Authority
To get log or trace data for a domain, you must have read authority for the system-log domain object.
To get log or trace data for an instance, you must also have read authority for the system-log domain object and the system-log instance object.
To get log or trace data for jobs, you must also have read authority for the system-log domain object, the system-log instance object, and the application-log instance object.
By default, the DomainAdministrator role has this authority.
For more information, see streamtool getacl and streamtool getdomainacl.
Description
By default, the streamtool getlog command saves log and trace data in the StreamsLogs.tgz file. To specify a different file name, use the --file option.
- Log data: For log data only, use the --log option.
- Trace data: To include application trace data, use the --includeapps option.
When data collection is performed by a user who is not the instance owner, InfoSphere Streams does not collect the instance security configuration data in the security-config.xml file. If this situation occurs, a warning message is displayed which states that the user does not have the correct permission to access the security configuration. InfoSphere Streams collects all other log and trace data.
To view log and trace files in your specified editor, use the streamtool viewlog command.
Options and arguments
- --collection-directory collection-directory
Specifies the directory that is used for storing temporary copies of intermediate log collection results. If you do not specify this command option, the domain log path is used for temporary storage.
- -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.
- -f, --file file-name
Specifies the file path that the command uses to store the compressed tar file output. By default, the following file is created in the current working directory: StreamsLogs.tgz.
- -h, --help
Specifies to show the command syntax.
- -i, --instance-id iid
Specifies the instance identifier.
If you do not specify this option, InfoSphere 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.
- --includeapps
Specifies to include the application trace data in the log file.
- --log
Specifies to collect only the domain log file. The domain log file contains the log data for the applications that are running in the domain. It also contains log data for the domain and instance services.
- --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
- -U, --User userid
Specifies an InfoSphere Streams user ID that has authority to run the command.
- -v,--verbose level
Specifies to provide more detailed command output. The vebosity level can be from 0 to 3 where each increment provides more detailed output.
- --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:- The --embeddedzk option
- The value from the STREAMS_ZKCONNECT environment variable
- A ZooKeeper connection string that is derived from cached information about the current domain.
