LCM Log Collection Utility

Do you know you can run a individual log collector just for LCM logs if you are having any troubles running updates from LCM?LCM (Life Cycle Manager) Log Collection Utility provides an independent script designed to collect all the important log files necessary to debug any LCM issue.The utility is available in LCM version 2.2 or later by default. It could also be used on earlier versions of LCM.Functionality:Collects LCM log files. Detects if the node is stuck in Phoenix and collects kernel logs. Collects logs for the services with which LCM interacts (Example: Foundation, Prism, etc.). The utility state is independent of such of the LCM hence it is capable of collecting logs even if the framework is down. Parses LCM configurations from Zookeeper nodes.Files/Info being collected:Node Level Information LCM leader Foundation version LCM version Hypervisor type/version LCM configuration /etc/nutanix/hardware_config.jsonFor LCM 2.3.1 and later (Automatic log collection)LCM 2.3.1 automatic

Print the size of a VM in Bytes, KiloBytes, MegaBytes and GigaBytes

Nutanix customers using AHV as their Hypervisor often need to evaluate resources being used/consumed on their infrastructure. One of those factors involved is in calculating how much space has been consumed by one or more Virtual Machines. It is possible to get granular in this scenario and be able to calculate the amount of space taken up by a VM. Depending on their environment, it should be possible or feasible for one to print out the space usage in terms of Bytes, KiloBytes, MegaBytes or GigaBytes.I have developed the following string manipulation to be able to get those numbers. Here is a sample from one of the checks I performed:nutanix@NTNX-20FM6L56789-A-CVM:172.31.1.11:~$nutanix@NTNX-20FM6L56789-A-CVM:172.31.1.11:~$ acli vm.list | grep 120-Windows-Invent120-Windows-Invent 99021293-4ea5-440a-a894-846ed07de132nutanix@NTNX-20FM6L56789-A-CVM:172.31.1.11:~$nutanix@NTNX-20FM6L56789-A-CVM:172.31.1.11:~$ acli vm.get 120-Windows-Invent | grep vmdisk_size | awk '

Analysis charts

Have you guys been utilizing the Analysis charts feature effectively? It gives you the ability to create charts that can monitor a variety of performance metrics over a week, month, or a custom time range. Here are a few ideas on how we resolved some issues seen in the field. Memory Usage (%) - Create a chart to track memory consumption or one or multiple VM’s over a time interval Hypervisor CPU Usage (%) - Measure the CPU usage of one or more hosts over time and gain a better understanding of resource constraints if any Storage Controller Latency - This is particularly useful if you suspect performance issues. Creating charts ranging to a few weeks back gives you a comparative analysis and a benchmark for the current latency observed Storage Container Usage - A classic use case for this is when multiple VM’s have been migrated out of the cluster over many days but you suspect the storage space has not been reclaimed Replication Bandwidth - Transmitted - If there are

Expanding (Scale Out) Prism Central

Do you know you can expand Prism central VM from one to three instances to support moreworkloads?If Prism Central is running on a single VM currently, you can expand it to three VMs. This increases both capacity and resiliency of Prism Central (at the cost of maintaining two additional VMs). To scale-out Prism Central instance across multiple VMs, we can follow steps below: Click Gear icon and then select Prism Central Management from Settings menu Manage Prism Central page appears which provides information about Prism Central Instance. To expand Prism Central instance from one to three VMs, click the Scale Out PC button to display the Scale Out PC page and do the following: Here are requirementswhich must be met before you can expand Prism Central or add a Prism Central VM.

Understanding Fault Domains and Rack Awareness

What is Fault Tolerance (FT)?FT is how the system ensures that both user VM data and cluster infrastructure data is protected from failure. What are Fault Domains?Failure scenarios can be thought of in terms of fault domains. There are four fault domains in a Nutanix cluster:Disk Node Block RackThis article focusses on Rack Awareness. Rack failure can occur in the following situations:All power supplies fail within a rack Top-of-rack (TOR) switch fails Network partition; where one of the racks becomes inaccessible from other racksWhen rack fault tolerance is enabled, the cluster has rack awareness and the guest VMs can continue to run with failure of one rack (RF2) or two racks (RF3). The redundant copies of guest VM data and metadata exist on other racks when one rack fails.Note – Rack fault tolerance has to be configured manually. Requirements and configuration of Rack Fault Tolerance can be found here.To learn more about Rack Fault tolerance on Nutanix Clusters click here.Now, Rack

How to configure Prism session timeout and more!

