SHOW OBSERVERS

The SHOW OBSERVERS command shows information about all observers for all broker configurations in a specific configuration group.

The SHOW OBSERVERS command displays the observer name, the host name where the observer is running, whether the observer is the master observer, and the last time the observer pinged the primary and standby.

Format

SHOW OBSERVERS [FOR <configuration_group_name> ];

Command Parameters

configuration_group_name
The name of a valid broker configuration group file for which you want to show information about all running observers. Specifying this parameter results in information being shown about observers for all configurations in the specified group. The information shown by this command is the same as that shown by a SHOW OBSERVER command on an individual configuration.

If a group name is not specified, then SHOW OBSERVERS alone is also a valid command. It shows observer information for all broker configuration groups defined in the observer configuration file.

The configuration group name cannot be ALL.

Usage Notes

  • This command can be used to verify that a manually performed switch to a new master observer was successful.
