Authority

Description

Options and arguments

--connectivity-only

Specifies to run only the connectivity checks.

-d,--domain-id did

Specifies the domain identifier.

If you do not specify this option, InfoSphere 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, InfoSphere Streams uses the ZooKeeper connection that is associated with the active domain or the domain that is specified in the --domain-id option. InfoSphere 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 InfoSphere 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.

--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 InfoSphere Streams user ID that has authority to run the command.

-v,--verbose level

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

• 0: This level disables detailed reporting.
• 1: This level provides a summary for each resource that is checked.
• 2: This level provides detailed information for each resource that is checked.

--xclient

Specifies to use the first resource in the list of resources that is allocated to the domain (in alphabetical order) as the reference for operating system and architecture checks. If you do not specify this option, the resource where you run the command is used for the comparison checks unless that resource is not allocated to the domain.

--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, InfoSphere 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.
