Configure GigaVUE Fabric Components in AWS

This section provides step-by-step information on how to register GigaVUE fabric components using AWS EC2 or a configuration file.

Keep in mind the following when deploying the fabric components using generic mode:

  • Ensure that the Traffic Acquisition Tunnel MTU is set to the default value of 8590. To edit the Traffic Acquisition Tunnel MTU, select the monitoring domain and click on the Edit Monitoring Domain option. Enter the Traffic Acquisition Tunnel MTU value and click Save.
  • Before deploying the monitoring session ensure that the appropriate Traffic Acquisition Tunnel MTU value is set. Otherwise, the monitoring session must be un-deployed and deployed again.
  • When deploying the fabric components using generic mode, the connection name must be used as the subGroupName in the registration data.
  • You can also create a monitoring domain under Third Party Orchestration and provide the monitoring domain name and the connection name as groupName and subGroupName in the registration data. Refer to Create Monitoring Domain for more detailed information on how to create monitoring domain under third party orchestration.
  • Only G-vTAP and Customer Orchestrated Source can be used as the traffic acquisition method when using generic mode.
  • When you deploy the fabric components using third party orchestration, you cannot delete the monitoring domain without unregistering the registered fabric components.
  • GigaVUE V Series Node must have a minimum of two Networks Interfaces (NIC) attached to it, a management NIC and a data NIC. You can add both these interfaces when deploying the GigaVUE V Series Node in AWS. Refer to Launch an instance using the Launch Instance Wizard topic in Amazon EC2 Documentation for more detailed information on how to add network interfaces when launching an instance.

In your AWS EC2, you can configure the following GigaVUE fabric components:

Configure G-vTAP Controller in AWS

You can configure more than one G-vTAP Controller in a monitoring domain.

To register G-vTAP Controller in AWS EC2, use any one of the following methods:

Register G-vTAP Controller during Instance Launch

In your AWS EC2 portal, to launch the G-vTAP Controller AMI instance and register G-vTAP Controller using user data, follow the steps given below:

  1. On the Instances page of AWS EC2, click Launch instances. The Launch Instance wizard appears. For detailed information, refer to Launch an instance using the Launch Instance Wizard topic in Amazon EC2 Documentation.
  2. On the Step 3: Configure Instance Details tab, enter the User data as text in the following format and deploy the instance. The G-vTAP Controller 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>
            subGroupName: <Connection Name>
            user: <Username>
            password: <Password>
            remoteIP: <IP address of the GigaVUE-FM>
            remotePort: 443
  3. You can navigate to Instances > Actions > Instance Settings > Edit user data and edit the user data.

The G-vTAP Controller deployed in AWS EC2 appears on the Monitoring Domain page of GigaVUE-FM.

Register G-vTAP Controller after Instance Launch

To register G-vTAP Controller after launching a Virtual Machine using a configuration file, follow the steps given below:

  1. Log in to the G-vTAP 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 G-vTAP Controller service.
    $ sudo service gvtap-cntlr restart

The deployed G-vTAP Controller registers with the GigaVUE-FM. After successful registration the G-vTAP 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 G-vTAP Controller and if that fails as well then GigaVUE‑FM unregisters the G-vTAP Controller and it will be removed from GigaVUE‑FM.

Configure G-vTAP Agent in AWS

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

G-vTAP Agent should be registered via the registered G-vTAP Controller and communicates through PORT 8891.

To register G-vTAP Agent in AWS, use any one of the following methods.

Register G-vTAP Agent during Instance Launch

Note:  Registering G-vTAP Agent during Virtual Machine Launch is not applicable for Windows Agents. You can register your Windows Agents after launching the Virtual machine, using a configuration file.

In your AWS EC2, to launch the G-vTAP Agent AMI instance and register the G-vTAP Agent using user data, follow the steps given below:

  1. On the Instances page of AWS EC2, click Launch instances. The Launch Instance wizard appears. For detailed information, refer to Launch an instance using the Launch Instance Wizard topic in Amazon EC2 Documentation.
  2. On the Step 3: Configure Instance Details tab, enter the User data as text in the following format and deploy the instance. The G-vTAP Agent 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>
             subGroupName: <Connection Name>
             user: <Username>
             password: <Password>
             remoteIP: <IP address of the G-vTAP Controller 1>, <IP address of the G-vTAP Controller 2>
             remotePort: 8891

  3. You can navigate to Instances > Actions > Instance Settings > Edit user data and edit the user data.

Register G-vTAP Agent after Instance Launch

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

To register G-vTAP Agent after launching a Virtual Machine using a configuration file, follow the steps given below:

  1. Install the G-vTAP Agent in the Linux or Windows platform. For detailed instructions, refer to Linux G-vTAP Agent Installation and Windows G-vTAP Agent Installation.

  2. Log in to the G-vTAP Agent.
  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\gvtap-agent\gigamon-cloud.conf is the local configuration file in Windows platform.
    Copy
    Registration:
        groupName: <Monitoring Domain Name>
        subGroupName: <Connection Name>
        user: <Username>
        password: <Password>
        remoteIP: <IP address of the G-vTAP Controller 1>, <IP address of the G-vTAP Controller 2>
        remotePort: 8891

    User and Password must be configured in the User Management page. Refer to Configure Role-Based Access for Third Party Orchestration for more detailed information. Enter the UserName and Password created in the Add Users Section.

  4. Restart the G-vTAP Agent service.
    • Linux platform: 
      $ sudo service gvtap-agent restart
    • Windows platform: Restart from the Task Manager.

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

Configure GigaVUE V Series Nodes and V Series Proxy in AWS

Note:  It is not mandatory to register GigaVUE V Series Nodes via V Series proxy however, if there is a large number of nodes connected to GigaVUE-FM or if the user does not wish to reveal the IP addresses of the nodes, then you can register your nodes using GigaVUE V Series Proxy. In this case, GigaVUE-FM communicates with GigaVUE V Series Proxy to manage the GigaVUE V Series Nodes.

To register GigaVUE V Series Node and GigaVUE V Series Proxy in AWS EC2, use any one of the following methods.

Register GigaVUE V Series Node and GigaVUE V Series Proxy during Instance Launch

  1. On the Instances page of AWS EC2, click Launch instances. The Launch Instance wizard appears. For detailed information, refer to Launch an instance using the Launch Instance Wizard topic in Amazon EC2 Documentation.
  2. On the Step 3: Configure Instance Details tab, enter the User data as text in the following format and deploy the instance. The GigaVUE V Series Nodes or V Series proxy 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>
            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>.
    • User and Password must be configured in the User Management page. Refer to Configure Role-Based Access for Third Party Orchestration for more detailed information. Enter the UserName and Password created in the Add Users Section.
    You can navigate to Instances > Actions > Instance Settings > Edit user data and edit the user data.

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

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

  1. Log in to the GigaVUE V Series Node or Proxy.
  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> or <IP address of the proxy>
        remotePort: 443
    • 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>.

    • User and Password must be configured in the User Management page. Refer to Configure Role-Based Access for Third Party Orchestration for more detailed information. Enter the UserName and Password created in the Add Users Section.

  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 the GigaVUE 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 the GigaVUE V Series proxy and it will be removed from GigaVUE‑FM.

Note:  When the GigaVUE V Series Node is stopped or terminated from the AWS, it does not send any unregistration request and GigaVUE-FM will unregister the V Series Node soon after.

Keep in mind the following when upgrading the GigaVUE-FM to 6.1.00 (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 that 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.
