Description

Options and arguments

--configname config-name

Specifies the name of the application configuration.

--devicetype device-type

Specifies the device type that is associated with the command.

-d,--domain-id did

Specifies the domain identifier.

If you do not specify this option, IBM® Streams uses the domain name that is set in the STREAMS_DOMAIN_ID environment variable. By default, that domain name is StreamsDomain. If you are using the interactive streamtool interface, it uses the name of the active domain for the current streamtool session or else it prompts you for the domain name.

The active domain for the current streamtool session is set every time that you successfully run a streamtool command with a -d or --domain-id option. Alternatively, you can run the streamtool domain command in the interactive interface.

--embeddedzk

Specifies to use the embedded copy of ZooKeeper. This option is not supported within the interactive streamtool interface.

If you are not using the interactive streamtool interface and you do not specify either this option or the --zkconnect option, IBM Streams uses the ZooKeeper connection that is associated with the active domain or the domain that is specified in the --domain-id option. IBM Streams determines which connection maps to the domain by using cached information about the domains. In this scenario, if the domain identifier is not unique in the IBM Streams configuration cache, the command fails.

--fmt format-spec

Specifies the presentation format. The command supports the following values:

• %Mf: Multiline record format. One line per field.
• %Nf: Name prefixed field table format. One line per processing element.
• %Tf: Standard table format, which is the default. One line per host check result.

-h,--help

Specifies to show the command syntax.

-i, --instance-id iid

Specifies the instance identifier.

If you do not specify this option, IBM Streams uses the instance identifier that is set in the STREAMS_INSTANCE_ID environment variable. By default, that instance identifier is StreamsInstance. If you are using the interactive streamtool interface, it tries to use an instance ID that you specified in a previous command. If no such value is found, the command uses the STREAMS_INSTANCE_ID environment variable. Alternatively, you can run the streamtool instance command in the interactive interface.

--outfile file-name

Specifies the name of the output file in which the command writes the list of device information.

--trace level

Specifies the trace setting. The following valid levels are listed in order of increasing verbosity, which is to say that the first level in the list generates the least amount of information:

• off
• error
• warn
• info
• debug
• trace

The default value is off.

-U,--User user

Specifies an IBM Streams user ID that has authority to run the command.

-v,--verbose level

Specifies to provide more detailed command output. You must specify one of the following verbosity levels:

• 0: This level disables detailed reporting.
• 1: This level provides detailed information only for resources that have problems and for situations where checks fail.
• 2: This level provides detailed information for each resource that is checked.
• 3: This level provides detailed information for everything that the command checks.

--zkconnect host:port

The name of one or more host and port pairs that specify the configured ZooKeeper servers. This option is not supported within the interactive streamtool interface.

If you are not using the interactive streamtool interface and you do not specify this option, IBM Streams tries to use:

1. The --embeddedzk option
2. The value from the STREAMS_ZKCONNECT environment variable
3. A ZooKeeper connection string that is derived from cached information about the current domain.
