Cluster: Configure Atlas Technology for Load Balancing

Note: This feature is available only to customers who own an on-premises Bomgar Appliance. Bomgar Cloud customers do not have access to this feature.

Management > Cluster

Cluster :: Status

Large-scale geographic deployments benefit from Bomgar Atlas Cluster technology, establishing a single Bomgar site across multiple appliances, which are termed nodes in a cluster. The master appliance/primary master node is the site of most administration tasks. The traffic node is a Bomgar Appliance that participates in effectively routing your support traffic.

On the primary master node, you will configure both the primary master itself and the traffic nodes.

Find more information about Atlas in the Bomgar Atlas Technology Guide, available at www.bomgar.com/docs.

Current Status

Confirms the role of the site instance from which you accessed the page.

Sync Now

Synchronize the clustered appliances.

Disband Cluster

Disband the cluster, effectively removing each appliance from its role in the cluster.

Status History

Show or hide the log of clustered appliance messages.

Cluster :: Master Node Configuration

Name

Create a unique name to help identify this object.

Public Address

Enter the hostname you set up in DNS for this node, and enter the port over which clients will communicate with the node.

Internal Address

This can be the same as the public address. Advanced configurations can optionally set this to a different hostname for inter-appliance communication.

Maximum Client Fallback to Master

Allows the number of clients you set to fall back to using the master for traffic control if necessary.

Cluster :: Traffic Nodes

Method for Choosing Traffic Nodes

This selector is used to define how a traffic node is chosen for a representative or customer client connection. The available methods for defining the connection are Random, A Record Lookup, SRV Record Lookup, IP Anycast, and Timezone Offset. Your choice of connection method is highly dependent upon your network infrastructure, among other complex considerations.

Add New Traffic Node, Edit Node, Remove Node

Create a new object, modify an existing object, or remove an existing object.

Accepting New Client Connections

Be sure this is checked; otherwise, clients will not be able to use the traffic node.

Cluster :: Add Traffic Node

Name

Create a unique name to help identify this object.

Public Address

Enter the hostname you set up in DNS for this node, and enter the port over which clients will communicate with the node.

Internal Address

This can be the same as the public address. Advanced configurations can optionally set this to a different hostname for inter-appliance communication.

Accepting New Client Connections

Be sure this is checked; otherwise, clients will not be able to use the traffic node.

Network Address Prefixes

You may leave this blank.

For advanced configurations, enter network address prefixes, one per line, in the form of ip.add.re.ss[/netmask]. Netmask is optional and can be given in either dotted-decimal format or as an integer bitmask. If netmask is omitted, as single IP address is assumed.

When this field is populated, the master node attempts to assign a client to this traffic node if the client's IP address matches one of the network address prefixes. If the client's IP address matches more than one traffic node's network address prefixes, the client is assigned to the traffic node with the longest matching prefix. If the matching prefixes are of equal length, one of the matching traffic nodes is chosen at random. If a client's IP address does not match any network address prefixes, the client is assigned using the method configured.

Timezone Offset

Used only if Method for Choosing Traffic Nodes is set to Timezone Offset. This process involves detecting the time zone setting of the host machine and using that setting to match the appropriate traffic node that has the closest time zone offset. The time zone offset is derived from the customer time zone setting relative to Coordinated Universal Time (UTC).