By default, the Prism Central login page includes background animation, and users are logged out automatically after being idle for 15 minutes. You can disable the background animation, change the session timeout for users, and override the session timeout completely.Some points to note:1. This setting is not persistent. In other words, if the Prism service restarts, this setting is lost and must be disabled again.2. Disabling or enabling this setting in Prism Web Console does not propagate to Prism Central or vice versa. The setting must be disabled in Prism Web Console and Prism Central UI separately.3. The timeout interval for an administrator cannot be set for longer than 1 hour. For more information on the details and steps, click here.

Rolling Reboot for CVM/Hosts

While maintaining your Nutanix environment, there is a need to apply patches to keep everything running smoothly. Some of these patches require reboot of the CVM or Hosts to take effect.For example, rebooting all hosts in a cluster means manually putting the host in maintenance mode, evacuating the VMs, turning off the CVM, rebooting the host, waiting for the CVM and host to boot up, and confirming the cluster data resiliency is OK before proceeding to the next host. As you can see, there is a lot of manual work involved.However, there is a simpler solution: leveraging the rolling reboot script. The script utilizes our shutdown token feature to ensure that the node is up and running before proceeding to the next node. If you are using AHV, the script will be available in Prism. For ESXi hypervisors and for more robust options (even for AHV), there is a command line option found in KB 4723More information about the prerequisites (please read this before using) and execution can be found

How to create key based SSH access to a cluster

key-based SSH access to a cluster is supported. Adding a key through the Prism web console provides key-based access to the cluster, Controller VM, and hypervisor host. Each node employs a public/private key pair, and the cluster is made secure by distributing and using these keys. Users can create a key pair (or multiple key pairs) and add the public keys to enable key-based SSH access. However, when site security requirements do not allow such access, you can remove all public keys to prevent SSH access. To control key-based SSH access to the cluster, do the following: Steps:Click the gear icon in the main menu and then select Cluster Lockdown in the Settings page.The Cluster Lockdown dialog box appears. Enabled public keys (if any) are listed in this window. To disable (or enable) remote login access, uncheck (check) theEnable Remote Login with Password box. Remote login access is enabled by default. To add a new public key, click the New Public Key button and then do the followin

Nutanix SCMA Implementation

The Nutanix platform and all products leverage the Security Configuration Management Automation (SCMA) framework to ensure that services are constantly inspected for variance to the security policy. Nutanix has implemented security configuration management automation (SCMA) to check multiple security entities for both Nutanix storage and AHV. It continuously assesses and heals Nutanix clusters to ensure that it meets or exceeds all regulatory requirements. In this process over 1,700 security entities are analyzed and self-corrected across storage and hypervisor (AHV only) layers. Nutanix automatically reports log inconsistencies and reverts them to the baseline.With SCMA, you can schedule the Security Technical Implementation Guides (STIG) to run hourly, daily, weekly, or monthly. STIG has the lowest system priority within the virtual storage controller, ensuring that security checks do not interfere with platform performance.To learn more about this feature, click here.

Logical Networking in Hyper-V

Networking on a Hyper-V host is very similar to networking on an AHV host and an ESXi host. Naming of objects is again different, but functionality is the same: Just like with AHV and ESXi, the hypervisor has a connection to both the InternalSwitch and the ExternalSwitch. The name of the hypervisor on a Hyper-V host is confusingly also Hyper-V, and this hypervisor attaches to virtual switches by way of a vEthernet port. All virtual network adapters are where the VLANs are defined, and also where the network names are defined. Hyper-V doesn't have port groups, it has network names which don't work at all the same way that they do in AHV. Verification Commands from Powershell Get-netadaptervmq Get-netadaptervmqQueue Please refer to this link for detail explanation of Networking in hyper-vhttps://portal.nutanix.com/page/documents/kbs/details?targetId=kA0600000008fOSCAY
