Overview of Redfish Eventing for iDRAC alerts
6 Manage iDRAC alerts by using the Redfish Eventing feature in YX3X and later PowerEdge servers
Overview of Redfish Eventing for alerts
Redfish Event Service supports two styles of subscription.
• Push Style Eventing (HTTP POST)
• Server Sent Events (SSE)
Note—SSE is supported from iDRAC9 v4.00.00.00 and later versions.
1.1 SNMP traps vs Redfish alerts
SNMP traps and/or Redfish alerts can be used for asynchronous event reporting. Both are supported in
iDRAC.
Push style
Eventing
• When the alert is generated in iDRAC, Redfish
Event service uses an HTTP POST to push the alert
events to the subscribed Redfish client.
SSE style
Eventing
• The Redfish client starts an SSE connection to the
iDRAC Redfish Event service by performing a GET
operation on the SSE URI to receive the alert
events generated in the iDRAC.
