Using the Command Console


The Fuse ESB Enterprise command console is the central tool for both managing the Fuse ESB Enterprise environment and interacting with Fuse Fabric. When you start Fuse ESB Enterprise the console starts automatically.

The console provides commands that you can use to perform basic management of your Fuse ESB Enterprise environment, including deploying and configuring applications.

The console uses prefixes to group commands relating to the same functionality. For example, commands related to configuration are prefixed config:, and logging-related commands are prefixed log:.

Starting the command console

To start Fuse ESB Enterprise, open a command prompt in the installation directory and enter:


Fuse ESB Enterprise starts and the console is ready. You should see the prompt shown in Example 1.

Example 1. The Fuse ESB Enterprise Console

______                   _____  _____ ______ 
|  ___|                 |  ___|/  ___|| ___ \
| |_  _   _  ___   ___  | |__  \ `--. | |_/ /

  Fuse ESB (7.0.0.fuse-beta-042)

Hit '<tab>' for a list of available commands
and '[cmd] --help' for help on a specific command.
Hit '<ctrl-d>' or 'osgi:shutdown' to shutdown Fuse ESB.


Getting help

The console provides two levels of help:

  • console help—list all of the commands along with a brief summary of the commands function

  • command help—a detailed description of a command and its arguments

To access the console help, enter the help command from the console prompt. It displays a grouped list of all the commands available in the console. Each command in the list is followed by a description, as shown in Example 2.

Example 2. Console Help

FuseESB:karaf@root> help
                Creates a broker instance.
                Destory a broker instance.
                Changes the Java options of an existing container instance.
                Changes the RMI registry port (used by management layer) of an 
                existing container instance.

The help for each command includes the definition, the syntax, and the arguments and any options. To display the help for a command, type the command with the --help option. As shown in Example 3, entering admin:start --help displays the help for that command.

Example 3. Help for a Command

FuseESB:karaf@root> admin:start --help

        Starts an existing container instance.

        admin:start [options] name

        name           The name of the container instance

                       Display this help message
        -o, --java-opts
                       Java options when launching the instance


Command completion

Pressing Tab at anytime provides you with a list of commands that can complete what you have already entered at the prompt. For example, if you enter active followed by Tab, a list similar to Example 4 is shown.

Example 4. Console Commands

activemq:bstat                    activemq:create-broker
activemq:destroy-broker           activemq:list
activemq:purge                    activemq:query

If you press Tab without entering anything at the prompt, the console lists all of the available commands.

Command groups

Commands are grouped under prefixes according to functionality. Table 1 summarizes the command groups available in the console. Click on a command group name for more information.

Table 1. Apache ActiveMQ Command Groups

web Lists the WARs deployed in the container.
zk Accesses and modifies entries in the Zookeeper registry.

Short version

Many of the console commands allow you to omit the group prefix.

If the command is only in one command groups, you can omit the group prefix. For example, you can enter bstat in place of activemq:bstat because it only exists in the activemq command group.

If the command exists in multiple command groups, you can still drop the prefix and the console will default to using the version of the command from one of the following command groups:

  • shell

  • osgi

  • admin

For example, info is equivalent to shell:info. If you wanted to use osgi:info, you need to enter the full command.
