Multiple CI Matching

Multiple CI Matching - Example 1

The following example demonstrates how the Data-In service matches multiple with different identification criteria where there are no conflicts.

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)`

The input bulk data is received.

The service identifies matching CIs in the CMDB

In this example, the input node matches four nodes in the CMDB having different identification criteria.

The service merges the input CI with each matching CI in the CMDB.

The service checks for conflicts between the resulting merged CIs.

Nodes N2, N3, and N4 are the same CI; therefore, it is obvious that there is no conflict between them. The only difference between nodes N1 and N2 is the additional MAC address in N1. Since the MAC address match validation criterion uses the contains operator, there is no conflict between nodes N1 and N2 either.

Conclusion: There are no conflicts with any of the CMDB matching nodes.

Decision: The Data-In service merges all of the CIs into one CI.
