When using the redfish LogServices/Event uri (“/redfish/v1/Systems/1/LogServices/Event/Entries?$expand=.”) to read the event entries, if the event has a "MessageId": "iLOResourceEvents.1.4.AggregateHealthStatusChange", fields are missing. There should be fifteen fields based on:https://servermanagementportal.ext.hpe.com/docs/redfishservices/ilos/ilo6/ilo6_170/ilo6_msgregs170#iloresourceevents.1.4.aggregatehealthstatuschangeHowever, depending on the server, there could be ten-thirteen arguments. The missing fields vary from server to server; hence, this record is useless.Example:"EventTimestamp": "2025-10-11T12:51:24Z","Links": {"OriginOfCondition": {"@odata.id": "/redfish/v1/Systems/1"… Example of a 13 argument, when there should be 15, the results are missing 2 fields."Message": "AggregateServerHealth is %1,...."MessageArgs": ["OK","OK","Redundant","OK","OK","Unknown","OK","False","Redundant","OK","OK","OK","OK"],"MessageId": "iLOResourceEvents.1.4.AggregateHealthStatusChange","Name": "Event","OemRecordFormat": "Hpe-Event","Severity": "OK"When any Health Status value is unavailable, the records stored in the alert database will omit that field. In the above case, this server does not have any Liquid cooling; therefore, those fields have been dropped, shifting everything up by two. Instead, it should be as follows:"MessageArgs": [ if all 15 fields are there"OK","OK","Redundant","OK","", <<<< LiquidCoolingRedundancy is blank"",<<< LiquidCooling is blank"OK", << now everything is in line"OK","OK","False","Redundant","OK","OK","OK","OK"],It should be noted that missing fields will vary depending on which values are available. During boot, the message may be missing anywhere between two and seven values.
