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 should have the following values for each node type.

  Primary Node Backup Node Monitoring Node

Operating Mode

Messaging Node

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

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 (*).
