There were some other updates that were not done to the HPE one since it was removed in the cleanup. Why does it need to be readded? When looking at the previous code, it appears from the code and their docs that HPE is actually following the standard, so there wasn't a need to have an OEM-specific implementation added.

1. SubmitTestEvent is diffrent from my offered function:

• response status code is checked, so even if POST doe snot give an error, the response status code, maybe wrong. several responses are good.
• the payload field called Severity differs
• I want to sent the messageID, as in other vendors, its easier to compare, as all use it.
• EventTimestamp shoudl be RFC3339 format fro my testing.

2. test uses mock and actual captured responses

It sounds like all of that should be addressed in the core SubmitTestEvent implementation.

It would be good to add a Status Code check.

Severity is the same - it is a string according to the Redfish specification and that is what you have it defined as in this proposed change.

That would make sense to change the method signature to add the ability to pass in things like the MessageId.

The spec isn't entirely clear on expected timestamp format, but looking at what is in the spec there is an example request given that does show EventTimestamp formatted with an RFC3339 timestamp.
