Configuring a Junos Space Virtual Appliance as a Standalone or Primary FMPM Node

You can configure a Junos Space Virtual Appliance as a Junos Space node or as a specialized network monitoring node used for fault monitoring and performance monitoring (FMPM). An FMPM node can be configured as a standalone or primary FMPM node, or as a secondary or backup FMPM node. The first FMPM node that you configure is always the standalone or primary node; this node performs fault and performance monitoring of the devices and nodes, and any events or alarms are stored in a PostgreSQL database on this node. This topic explains how you can configure a Junos Space Virtual Appliance as a primary FMPM node.

Note:

You must have at least one Junos Space node already configured to add an FMPM node in a cluster.

To configure a Junos Space Virtual Appliance as a standalone or primary FMPM node, you must configure basic network and system settings to make the node accessible on the network.

Note:

  • From Junos Space Network Management Platform Release 14.1R2 onward, you can configure Junos Space Ethernet interfaces with only IPv4 addresses, or both IPv4 and IPv6 addresses.

  • From Junos Space Network Management Platform Release 16.1R1 onward, you can configure access to Junos Space through a Network Address Translation (NAT) gateway.

Before you begin, do the following:

  • Ensure that 100 GB free disk space is available before configuring a node as an FMPM node.

  • Before you begin, ensure that you have the following information available:

    • IPv4 address and subnet mask for the eth0 Ethernet interface

    • (Optional) IPv6 address and prefix for the eth0 Ethernet interface

    • IPv4 address of the default gateway

    • (Optional) IPv6 address of the default gateway

    • IPv4 address of the name server

    • (Optional) IPv6 address of the name server

    • Virtual IP (VIP) address of the FMPM nodes in IPv4 and IPv6 formats

      The VIP address is used for communications between Junos Space nodes and FMPM nodes. This IP address must be in the same subnet as the IP address assigned to the eth0 Ethernet interface, and the VIP address must be different from the VIP address used to access the Web GUI.

    • IPv4 address or URL of NTP source to synchronize time

    • (Optional) IPv4 address of the eth1 Ethernet interface.

      If the IP address of the eth1 interface is not in the same subnet as the VIP address, ensure that you have the subnet mask and the default gateway for the eth1 interface.

    • (Optional) IPv4 address for the NAT trap

    • (Optional) IPv6 address for the NAT trap

    • (Optional) Port number for the NAT trap

Before you begin, ensure that you have the following information available:

This topic discusses the following tasks:

Configuring the Junos Space Virtual Appliance as the Primary FMPM Node

You can configure a Junos Space Virtual Appliance as an FMPM node.

To configure the virtual appliance as the first or primary FMPM node:

  1. Using a virtual machine client (such as VMware vSphere Client or Virtual Machine Manager [VMM]), log in and power on the Junos Space Virtual Appliance.
  2. Access the console on the virtual machine client to view the Junos Space login prompt.
  3. At the Junos Space login prompt, type admin as your default login name and press Enter.
  4. Type abc123 as your default password and press Enter.

    Junos Space prompts you to change your default password.

  5. Type the default password again and press Enter.
  6. Type the new password and press Enter.
    Note:

    You can choose a password that is at least eight characters long and contains characters from at least three of the following four character classes: uppercase letters, lowercase letters, numbers (0 through 9), and special characters.

    However, if a password satisfies the preceding criteria but contains only a single uppercase letter at the beginning or only a single number at the end, then that password is considered invalid. For example, Abcdwip9, Qc9rdiwt, and bRfjvin9 are invalid passwords, but AAbcdwip99, Qc9rdiwtQ, and bRfjvin99 are valid passwords.

    Alternatively, instead of using a string of characters, you can choose a passphrase that is between 16 and 40 characters long and contains at least three dictionary words separated by at least one special character. For example, big#three;fork (14 characters long) and circlefaceglass (no special characters) are invalid passphrases, but @big#three;fork& and circle;face;glass are valid passphrases.

    Passwords and passphrases are case-sensitive.

  7. Retype your new password.

    If the password is changed successfully, the message passwd: all authentication tokens updated successfully. is displayed.

  8. Type F to configure the virtual appliance as a standalone or primary FMPM node and press Enter when prompted Choose the type of node to be installed.
  9. Configure the IP address of the eth0 Ethernet interface.

