Step to recreate:

1. Subscribe to Push style events using RedfishEventListener_v1.py

   
   Method = POST, status = 201, expected status = [200, 201, 204] 
   {
   "@Message.ExtendedInfo": [
   {
     "@odata.type": "#Message.v1_0_0.Message",
     "Message": "The resource has been created successfully",
     "MessageArgs": [],
     "MessageId": "Base.1.8.1.Created",
     "MessageSeverity": "OK",
     "Resolution": "None"
   }
   ]
   }

-bash-4.2$ curl -k -H "X-Auth-Token: $bmc_token" -X GET https://${BMC_IP}/redfish/v1/EventService/Subscriptions/ { "@odata.id": "/redfish/v1/EventService/Subscriptions", "@odata.type": "#EventDestinationCollection.EventDestinationCollection", "Members": [ { "@odata.id": "/redfish/v1/EventService/Subscriptions/955021906" -- A subscription is created. } ], "Members@odata.count": 1, "Name": "Event Destination Collections"

2. Execute "reboot" command on BMC
3. Check the subscription after BMC reboots.  

}-bash-4.2$ curl -k -H "X-Auth-Token: $bmc_token" -X GET https://${BMC_IP}/redfish/v1/EventService/Subscriptions { "@odata.id": "/redfish/v1/EventService/Subscriptions", "@odata.type": "#EventDestinationCollection.EventDestinationCollection", "Members": [], "Members@odata.count": 0, -- Subscription is deleted "Name": "Event Destination Collections" }-bash-4.2$

Possibly related to this: https://github.com/openbmc/bmcweb/issues/165

It's not clear all the version information and other things were handled on the evenservice persistent file. It just needs rolled into the main one.

@edtanous This issue is for https subscription only. On BMC reboot, the exisiting subscription does not persist. Issue #165 talks about being unable to subscribe to event notification itself using http.

Is this still an issue? The eventservice code has changed significantly in the last few years.
