The UCT-V Controller deployed in Nutanix appears on the Monitoring Domain page of GigaVUE-FM.

Register UCT-V Controller after Instance Launch

To register UCT-V Controller after launching a Virtual Machine using a configuration file, perform the following steps:

  1. Log in to the UCT-V Controller.
  2. Create a local configuration file (/etc/gigamon-cloud.conf) and enter the following user data.
    Copy
    Registration:
        groupName: <Monitoring Domain Name>
        subGroupName: <Connection Name>
        user: <Username>
        password: <Password>
        remoteIP: <IP address of the GigaVUE-FM>
        remotePort: 443
  3. Restart the UCT-V Controller service.
    $ sudo service uctv-cntlr restart

Assign Static IP address for UCT-V Controller

By default, the UCT-V Controller gets assigned an IP address using DHCP. If you wish to assign a static IP address, follow the steps below:

  1. Navigate to /etc/netplan/ directory.
  2. Create a new .yaml file. (Other than the default 50-cloud-init.yaml file)
  3. Update the file as shown in the following sample:
    Copy
    network:
            version: 2
            renderer: networkd
            ethernets:
                    ens3:
                            addresses:
                                    - <IP address>
                            gateway: <IP address>
                    ens4:
                            addresses:
                                    - <IP address>
                            gateway: <IP address>
                    ens5:
                            addresses:
                                    - <IP address>
                            gateway: <IP address>
  4. Save the file.
  5. Restart theUCT-V Controller service.

    $ sudo service uctv-cntlr restart

The deployed UCT-V Controller registers with the GigaVUE-FM. After successful registration the UCT-V Controller sends heartbeat messages to GigaVUE-FM every 30 seconds. If one heartbeat is missing ,the fabric node status appears as 'Unhealthy'. If more than five heartbeats fail to reach GigaVUE-FM, GigaVUE‑FM tries to reach the UCT-V Controller and if that fails as well then GigaVUE‑FM unregisters the UCT-V Controller and it will be removed from GigaVUE‑FM.

Note:  When you deploy GigaVUE V Series Nodes or UCT-V Controllers using 3rd party orchestration, you cannot delete the monitoring domain without unregistering the GigaVUE V Series Nodes or UCT-V Controllers.

Configure UCT-V in Nutanix

Note:  Deployment of GigaVUE fabric components through a third-party orchestrator is supported on Linux and Windows platforms. Refer to Linux UCT-V Installation and Windows UCT-V Installation for detailed information.

UCT-V should be registered using the registered UCT-V Controller. It uses PORT 8891.

To register UCT-V in Nutanix, you can use any one of the following methods.

Register UCT-V during Instance Launch

Note:  Registering UCT-V during Virtual Machine Launch is not applicable for Windows Agents. You can register the Windows Agent after launching the Virtual machine using a configuration file. The configuration file is located in C:\ProgramData\uctv\gigamon-cloud.conf

In Nutanix Prism Central, to launch the UCT-V instance and register the UCT-V using user data, perform the following steps:

  1. On the Prism Central, go to the List tab and click Create VM. The Create VM dialogue box appears. For detailed information, refer to Creating a VM through Prism Central (AHV) topic in Nutanix Documentation.
  2. On the Step 3:Management tab, in the Guest Customization field, select Cloud-init (Linux). Enter the registration data in the text box and deploy the instance. The UCT-V uses this user data to generate config file (/etc/gigamon-cloud.conf) used to register with GigaVUE-FM.
    Copy
    #cloud-config
     write_files:
     - path: /etc/gigamon-cloud.conf
       owner: root:root
       permissions: '0644'
       content: |
         Registration:
             groupName: <Monitoring Domain Name>

             remoteIP: <IP address of the UCT-V Controller 1>, <IP address of the UCT-V Controller 2>
             remotePort: 8891

Register UCT-V after Instance Launch

Note:  You can configure more than one UCT-V Controller for a UCT-V, so that if one UCT-V Controller goes down, the UCT-V registration will happen through another Controller that is active.

To register UCT-V after launching a Virtual Machine using a configuration file, perform the following steps:

  1. Install the UCT-V in the Linux or Windows platform. For detailed instructions, refer to Linux UCT-V Installation and Windows UCT-V Installation.

  2. Log in to the UCT-V.
  3. Create a local configuration file and enter the following user data.
    • /etc/gigamon-cloud.conf is the local configuration file in Linux platform.
    • C:\ProgramData\uctv\gigamon-cloud.conf is the local configuration file in Windows platform.
    • When creating C:\ProgramData\uctv\gigamon-cloud.conf file, ensure that the file name extension is .conf. To view the file name extension in Windows, follow the steps given below:
      1. Go to File Explorer and open the File Location.
      2. On the top navigation bar, click View.
      3. In the View tab, enable the File name extensions check box.

