You can configure a Junos Space 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. The second FMPM node that you configure is the backup or secondary
FMPM node. The PostgreSQL database containing the fault and performance monitoring
data is replicated from the primary FMPM node to the secondary FMPM node. When the
primary node is down or being rebooted, the secondary node automatically assumes
charge.
A primary and a secondary FMPM node are referred to as a cluster or a team; therefore,
an FMPM team can consist of a maximum of two nodes.
NOTE: You must have at least one appliance already configured as a Junos
Space node, and an appliance configured as a primary FMPM node, before
you configure a different appliance as a secondary FMPM node.
To configure a Junos Space Appliance as a backup or secondary FMPM node, you must
configure basic network and system settings to make the appliance 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.
Before you begin, do the following:
Ensure that the Junos Space Appliance is connected to a management console and
that the management device is powered on.
Ensure that the appliance is booted and displays the login prompt at the console.
Ensure that 100 GB free disk space is available before configuring a node as an FMPM
node.
Ensure that you have the following information available:
