Playbooks Rest API Post Teams
Im trying to create a playbook that on X alert posts to teams channel…. is this possible? I have tried a few methods but not having much joy. Method: POST URL: https://outlook.office.com/webhook/blahblahblahlongstring user: blank Pass: blank Request body: I have tried setting json and tried using the built in parameters Alert: Source Entity Name Alert: Alert Name Alert: Creation Time Alert: Severity request headers: blank or Content-Type: application/json so am i just missing something about the syntax? Or is the rest api call for nutanix api’s only? Thanks in advance.
SNMP Alerts Message Format
Recently my customer is configuring snmp monitoring in their infrastructure to monitor their nutanix clusters. As their Administrators are trying to capture keywords from the snmp traps, they found that the snmp trap messages and the alerts messages found in the web console guide are different. Is there a document which can help to indicate what are the exact snmp trap messages /format for the different alerts sent?
Failed to reach a node where Genesis is up. Retrying
Hi, A customer moved his Nutanix Cluster (with Hyper-V) from a DC to another, after powering the Nodes up, the IPs of all Hyper-V host and CMs released, I logged it locally to Hyper-V hosts and configure the internal IP (192.168.5.1/28) and the external IP same like before shutting the cluster down. I repeated the previous step with CVMs, I went through cd/etc/sysconfigs/ and edit network-scripts file and added the the external IP in the eth0 and the internal one (192.168.5.2/28) in eth1. Now Hyper-V FC is working fine but cannot start VMs due to the Nutanix cluster issue, whenever I tried to start cluster from any CVM, I get this message “WARNING genesis_utils.py:1211 Failed to reach a node where Genesis is up. Retrying” Is there any way to fix this issue or to repair cluster configuration without disrupting existing data? Thanks in advance
Issue Converting VHDX with 4K Logical sector size
We are using Image configuration to upload and convert the VHDXs and so far it works except when we attempt to upload 4K sector aligned VHDXs from an old HyperV cluster, the upload completes successfully but the conversion fails. Is it possible to migrate and convert 4K sector aligned VHDXs to a Nutanix AHV cluster? Error:

Removal of AHV Crash dump file
Hi all, A newbie question. It seems I still have an old crash dump directory on one of my AHV hosts. A ls -lahtr /var/crash shows the single directory from back in April. At the time the issue was resolved, and the faulty DIMM that was causing the issue was replaced. That said, clearly the dump file was not removed. In terms of cleaning this up, is it OK to delete the dump directory within the /var/crash directory and then rerun the ncc health check. Or is there a better method for clearing crash dumps from Nutanix clusters. Many thanks, Rob

