Population Flow

The following stages comprise the flow of populating UCMDB with CIs from ServiceNow:

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)`

Querying CIs

The integration job reads the mapping files to identify which CIs and relationships should be pulled from ServiceNow. It then connects to ServiceNow's Web Service API.

A SOAP client is created for each CI type and relationship type defined in the mapping file, for example, https://demo.service-now.com/cmdb_ci_unix_server.do?wsdl.
The getRecords([query]) method is invoked to obtain instances of this CI type or relationship.

Mapping data

CIs that are obtained from ServiceNow are mapped to UCMDB CIs.

Querying relationships

The integration job uses https://demo.service-now.com/cmdb_rel_type.do?wsdl and https://demo.service-now.com/cmdb_rel_ci.do?wsdl to link CIs.

Sending topology to UCMDB

The topology is sent from the Data Flow Probe to UCMDB.
