Configure the ServiceNow Discovery connector

The Snow Integration Connector for ServiceNow Discovery is configured in the Snow Integration Manager (SIM). For more information on SIM, see Snow Integration Manager.

The ServiceNow Discovery connector uses an API connection.

Prerequisites

A user account with read-only access to the ServiceNow CMDB tables is required to configure the connector.

Set up the Data connection

In Snow Integration Manager, add the ServiceNow Discovery connector, select the Data connection tab, and configure the settings:

1. In the Endpoint URL box, enter the URL to the ServiceNow instance.

   EXAMPLE

   https://myCompany.service-now.com

2. If a port other than the default port of 80 is configured in ServiceNow, in the Port, enter a port number.

3. In Time out, select the time frame, in seconds, before the connection to ServiceNow will time out. The default value is 30 seconds.

   A value other than the default value should be entered if the connection to ServiceNow times out before all data is collected. To determine a reasonable timeout period:

   In ServiceNow, navigate to System Logs, open the Transactions page, and adjust the timeout period based on the API call response times displayed in column Response time.

4. In the User name and Password, enter the credentials for a user account with access to the ServiceNow API.

5. To verify the connection, select Test connection.

6. In the Initial aggregation length (months), select the number of months that the initial aggregation of inventory data will be based upon.

7. To reset an ongoing incremental aggregation, select Clear Last Aggregation Date.

8. Optional: Enter a Site name for this connector, which will override the global site name.

9. To save the configured settings and close the window, select OK.
