START OBSERVING

The START OBSERVING command starts a new observer for each broker configuration in the specified group.

The effect of the START OBSERVING command is equivalent to submitting a START OBSERVER command on each individual configuration.

Format

START OBSERVING [<configuration_group_name>];

Command Parameters

configuration_group_name
The name of a broker configuration group, in which you want to start one observer for each broker configuration.

Usage Notes

  • If no configuration_group_name is specified, then this command will start a new observer for each configuration defined in the observer configuration file.

  • The configuration_group_name cannot be the keyword ALL.

  • Information about the DGMGRL commands run and execution details are written to the log file, superobserver.log. This file is located in the $DG_ADMIN/admin/ directory. If the DG_ADMIN environment variable is not defined, this file is located in the current working directory.
