Working with Nodes

A FortiSIEM node is part of an Analytics cluster and can be of four types:

  • Supervisor node: this can be of 3 sub-types

    • Primary Leader - this node is instantiated when the system is installed

    • Primary Follower (can be instantiated if High Availability is enabled)

    • Secondary Supervisor (can be instantiated if Disaster Recovery is enabled)

  • Worker node

 

The following features are available from the License > Nodes page.

Viewing a Node

The Nodes tab displays information on your existing nodes. You can refresh this page by clicking on the refresh icon. If you are working with nodes for ClickHouse, see the ClickHouse Configuration page for specific ClickHouse information on handling nodes.View, add, edit, or delete nodes from this page.

The Nodes table allows you to view the following information.

Settings Description
Host Name The host name of the node.
IP Address The IP address of the node.
Mode

Displays what the node is working as - Worker or Supervisor.
HA/ DR Role High Availability (HA) Role shows what role a node is acting as in a Supervisor Cluster. A node will either be Primary Leader, or a Primary Follower in an Supervisor Cluster configuration.

Disaster Recovery (DR) Role shows what role a node is acting as in Disaster Recovery, either Primary or Secondary.
HA/DR Status Displays the status of the node. For Disaster Recovery, Active indicates that the Primary and Secondary nodes are in sync and that Disaster Recovery is working. If the status is Inactive in either the Primary or Secondary nodes involved with Disaster Recovery, it means that the Primary and Secondary are NOT in sync, and that Disaster Recovery is not working. For a Supervisor node not in Disaster Recovery or a Worker node, the Replication Status appears as N/A.
Leader Displays who the leader node is for the follower node in a High Availability Supervisor Cluster configuration.
Licensed Displays the current license status of the node.
