## Summary of Gremlin Spoke
The Gremlin Spoke enables ServiceNow customers to simulate outages and manage attacks directly from their ServiceNow instance by integrating with a Gremlin instance.
This integration automates Gremlin tasks and attack management through predefined actions triggered by ServiceNow events.
However, starting with the Yokohama release, the Gremlin Spoke is being prepared for deprecation and will no longer be activated on new instances, though support will continue for existing users.
Customers are encouraged to explore the Spoke Generator for the latest experience.

## Key Features
* **Attack Management Actions:** Create, retrieve details, list executions, halt all active attacks, and look up attacks on the Gremlin platform.
* **Attack Schedule Management:** Create, delete, retrieve details, and list attack schedules with time zone alignment to the ServiceNow instance.
* **Data Handling:** Supports response payloads up to 10 MB configurable via system properties, with options to limit record count to manage large datasets.
* **Connection Management:** Uses Integration Hub aliases for managing credentials and connections efficiently across multiple environments without updating individual actions.
## Requirements and Dependencies
* Integration Hub subscription is required to use the Gremlin Spoke.
* Admin access to the Gremlin dashboard and a configured Gremlin team with Team ID and API Key for authentication.
* Dependent ServiceNow plugins must be installed, including IntegrationHub Runtime, Complex Object, Flow Designer - Dynamic Inputs, and IntegrationHub Action Step - REST, which may require appropriate licenses.
* Compatible primarily with Gremlin version v1, with possible compatibility for later versions.
## Practical Considerations
* Permissions and license limitations on the Gremlin platform will restrict access to some spoke actions accordingly.
* Some boolean input parameters may be interpreted differently by Gremlin, requiring careful input validation.
* Time zone handling for schedule-related actions follows the ServiceNow instance's time zone settings.
## Next Steps for Customers
* Ensure you have the necessary Integration Hub subscription and dependent plugins installed and licensed.
* Set up your Gremlin team and retrieve necessary credentials (Team ID and API Key) for integration.
* Configure connection and credential aliases in Integration Hub to streamline multi-environment management.
* Plan for transition away from the Gremlin Spoke in future releases by exploring the Spoke Generator alternative.
Simulate outages and manage attacks using Gremlin instance from your ServiceNow instance.
Important:
Starting with the Yokohama release, Gremlin Spoke is being prepared for future deprecation. It will be hidden and no longer activated on new instances but will continue to be supported. Spoke Generator provides the latest
experience for this functionality.
For details, see the [Deprecation Process \[KB0867184\]](https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB0867184) article in the Now Support knowledge base.

## Supported versions {#gremlin-spoke__section_zjt_sh4_zgb}
This spoke was built for Gremlin version v1, but may be compatible with later versions.
## Spoke requirements {#gremlin-spoke__section_cqn_msx_qlb}
* Set up clients as per your requirement.
* Admin access to the Gremlin dashboard.
* Team in your Gremlin account for integration with ServiceNow instance. For more information about creating teams, see [Teams](https://www.gremlin.com/docs/users-and-teams/teams/).
* Team ID and API Key of the team. Copy and record these value for later use. For more information about accessing these values, see the [Signature-based Authentication](https://www.gremlin.com/docs/infrastructure-layer/authentication/) section.

## Spoke dependencies {#gremlin-spoke__section_tmn_vsx_qlb}
If you're having trouble installing the app, ensure that these dependent plugins are installed:
* ServiceNow IntegrationHub Runtime (com.glide.hub.integration.runtime)
* Complex Object (com.glide.cobject)
* ServiceNow Flow Designer - Dynamic Inputs (com.glide.hub.dynamic_inputs)
* ServiceNow IntegrationHub Action Step - REST (com.glide.hub.action_step.rest)
{#gremlin-spoke__ul_p1h_xsx_qlb}
Note:
Some of these plugins are licensable features and require appropriate licenses, if used outside the spoke implementation.
## Spoke actions {#gremlin-spoke__section_b43_3h2_hfb}
The Gremlin spoke provides actions to automate Gremlin tasks when events occurs in your ServiceNow instance. Available actions include:
{#gremlin-spoke__table_u1p_kh2_hfb__entry__3}
| Category | Action | Description |
|-|-|-|
| Attack Management | Create Attack | Creates an attack on the Gremlin platform. |
| Attack Management | Get Attack Details | Retrieves details about an attack. |
| Attack Management | Get Attack Executions | Retrieves a list of executions associated with an attack. |
| Attack Management | Halt All Attacks | Idempotently halts all active attacks across the Gremlin platform. |
| Attack Management | 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. {#gremlin-spoke__ul_ymz_ny3_ppb} |
| Attack Schedule Management | Create Attack Schedule | Creates an attack schedule on the Gremlin platform. |
| Attack Schedule Management | Delete Attack Schedule | Deletes the specified attach schedule. |
| Attack Schedule Management | Get Attack Schedule Details | Retrieves details about the specified attack schedule. |
| Attack Schedule Management | Look up Active Attack Schedules | Lists all the attack schedules on the Gremlin platform. |

{#gremlin-spoke__table_u1p_kh2_hfb}
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.
{#gremlin-spoke__ul_n2y_jbj_3mb}
## Connection and credential alias requirements {#gremlin-spoke__section_ibn_pj2_hfb}
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](https://www.servicenow.com/docs/uUnf~XwOqADywTCtrJF2Nw "Authorize the Gremlin spoke actions by creating connection and credential record for the application registered in Gremlin. The Gremlin spoke connection and credential alias uses these connections and credentials to authorize actions.").