    Copy
    Registration:
        groupName: <Monitoring Domain Name>
        subGroupName: <Connection Name>
        user: <Username>
        password: <Password>
        remoteIP: <IP address of the UCT -V Controller 1>,<IP address of the UCT -V Controller 2>
        remotePort: 8891
  4. Restart the UCT-V service.
    • Linux platform: 
      $ sudo service uctv restart
    • Windows platform: Restart from the Task Manager.

The deployed UCT-V registers with the GigaVUE-FM through the UCT-V Controller. After successful registration the UCT-V sends heartbeat messages to GigaVUE-FM every 30 seconds. If one heartbeat is missing, UCT-V status appears as 'Unhealthy'. If more than five heartbeats fail to reach GigaVUE-FM, GigaVUE‑FM tries to reach the UCT-V and if that fails as well then GigaVUE‑FM unregisters the UCT-V and it will be removed from GigaVUE‑FM.

Configure GigaVUE V Series Nodes and V Series Proxy in Nutanix

Note:  It is not mandatory to register GigaVUE V Series Nodes using the V Series proxy. However, if there are large number of nodes connected to GigaVUE-FM or if you want to hide the IP addresses of the nodes, then you can register the nodes using GigaVUE V Series Proxy. In this case, GigaVUE-FM communicates with GigaVUE V Series Proxy to manage the GigaVUE V Series Nodes.

Note:  Before deploying V Series Node, enable the Multi Queue. For more information on enabling the multi-queue, refer to the Nutanix KB article How to change number of vNIC queues and enable RSS virtio-net Multi-Queue for AHV VMs. You can enable the Multi Queue using the Nutanix REST APIs. For more infomation on Nutanix APIs, refer to Nutanix support site.

    • You can register your GigaVUE V Series Nodes directly with GigaVUE‑FM or you can use GigaVUE V Series Proxy to register your GigaVUE V Series Nodes with GigaVUE‑FM. If you wish to register GigaVUE V Series Nodes directly, enter the remotePort value as 443 and the remoteIP as <IP address of the GigaVUE‑FM> or if you wish to deploy GigaVUE V Series Nodes using V Series proxy then, enter the remotePort value as 8891 and remoteIP as <IP address of the Proxy>.

Register GigaVUE V Series Node and GigaVUE V SeriesProxy after Instance Launch

To register GigaVUE V Series Node and GigaVUE V Series Proxy after launching the virtual machine using a configuration file, perform the following steps:

  1. Log in to the GigaVUE V Series Node or Proxy.
  2. Edit the local configuration file (/etc/gigamon-cloud.conf) and enter the following user data.
    Copy
    Registration:
        groupName: <Monitoring Domain Name>
        subGroupName: <Connection Name>
        user: <Username>
        password: <Password>
        remoteIP: <IP address of the GigaVUE-FM> or <IP address of the Proxy>
        remotePort: 443
    • You can register your GigaVUE V Series Nodes directly with GigaVUE‑FM or you can use V Series proxy to register your GigaVUE V Series Nodes with GigaVUE‑FM. If you wish to register GigaVUE V Series Nodes directly, enter the remotePort value as 443 and the remoteIP as <IP address of the GigaVUE‑FM> or if you wish to deploy GigaVUE V Series Nodes using V Series proxy then, enter the remotePort value as 8891 and remoteIP as <IP address of the Proxy>.
  3. Restart the GigaVUE V Series node or proxy service. 
    • V Series node: 
      $ sudo service vseries-node restart
    • V Series proxy: 
      $ sudo service vps restart

The deployed GigaVUE V Series proxy registers with the GigaVUE-FM. After successful registration theGigaVUE V Series proxy sends heartbeat messages to GigaVUE-FM every 30 seconds. If one heartbeat is missing, the fabric node status appears as 'Unhealthy'. If more than five heartbeats fail to reach GigaVUE-FM, GigaVUE‑FM tries to reach the GigaVUE V Series proxy and if that fails as well then GigaVUE‑FM unregisters theGigaVUE V Series proxy and it will be removed from GigaVUE‑FM.

Keep in mind the following when upgrading the GigaVUE-FM to 6.1.00 or higher version (when using third party orchestration to deploy fabric components):

When upgrading GigaVUE-FM to any version higher than 6.0.00 and if the GigaVUE V Series Nodes version deployed in that GigaVUE-FM are lower than or equal to 6.0.00, then for the seamless flow of traffic, GigaVUE-FM automatically creates Users and Roles in GigaVUE-FM with the required permission. The username would be orchestration and the password would be orchestration123A! for the user created in GigaVUE-FM. Ensure there is no existing user in GigaVUE-FM, with the username orchestration.

It is recommended to change the password in the Users page, once the upgrade is complete. Refer to Configure Role-Based Access for Third Party Orchestration for detailed steps on how to change password in the user page.
