Aftre paying with temperature thresholds for simulating alerts I found that redfish interface actually support possibility to privide active list of alerts via this URL: /redfish/v1/Managers/iDRAC.Embedded.1/LogServices/FaultList/Entries So, when I set max temperature threshold lower then current temperature, alert with message id TMP0120 was visible under this URL, when recovered the threshold value, it is disapiared. But why dosn't it described at all in any DELL documentation? Who does know if I really can rely on this FaultList? Will it contains all kind of statefull alerts?
It is possible to configure SNMP traps to get alerts or cofigure eventService or mail notification and so on, but if a management station is just started or connected, is any way to get list of active alarms from Dell EMC PowerEdge R640&R740 (from IDRAC 9)?
