    Spoke actions

    The Gremlin spoke provides actions to automate Gremlin tasks when events occurs in your ServiceNow instance. Available actions include:

    Category Action Description
    Attack Management Create Attack Creates an attack on the Gremlin platform.
    Get Attack Details Retrieves details about an attack.
    Get Attack Executions Retrieves a list of executions associated with an attack.
    Halt All Attacks Idempotently halts all active attacks across the Gremlin platform.
    Look up Attacks Lists all attacks on the Gremlin platform.
    Note:
    • By default, this action can retrieve data up to 5 MB. You can configure the glide.pf.rest.response_payload_max_size property to retrieve data up to 10 MB. If the data in the response is more 10 MB, an error is displayed.
    • As data up to 10 MB only can be retrieved, you can also specify number of records that should be retrieved in the input field, Number of records to return.
    Attack Schedule Management Create Attack Schedule Creates an attack schedule on the Gremlin platform.
    Delete Attack Schedule Deletes the specified attach schedule.
    Get Attack Schedule Details Retrieves details about the specified attack schedule.
    Look up Active Attack Schedules Lists all the attack schedules on the Gremlin platform.
    Note:
    • Time zone that is considered in the spoke actions, is same as the time zone of your ServiceNow instance.
    • Based on your Gremlin license, if you don't have access to certain Gremlin functionality, you can't use the associated spoke actions in your ServiceNow instance as well.
    • For some arguments that take True or False as input, the actual value that the Gremlin platform considers, might be different from the value you have provided.

    Connection and credential alias requirements

    Integration Hub uses aliases to manage connection and credential information, and OAuth credentials. Using an alias eliminates the need to configure multiple credentials and connection information profiles when using multiple environments. If the connection or credential information changes, you don't need to update any actions that use the connection.

    For information about setting up the spoke, see Create Connection and Credential record for the Gremlin spoke.
