Configure a single queue for Cloud-based and IP-based events

Configure Cloud-based and IP-based events to share a single queue, which helps reduce the impact of Discovery on app nodes.

Before you begin

Confirm the following:

• Discovery Admin Workspace is using version 1.9.0 or later.
• ServiceNow AI Platform® is using XP9, YP4, or later than YP4.
• The discovery.use.event.processing system property is turned on. For more information, see Configure Discovery to use Event Framework.

Role required: discovery_admin

About this task

When using a single queue, Cloud Discovery jobs frequently have higher priority than IP-based Discovery jobs. Separating Cloud-based and IP-based job queues helps avoid interference between Discovery types. However, balancing Discovery throughput and instance impact involves trade-offs.

Table 1. Instance impact based on queue configuration

Separate queues	Single queue
More worker threads, which means more database activity	Fewer worker threads, which means less database activity
More impact on jobs unrelated to Discovery	Less impact on jobs unrelated to Discovery
Cloud Discovery doesn't impact IP Discovery	Cloud Discovery can preempt IP Discovery

Procedure

1. Navigate to All > System Properties > All Properties.
2. In the System Properties [sys_properties] table, select the discovery.event.separate.cloud.events property.
3. Set the Value field to false.
4. Select Update.
