Discovery Event Manager rules

Discovery Event Manager processing is governed by rules that define what actions Discovery Event Manager will perform when the actual state of an incoming configuration item (CI) record differs from the managed state of a CI record in ITSMA Service Management.

During initial configuration of Discovery Event Manager, you start with a basic set of rules for Change Management. You can refine those rules as necessary. Each rule identifies a series of checks that Discovery Event Manager processes whenever a CI record is received from Web services. Depending on the rule, Discovery Event Manager may add or delete the record, open a change, log the information, or update the record's status.

Service Management opens a change or incident based on the settings defined in the populateChange or populateIncident function in the discoveryEvent ScriptLibrary record. You can override the default settings by writing a custom JavaScript on the Change Customization or Incident Customization tab.
