Some ITSM solutions offer out-of-the-box plugins to integrate with vRealize Operations.
For example, ServiceNow offers integration to vRealize Operations through its Event Management plugin.
For this integration to work, you have to configure a Management, Instrumentation, and Discovery (MID) server in ServiceNow and connect it to a vRealize Operations instance to obtain event information. Events are collected from vRealize Operations using a pull operation. Events will start to be received from the vRealize Operations server according to the pull interval schedule.
Refer to the ServiceNow IT Operations Management documentation online for more info.
