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 Fields

I’m seeing:Detailed information for garbage_egroups_size_check:Node 10.1.11.32:FAIL: 67% of disk 415104829 occupied by garbage egroupsRefer to KB 1574 (http://portal.nutanix.com/kb/1574) for details on garbage_egroups_size_check or Recheck with: ncc health_checks stargate_checks garbage_egroups_size_checkon 2019.02.11 LTSDisk 415104829 (SSD) was added yesterday. I also added one ssd to 2 nodes tonight. The new ssd’s are very busy right now.

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 compres

As i know that if drive failure, Nutanix will rebuilt the data immediately. May i know if node failure, how long does the Nutanix will trigger to rebuilt if have sufficient node and capacity in existing cluster? Thanks

There are instances when you have to perform a rolling restart of the CVMs (Controller VMs) or a rolling restart of the hypervisor hosts or a restart of just one of the CVMs. This is a list of health checks to execute prior to the restart to verify cluster health. Verify if any nodes or services are in a 'down' state. Run the following command for smaller sized clusters: nutanix@cvm$ cluster status If the cluster contains multiple nodes, running the following command which excludes services that are UP from the output may be more convenient:nutanix@cvm$ cluster status | grep -v UPNodes or services that are unexpectedly in a 'down' state need to be fixed before proceeding with the restart.  Verify if any nodes are missing or are in a 'down' state in the Cassandra ring. There should be the same number of nodes as the number of IPs in the svmips output (four no

LCM 2.4 introduced a new protocol called the Redfish Protocol. It uses a RESTful API interface for server management. While there are many improvements introduced in the backend, there are a couple of improvements done on the frontend as well.The main improvement on the frontend is that LCM now performs the BMC and BIOS updates using Redfish twice as fast as the older method of using a Phoenix ISO. The time gained is due to fewer restarts needed for BMC and BIOS (no restarts needed for BMC updates and one restart for BIOS updates).While there are specific requirements for LCM to utilize the Redfish protocol, the LCM UI in LCM 2.4 displays this information in the Inventory Pane.For more information about the requirements and the LCM UI, take a look at the Redfish Protocol documentation on the

Added 9 nodes(AHV) to existing cluster successfully and when i try to verifyLACP status with command (hostssh "ovs-appctl bond/show br0-up" | egrep "===|lacp_status") it is showing LACP status off.Steps i performed before adding the nodes to existing cluster1.Configured network on all 9 nodes2.Configured LACP on all 9 nodes Please advice.  

How many nodes we can deploy at the same time in nutanix ? Is there any limit or shall we just go ahead and deploy all the nodes at the same time ?Same query is related to cluster expansion, can we add multiple nodes at the same time in existing cluster ?Thanks

I’m new to Nutanix so bear with me if this has been asked. Is it possible to simulate a x-over cable between two VM’s? basically I want any traffic leaving a load balancer to be passed via layer 1-2 to a WAF appliance so it can be inspected. The WAF is in transparent mode and won’t have an IP Address. In the past with physical machines i would just cable them inline. 

Dear All,May I have a question about the below situation?RF=23 node cluster2 x disks failure in same nodeMay i know whether the cluster will be corrupted or not? From my understanding, it should not be corrupted as 2 x disks failure in same node (NOT different node).

Hi All,Current environment (~40 sites & HO) do not have any 10GbE switches and we are planning 2-node clusters per site. If using 2 x 1GbE Nic for the management like a witness communication, can we connect ESXi nodes using  10gbit ‘direct cable’ to support the workload for all VM traffic, vMotion, vmKernel, and Nutanix and most important, two node disks datastore? It should be not any issue for the Nutanix/VMware level, Switch is on L2.

Can I change IP or VLAN in IPMI after Foundation that will be concern or affect to AHV environment?

HiI’m using Nutanix Prism Central v3 API and I want to run the API call referenced here:https://www.nutanix.dev/reference/prism_central/v3/api/categories/postcategoryquery/to get the category information.I’m calling this API: https://<prism_ip>:9440/api/nutanix/v3/category/query, using Postman. My problem is filling the request body. The example at the bottom of the page shows this request body:{  "api_version": "3.1.0",  "group_member_count": 123,  "group_member_offset": 123,  "usage_type": "string",  "category_filter": {    "type": "CATEGORIES_MATCH_ANY",    "kind_list": [      "string"    ],    "params": {}  }} But the

HiIs there a way to check the versions of all Nutanix components in one view? “ncli cluster info” displays the AOS and NCC versions, but not those of AHV and PC. The AHV and PC versions may be obtained from the PC UI (in different places though). Further, the Nutanix release timeline shows AOS 5.18 as the latest, but the documentation has tags for 5.19?

I feel it is time to address a seemingly minor question: should you re-image your nodes when re-using them from an existing cluster? To give a better idea of a setup, think of a cluster with eight nodes, for example. You would like to scale down the cluster and re-use 4 of those nodes to form another cluster. You have evicted the nodes, and you could create a new cluster at this stage but let's take a look at the pros and cons of rushing forward.Cluster creation does no wipe the system. All the files on the nodes remain as they are when you trigger cluster creation. That sometimes can mean issues with LCM upgrades or the cluster creation may error out. To resolve those issues you would need to find those files and chances are you would need a Nutanix Support Engineer to deal with that.Some features introduced in software releases are only available if the version is a fresh installation rather than an upgrade.Any networking changes you might need are easy to appl
