Chapter 4. Configuring Hammer


The default location for global hammer configuration is:

  • /etc/hammer/cli_config.yml for general hammer settings
  • /etc/hammer/cli.modules.d/ for CLI module configuration files

You can set user specific directives for hammer (in ~/.hammer/cli_config.yml) as well as for CLI modules (in respective .yml files under ~/.hammer/cli.modules.d/).

To see the order in which configuration files are loaded, as well as versions of loaded modules, use:

$ hammer -d --version

Note

Loading configuration for many CLI modules can slow down the execution of hammer commands. In such a case, consider disabling CLI modules that are not regularly used.

Apart from saving credentials as described in Chapter 3, Hammer authentication, you can set several other options in the ~/.hammer/ configuration directory. For example, you can change the default log level and set log rotation with the following directives in ~/.hammer/cli_config.yml. These directives affect only the current user and are not applied globally.

:log_level: 'warning'
:log_size: 5 #in MB

Similarly, you can configure user interface settings. For example, set the number of entries displayed per request in the Hammer output by changing the following line:

:per_page: 30

This setting is an equivalent of the --per-page Hammer option.

Many hammer commands are organization specific. You can set a default organization and location for hammer commands so that you do not have to specify them every time with the --organization and --location options.

Specifying a default organization is useful when you mostly manage a single organization, as it makes your commands shorter. However, when you switch to a different organization, you must use hammer with the --organization option to specify it.

Procedure

  1. Set a default organization:

    # hammer defaults add --param-name organization \
    --param-value "Your_Organization"
    Copy to Clipboard Toggle word wrap

    You can find the name of your organization with the hammer organization list command.

  2. Optional: Set a default location:

    # hammer defaults add --param-name location \
    --param-value "Your_Location"
    Copy to Clipboard Toggle word wrap

    You can find the name of your location with the hammer location list command.

Verification

  1. Review the currently specified default settings:

    # hammer defaults list
    Copy to Clipboard Toggle word wrap

4.2. Increasing the logging level for Hammer

You can find the log in ~/.hammer/log/hammer.log.

Procedure

  • In /etc/hammer/cli_config.yml, set the :log_level: option to debug:
:log_level: 'debug'
