Add a ServiceNow Account

You can add ServiceNow as a data source in vRealize Network Insight and fetch your application and tier details. The ServiceNow Configuration Management Database (CMDB) provides you with full visibility of software and hardware infrastructure and the relation between them in your data center. This visibility helps you in managing your inventory.

With ServiceNow integration, vRealize Network Insight can discover applications available in ServiceNow CMDB to enable you to directly add them into vRealize Network Insight.
