Rule 5 - Correlation ID and Correlation Prefix Value for VMware SD-WAN

Rule Synopsis

These are the rule/s that control whether a user defined value is prepended to the default Correlation ID value on each CMDB CI record.

Rule Details and Default

  • CI Sync’s default format of the Correlation ID value of SD-WAN CIs is the “_href” attribute value within VMware SD-WAN.

  • By default, CI Sync does not prepend any user defined prefix value to the Correlation ID value.

Override Options

Context

Customers may consider overriding the default rule to set a different Correlation ID prefix value to meet their specific ServiceNow requirements.

The use of the Correlation ID prefix value can be important when multiple separate VMware SD-WAN environments (e.g. accounts or other similar delineations within an organisation) are being synced to a single destination ServiceNow CMDB.  Customers may want to use a unique Correlation ID prefix for each individual VMware SD-WAN environment.

Options

  1. The rule can be amended so that CI Sync does prepend a user defined static value as the prefix to the Correlation ID.

Overriding via Connection Settings

Customers can perform the override using a “Connection Setting” via the CI Sync User Interface (i.e. customers can perform the overrides themselves). Additional information for this is available via the following documentation:

  1. For a general overview of CI Sync Connection Settings please read Understanding the use of CI Sync Connection Settings.

  2. For the specific CI Sync Connection Setting/s related to the rule described on this page please read Correlation Fields for VMware SD-WAN.

For documentation on all CI Sync Connection Settings please visit the page tree Connection Setting Guides.

Additional Information

  • A separate/individual prefix value can be used on each CI Sync source system connection therefore creating uniqueness of the Correlation ID across multiple VMware SD-WAN instances.
