip
