Release All currently supported releases. Cause Application CIs depend on a parent CI, the main CI which is independent. Dependent CIs are identified using dependent identifiers. The parent identifier for different application classes is the "Application Rule" identifier. An identifier may be configured to fallback to a parent identifier before attempting to insert a new CI. The OOB "Application Rule" uses fields "Running process command", "Running process key parameters", and "Class" to find matches. It is possible that multiple applications on the same host have the same "Running process command", "Running process key parameters", and "Class". The OOB "Application Rule" therefore would not be a good identifier to fallback to if this is acceptable or expected for such application being discovered. This would lead to only one such application being created per parent CI. To confirm the "Application Rule" is being used: Collect the input payload passed to the identification engine, will be available in the ecc_queue input used by the pattern.Navigate to "Configuration > Identification/Reconciliation > Identification Simulation".Select "Start with Existing Payload".Select "ServiceNow" source, paste payload, and click execute.Review "Output" section to see rules used by the identification engine. Example output: Output Payload :{ "items": [ { "className": "cmdb_ci_linux_server", "operation": "UPDATE", "sysId": "edb652ca133837403ece70404244b085", "identifierEntrySysId": "Unknown", "identificationAttempts": [] }, { "className": "cmdb_ci_db_db2_instance", "operation": "UPDATE", "sysId": "789a52ce133837403ece70404244b045", "identifierEntrySysId": "8985a23ec3f00200d8d4bea192d3ae08", "identificationAttempts": [ { "attemptResult": "NO_MATCH", "identifierName": "DB2", "attributes": [ "db_name", "installed_dir", "sys_class_name", "tcp_port" ], "searchOnTable": "cmdb_ci_db_db2_instance" }, { "attemptResult": "SKIPPED", "identifierName": "Database instance rule", "attributes": [ "serial_number" ], "searchOnTable": "cmdb_ci_db_instance" }, { "attemptResult": "SKIPPED", "identifierName": "Database instance rule", "attributes": [ "edition", "name", "tcp_port" ], "searchOnTable": "cmdb_ci_db_instance" }, { "attemptResult": "SKIPPED", "identifierName": "Application Rule", "attributes": [ "cl_port", "sys_class_name" ], "searchOnTable": "cmdb_ci_appl" }, { "attemptResult": "MATCHED", "identifierName": "Application Rule", "attributes": [ "running_process_command", "running_process_key_parameters", "sys_class_name" ], "searchOnTable": "cmdb_ci_appl" } ] } ], "relations": [ { "className": "cmdb_rel_ci", "operation": "NO_CHANGE", "sysId": "7c9a52ce133837403ece70404244b049", "identifierEntrySysId": "Unknown" } ]} Resolution Create a dependent identifier for the CI class if there isn't already one.Set the "Allow fallback to parent's rules" to false for the identifier/identifier rules being used for such CI, in the previous example identifier for cmdb_ci_db_db2_instance.
