Monitoring Redundancy

This section discusses the show commands that you can use to view the configuration and state of Solace PubSub+ software event brokers used in high-availability (HA) deployments.

Showing Redundancy Information

To view the redundancy configuration and status for an event broker, enter the following show command:

solace> show redundancy [detail | group [node <name-pattern> [detail]]]

Where:

detail specifies to show detailed information on the redundancy configuration.

group [node <name-pattern> [detail]] specifies to show information for a specific HA node (for example, you can show details for just the monitoring node, solace3 in the example below).

To read descriptions of many of the show commandsʾ output values, enter a "?" at the end of the command (for example solace 1> show redundancy ?).

Checking for Proper Configurations

For a properly operating HA group, the Operating Mode and Active/Standby Role parameters must have the following values for each node type.

	Primary Node	Backup Node	Monitoring Node
Operating Mode	Messaging Node	Messaging Node	Monitoring Node
Active-Standby Role	Primary	Backup	Undefined

For a properly operating HA group, the proper Activity Status for each node will be as follows:

	Primary Node	Backup Node	Monitoring Node
Activity Status	Primary Virtual Router: Local Active Backup Virtual Router: Shutdown	Primary Virtual Router: Shutdown Backup Virtual Router: Mate Active	Primary Virtual Router: Shutdown Backup Virtual Router: Shutdown

Showing Redundancy Groups

To view information regarding the HA group and its constituent nodes, enter the following show command:

solace1> show redundancy [group [node <name-pattern> [detail]]]

The current node is highlighted with a star symbol (*).
