A phrase. You can specify that the search results contain a specific phrase.	`"cat food"` (quotation marks)	Topics that contain the literal phrase "cat food" and all its grammatical variations. Without the quotation marks, the query is equivalent to specifying an OR operator, which finds topics with one of the individual words instead of the phrase.

How to Use OpenStack Event Discovery

This task includes the following steps:

Prerequisite – Configuration in OpenStack

Enable notifications in Nova. Make sure that the following configuration exists in nova.conf (/etc/nova/nova.conf) and restart Nova-related services.

[DEFAULT]
notification_topics=notifications notification_driver=messagingv2
Prerequisite – Configuration in UCMDB
- Create a new AMQP protocol for the AMQP server.
  
  For details on how to create a protocol, see the Protocol Parameter Dialog Box section in the Universal CMDB Data Flow Management section of the UCMDB Online Help document.
  
  For credential information, see Supported Protocols.
- Add the IP address of the AMQP server to the Range of Data Flow Probe.
  
  For Range information, see the New/Edit Range Dialog Box section in the Universal CMDB Data Flow Management section of the UCMDB Online Help document.
Run the discovery
1. Run the Range IPs by ICMP job to discover IP addresses.
2. Run the Manual AMQP for OpenStack job to discover the AMQP server that is used by OpenStack.
  
  Note You need to first click Add CI in the Discovery Progress pane to add the IpAddress CI that belongs to the AMQP server and then activate the Manual AMQP for OpenStack job.
3. Wait until the Manual AMQP for OpenStack job is finished. Messaging Server CI should be discovered.
4. Run the OpenStack Event Monitor job to monitor events from the AMQP server.
5. Wait for OpenStack events.
Note The Manual AMQP for OpenStack and OpenStack Event Monitor jobs only work on Jython 2.7 that is bundled with UCMDB 10.22 or later. This is because the driver of the AMQP protocol only supports Jython 2.7.

For details on running jobs, refer to "Module/Job-Based Discovery" in the Universal CMDB Data Flow Management section of the UCMDB Online Help.