How to Grant Prism Administrators Access to CVMs through SSH ?
Currently we are working on a project that requires couple of Admins to SSH into a CVM to execute some commands. The problem we are running into is that only the Nutanix\Admin default account can actually SSH into CVMs. Other non-default admin accounts (Cluster Admin) can do everything in Prism but are denied access when they try to SSH. Do The non-default admins need additional permissions\configurations to be able to SSH into CVMs ?
VM Guest OS was unable to get ip address from AHV
Hi Experts, Im new to Nutanix. I’d like to know why my guest OS build from my physical HP server can’t get an ip address? My physical server is connected to network however, on the created guest os, i can’t get an ipaddress from my dhcp. appreciate any help on this.
What to do when there is a DIMM failure alert?
What is the DIMM error? A memory error is an event that leads to the logical state of one or multiple bits being read differently from how they were last written. For example, If 1 was written in a memory cell and while reading the same memory cell, it returns 0. Memory errors can be classified into two types: Soft errors, which randomly corrupt bits but do not leave physical damage. Soft errors are transient in nature and are not repeatable. Soft errors can be because of electrical or magnetic interference (e.g. due to cosmic rays, alpha particles, leakage, random noise). Hard errors, which corrupt bits in a repeatable manner because of a physical/hardware defect or an environmental problem. Hard error can also occur if DIMM is not seated properly. All memory systems in use in servers today are protected by error detection and correction codes. These server machines employ error correcting codes (ECC), which allows the detection and correction of one or m
Data rebuild when CVM is down and Oplog question
Please answer the below questions : When one cvm goes down(in a 10 node cluster with RF3) for 20 mints, then Guest VM’s new write and read IO would be served by anther's CVM and all these will be traveling across 10 g network. A : Will those new IOs served from local copy via another CVM or IOs will be served from the replica copy B: Will cluster starts to build a new replica to accommodate the missing copy or RF3 Ques 2 - When new Write IO request comes, first it will write the data on Oplog then synchronously send to other CVM’s Oplog. All host in clusters having 2 SSD and 6 HDDs. Will Write IO process by both SSD in every host or only one SSD is hsving Oplog partition active at the same time ? I think there is only one oplog per CVM/host whether the host is aving all flash drive or 2 SSD and remaining HDD. But I am not sure about this statement, Please clarify..
Filter alerts via API from Prism Central
Anyone have any insights to share about using the filter option in the /alerts/list API method in Prism Central? Here is that method in the documentation: https://www.nutanix.dev/reference/prism_central/v3/api/alerts/postalertslist/ It looks like there isn’t much information available about the filter option. I have found a (very) little bit of information online about FIQL, but I have no idea what field names are available for alerts in Prism Central.

Set Project Role through API V3
Hello, I’m working with Rest API, to “automate” some operations with Ansible, trought URI Module and Jinja2. I need to create a Project, and set permission to a specific user. How can i do this with API V3? I can add user to a Project, but i can’t set the Role.. When i check trought the Web Interface, i see the user without role. Thanks!
CPU sizing - Applied weight
Hello, guys Please, help me with these two points: I’m searching for the spec int value that the sizer uses. For example, I see that a default processor is E5 2680v2, 42.31 specInt. But I searched on the website of Spec.org and I couldn’t find that and the other serverals values that use Nutanix sizer, as is shown in the picture. Maybe I search on the incorrect section of Spec.org, 2006? 2017? Please help. I was wondering if the applied weight value is published in any website of Intel. I figured out that it is a fix value: 7.3 per processor for Xeon Gold 6244, for example. I wrote down the applied weights for 3,4,5 and 6-node configuration (dual-processor) and the calculations works this way: Applied wieight in 3-node cluster: 43.8 (7.3x6) Applied wieight in 4-node cluster: 54.8(7.3x8) Applied wieight in 5-node cluster: 72.99(7.3x10) Applied wieight in 6-node cluster: 87.59(7.3x12) So I would like to know if these values (7.3 and others) are associated to the processor its

Mounting Guest tools without admin account from script?
Hi community, I’m fairly new to interacting with Nutanix for automation and was hoping my VM build task would be a simple process but I’ve hit a wall with the guest tools install. I’m building a RDS environment where I need as little human interaction as I can get to make administration easier so I’m building my host VM using SCCM. I’ve multiple good reasons for approach but its mainly in support for application deployment via happening at build time. I’ve tried to install the guest tools manually but I believe they are failing due to the files being copied from a mounted ISO which has some dynamically created certificates involved so this isn’t going to work. I can see the ISO can be mounted using the API calls but every reference I’ve seen looks to need a username/password passing in the script and I’m not overly keen in hard coding creds into script. Most of what i’ve seen is a few years old so I wondered if there has been any changes to the approach to mounting guest tools? It

W2k19 Image and cloning it for sysprep - patch monthly
I have a W2k19 VM I created as a patched image. Idea is to patch it monthly. Shut it down and clone it. Then sysprep the clone and copy the disk to the Image Service. Then I can create VM’s off of it. I will repeat the colne after patching the ~master image monthly in order to keep a patched disk ready to spin up VM’s from. We are using AHV, version 5.10. Mt question is the “CLONE” a full, independant copy of the VM ? TIA -S