    This IP address will be used as the IP address of the FMPM node.

    • To configure the IPv4 address of the eth0 interface:

      1. Type 1.

      2. Type the IPv4 address for the eth0 interface in dotted-decimal notation and press Enter.

        Note:

        All nodes that you configure in a cluster (fabric) must be in the same subnet.

      3. Type the new subnet mask for the IPv4 address and press Enter.

      4. Type the IP address of the default gateway for the eth0 Ethernet interface in dotted-decimal notation and press Enter.

    • To configure both IPv4 and IPv6 addresses:

      1. Type 2.

      2. Type the IPv4 address for the eth0 interface in dotted-decimal notation and press Enter.

      3. Type a subnet mask for the eth0 interface in dotted-decimal notation and press Enter.

      4. Type the IPv4 address of the default gateway for the eth0 interface in dotted-decimal notation and press Enter.

      5. Type the IPv6 address and prefix for the eth0 interface and press Enter.

      6. Type the IPv6 address of the default gateway for the eth0 interface and press Enter.

  10. Type the IPv4 address of the name server and press Enter.
  11. Type the IPv6 address of the name server and press Enter.
  12. Type P when prompted Choose the role for this FMPM specialized node [P/B].

    The FMPM node can be configured as follows:

    • (P)rimary - Standalone or first FMPM node in an FMPM high availability pair

    • (B)ackup - Backup FMPM node in an FMPM high availability pair

    Choosing P installs the node as a standalone FMPM node or the primary node in an FMPM HA setup. This node performs fault and performance monitoring of the devices and nodes, and any events or alarms is stored in a PostgreSQL database on this node.

  13. Configure the IP address for the FMPM service.

    This IP address is the VIP address of the FMPM nodes and is used for communication between the Junos Space nodes and the FMPM nodes.

    Note:

    The FMPM service IP address and the FMPM node IP address should be in the same subnet.

    Note:

    If you configure only an IPv4 address for the eth0 interface, you are provided with an option to configure only the IPv4 address for the FMPM service.

    1. Type 1 to configure the IPv4 and IPv6 addresses for the FMPM service.
    2. Type the IPv4 address for the FMPM service and press Enter.
    3. Type the IPv6 address for the FMPM service and press Enter.

    You are prompted to specify whether you want to configure NAT.

  14. Specify whether you want to configure access to Junos Space using NAT.

      If you enter C, you are prompted to retype all the basic configuration information that you have configured up to this point.

  17. Expand the VM drive size.

    Expand the /var partition by 120 GB.

    Note:

    Before expanding the VM drive size for an FMPM node, ensure that enough disk space is available on the host for allocation to the partitions. If no free space is available for allocation, the No free disk space message appears and the Junos Space Settings Menu is displayed.

    The minimum disk space required for the /var partition is 120 GB.

    1. Type 6 to expand the VM drive size.
    2. Enter the admin password.
      Note:

      No caution is displayed for node reboot while expanding the drive size for an FMPM node. However, the FMPM node is rebooted after the drive size is expanded.

    3. Type y to continue expanding the drive size or type n to return to the Junos Space Settings Menu.

      If you type y, you are prompted to specify the partition that you want to expand.

    4. Enter the number present against the partition that you want to expand; for example, type 2 to expand the /var partition or 5 to quit expanding disks and return to the Junos Space Settings Menu.

      The free space that can be allocated is displayed and you are prompted to enter the space that you want to allocate to the partition.

    5. Type the additional disk space that you want to allocate and press Enter.

      You can enter the disk space in megabytes (M), gigabytes (G), or terabytes (T). Do not add a space between the number and the unit; for example, 50M and not 50 M, 10G and not 10 G, and so on.

      You are prompted whether you want to expand more drives.

    6. Type y to continue adding disk space or N to return to the Junos Space Settings Menu.

      When you type N, the node is rebooted and the opennms process that was stopped is resumed. If the VM drive size was expanded on a primary node, the node becomes secondary when it comes up.

  18. Type Q to exit the Junos Space Settings Menu.

    The FMPM node is ready to be added to the space cluster. See Adding a Node to an Existing Junos Space Fabric for information about adding a node to the Junos Space cluster.
