Create a ServiceNow connector

edit
Use the UI
edit

To create a new ServiceNow connector:

  1. Navigate to the Search → Connectors page in the Kibana UI.
  2. Follow the instructions to create a new native ServiceNow connector.

For additional operations, see Using connectors.

Use the API
edit

You can use the Elasticsearch Create connector API to create a new native ServiceNow connector.

For example:

PUT _connector/<my-servicenow-connector>
{
  "index_name": "<my-elasticsearch-index>",
  "name": "Content synced from ServiceNow",
  "service_type": "servicenow",
  "is_native": "true"
}
You’ll also need to create an API key for the connector to use.

The user needs the cluster privileges manage_api_key, manage_connector and write_connector_secrets to generate API keys programmatically.

To create an API key for the connector:

  1. Run the following command, replacing values where indicated. Note the id and encoded return values from the response:

    POST /_security/api_key
    {
      "name": "<connector_name>-connector-api-key",
      "role_descriptors": {
        "<connector_name>-connector-role": {
          "cluster": [
            "monitor",
            "manage_connector"
          ],
          "indices": [
            {
              "names": [
                "<index_name>",
                ".search-acl-filter-<index_name>",
                ".elastic-connectors*"
              ],
              "privileges": [
                "all"
              ],
              "allow_restricted_indices": false
            }
          ]
        }
      }
    }
  2. Use the encoded value to store a connector secret, and note the id return value from this response:

    POST _connector/_secret
    {
      "value": <encoded_api_key>
    }
  3. Use the API key id and the connector secret id to update the connector:

    PUT /_connector/<connector_id>/_api_key_id
    {
      "api_key_id": "<API key id>",
      "api_key_secret_id": "<secret id>"
    }

Refer to the Elasticsearch API documentation for details of all available Connector APIs.

Usage

Compatibility

edit

The ServiceNow connector is compatible with the following versions of ServiceNow:

  • ServiceNow "Tokyo"
  • ServiceNow "San Diego"
  • ServiceNow "Rome"
  • ServiceNow "Utah"
  • ServiceNow "Vancouver"

Configuration

edit

The following configuration fields are required to set up the connector:

ServiceNow URL
The host URL of the ServiceNow instance.
Username
The username of the account used for ServiceNow.
Password
The password of the account used for ServiceNow.
Comma-separated list of services

Comma-separated list of services to fetch data from ServiceNow. If the value is *, the connector will fetch data from the list of basic services provided by ServiceNow:

  • User
  • Incident
  • Requested Item
  • Knowledge
  • Change Request

    If you have configured a custom service, the * value will not fetch data from the basic services above by default. In this case you’ll need to mention these service names explicitly.

    Default value is *. Examples:

  • User, Incident, Requested Item, Knowledge, Change Request
  • *
Enable document level security
Restrict access to documents based on a user’s permissions. Refer to Document level security for more details.

Documents and syncs

edit

All services and records the user has access to will be indexed according to the configurations provided. The connector syncs the following ServiceNow object types:

  • Records
  • Attachments
Sync types
edit

Full syncs are supported by default for all connectors.

This connector also supports incremental syncs.

Document level security

edit

Document level security (DLS) ensures identities and permissions set in ServiceNow are maintained in Elasticsearch. This enables you to restrict and personalize read-access users and groups have to documents in this index. Access control syncs ensure this metadata is kept up to date in your Elasticsearch documents.

The ServiceNow connector supports roles for access control lists (ACLs) to enable document level security in Elasticsearch. For default services, connectors use the following roles to find users who have access to documents.

Service Roles

User

admin

Incident

admin, sn_incident_read, ml_report_user, ml_admin, itil

Requested Item

admin, sn_request_read, asset, atf_test_designer, atf_test_admin

Knowledge

admin, knowledge, knowledge_manager, knowledge_admin

Change Request

admin, sn_change_read, itil

For services other than these defaults, the connector iterates over access controls with read operations and finds the respective roles for those services.

The ServiceNow connector does not support scripted and conditional permissions.

Sync rules

edit

Basic sync rules are identical for all connectors and are available by default.

Advanced sync rules
edit

A full sync is required for advanced sync rules to take effect.

Advanced sync rules are defined through a source-specific DSL JSON snippet.

The following sections provide examples of advanced sync rules for this connector.

Indexing document based on incident number for Incident service
edit
[
  {
    "service": "Incident",
    "query": "numberSTARTSWITHINC001"
  }

Deployment using Docker

edit

You can deploy the ServiceNow connector as a self-managed connector client using Docker. Follow these instructions.

Step 1: Download sample configuration file

Download the sample configuration file. You can either download it manually or run the following command:

curl https://raw.githubusercontent.com/elastic/connectors/main/config.yml.example --output ~/connectors-config/config.yml

Remember to update the --output argument value if your directory name is different, or you want to use a different config file name.

Step 2: Update the configuration file for your self-managed connector

Update the configuration file with the following settings to match your environment:

  • elasticsearch.host
  • elasticsearch.api_key
  • connectors

If you’re running the connector service against a Dockerized version of Elasticsearch and Kibana, your config file will look like this:

# When connecting to your cloud deployment you should edit the host value
elasticsearch.host: http://host.docker.internal:9200
elasticsearch.api_key: <ELASTICSEARCH_API_KEY>

connectors:
  -
    connector_id: <CONNECTOR_ID_FROM_KIBANA>
    service_type: servicenow
    api_key: <CONNECTOR_API_KEY_FROM_KIBANA> # Optional. If not provided, the connector will use the elasticsearch.api_key instead

Using the elasticsearch.api_key is the recommended authentication method. However, you can also use elasticsearch.username and elasticsearch.password to authenticate with your Elasticsearch instance.

Note: You can change other default configurations by simply uncommenting specific settings in the configuration file and modifying their values.

Step 3: Run the Docker image

Run the Docker image with the Connector Service using the following command:

docker run \
-v ~/connectors-config:/config \
--network "elastic" \
--tty \
--rm \
docker.elastic.co/enterprise-search/elastic-connectors:8.15.2.0 \
/app/bin/elastic-ingest \
-c /config/config.yml

Refer to DOCKER.md in the elastic/connectors repo for more details.

Find all available Docker images in the official registry.

We also have a quickstart self-managed option using Docker Compose, so you can spin up all required services at once: Elasticsearch, Kibana, and the connectors service. Refer to this README in the elastic/connectors repo for more information.

edit
[
  {
    "service": "Knowledge",
    "query": "author.nameSTARTSWITHSystem Administrator"
  }
]

End-to-end Testing

edit

The connector framework enables operators to run functional tests against a real data source. Refer to Connector testing for more details.

To perform E2E testing for the ServiceNow connector, run the following command:

$ make ftest NAME=servicenow

Generate performance reports using the following flag: PERF8=yes. Toggle test data set size between SMALL, MEDIUM and LARGE with the argument DATA_SIZE=. By default, it is set to MEDIUM.

Users do not need to have a running Elasticsearch instance or a ServiceNow source to run this test. Docker Compose manages the complete setup of the development environment.
