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.

Performance Dashboard and Performance Engine

The Performance Dashboard in OMi enables you to visualize system metrics and custom application metrics in the form of performance dashboards. You can use out-of-the-box dashboards, as well as create custom performance dashboards for the Configuration Items (CIs) that you are monitoring. OMi Performance Dashboard works with the following data sources to visualize performance metrics as dashboards:

Operations Agent
SiteScope
Operations Connector
OpsBridge Store (provided by OMi Performance Engine)
Application Performance Management (APM)
Cloud Optimizer

The Performance Engine is an add-on component of Operations Manager i that provides streaming of custom metrics and system metrics in a large scale environment. OMi Performance Engine aggregates streamed data from Operations Agent or Operations Connector which receive data using the RTCM-REST Web Service interface. OMi Management Packs also use the Operations Agent REST WebService interface to submit metrics data for metric streaming. You can visualize the metric data in the OMi Performance Dashboard by using the OpsBridgeStore data source. OMi Performance Engine stores 720 points of data for a metric. If the collection and forwarding interval is configured for 5 seconds, the cache will hold 1 hour of data. The metric data is stored for one hour and can be displayed as real-time data in the OMi Performance Dashboard. If a Vertica database is installed and configured, you can also store metrics for longer than an hour and display them in the OMi Performance Dashboard.

OMi Performance Dashboard and OMi Performance Engine provide the following capabilities for users:

Visualize, investigate, and review the performance of specific system infrastructure metrics as well as custom application metrics in real-time.
Aggregate and stream custom metric data and system metric data for more than 25000 datapoints/sec from managed nodes.
OMi Performance Engine can be installed separately on an additional server to support additional real-time data sources and thus provides a scalable environment.
Share existing Vertica database available with OpsBridge Reporter for additional data retention for more than one hour.
