Could not find host item in Identification engine output payloadDescriptionPattern discovery of infrastructure or application CIs fails with error "Could not find host item in Identification engine output payload."Release or EnvironmentAllCauseA "valid" host is not found in the pattern payload (the data returned by the pattern), or MID property mid.discovery.max_ci_count_per_page is set to a value lower than the default (500). The following class throws the error:HorizontalDiscoveryResultHandler.java The following class determine what is "acceptable" as a host:ClassModel.java Property found on class:GlidePropertiesConstants.java Method analyzeIdentificationEnginePayload:1- Gets the main CI type which will be listed in the payload. If not listed in the payload it will get from the pattern CI type.2- Checks if the main CI type is a "valid" host type via ClassModel.java3- ClassModel.java checks what are the possible hosts. Possible hosts are records which extend one of the following tables (cmdb_ci_unix_cluster does not):boolean isHost = isInstanceOf(sysClassName, CMDB_CI_HARDWARE) || isInstanceOf(sysClassName, CMDB_CI_LOGICAL_DATACENTER) || isInstanceOf(sysClassName, CMDB_CI_CLOUD_LOAD_BALANCER);4- Falls back to checking if the class is listed in property sa.host_classes, if not the main ci type here is not a possible host. Thus hosts are empty and the error is thrown.ResolutionReview the ecc_queue input payload and find the "mainCiType".Confirm the mainCiType is a table which extends one of the following tables, ViewTheSchemaMap:CMDB_CI_HARDWARE, CMDB_CI_LOGICAL_DATACENTER, CMDB_CI_CLOUD_LOAD_BALANCERIf the mainCiType table is not extended from one of the above tables, create system property sa.host_classes set to type "string" and value equal to the mainCiType. OR Revert MID property mid.discovery.max_ci_count_per_page back to the default value of 500.Additional InformationIRE Identification DUPLICATE_PAYLOAD_RECORDS error
