ServiceNow CMDB#

Connect ServiceNow to import the CIs already recorded in your CMDB, and to keep each Guardian CI linked to the CMDB CI it represents. The same connection is used by change reconciliation.

Connect and import#

  1. Choose Bulk import from ServiceNow when adding CIs, or manage the connection from Settings › Integrations.
  2. Enter your ServiceNow instance URL and credentials: a username and password, or an OAuth client ID and secret.
  3. Choose the CMDB CI classes Guardian will import, such as cmdb_ci_server. You can import all CIs in a class or select some.
  4. Start the sync. Guardian pulls the CI records from your CMDB; a large CMDB can take a while.

Guardian keeps one ServiceNow connection per organisation.

To link a Guardian CI to a CMDB CI yourself, open the CI and select Link CMDB CI. Search your CMDB by name or IP address and pick the match. Unlink CMDB CI removes it.

Manage sync jobs#

Settings › Integrations › ServiceNow shows your sync jobs. Retry failed runs from there. If a sync is already running when you start one, Guardian tells you rather than starting a second.

Good to know

To change the saved credentials, delete the integration and connect again.
