Just-In-Time Discovery Overview

Universal Discovery integrates with RUM to provide real time, passive discovery and monitoring of topology changes in a given environment. This is known as the Just-In-Time (JIT) discovery mechanism.

One or more RUM Engines can be configured to interact with Universal Discovery's Data Flow Probes. The RUM Engine gathers information from RUM Probes in its network, and passes relevant information on to the Data Flow Probes. From the Universal Discovery perspective, the RUM Engines behave as passive discovery probes, where the Data Flow Probes are the active probes.

The passive probes also send notifications about discovered information to the Data Flow Probes. Notifications can include, for example, changes in environment topology, such as an unseen IP address, or software that is not running. You configure these notifications in Universal Discovery. Based on these notifications, the Data Flow Probes report, add, or remove relevant CIs to or from the UCMDB Server, or designate them as candidates for deletion.

Search for	Example	Results
A single word	`cat`	Topics that contain the word "cat". You will also find its grammatical variations, such as "cats".
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.

Search for	Operator	Example
Two or more words in the same topic	`AND` `and` `+` (plus symbol) `&` (ampersand)	`cat AND dog` `"cat food"+milk` `"cat food"&"dog food"`
Either word in a topic	`OR` `or` `\|` (pipe)	`cat OR dog` `cat \| dog`
Topics that do not contain a specific word or phrase	`NOT` `not` `!` (exclamation point)	`NOT cat` `! dog`
Topics that contain one string and do not contain another	`^` (caret)	`cat ^ mouse`
A combination of search types	`( )` parentheses	`cat + (dog \| mouse)` `cat \| dog + (! mouse)`
