How to key Protocol when create subscription with rf_event_service.py

[FelixD999]

Hi, As far as I know Destination and Protocol are necessary to create a subscription, but I don't know how to enter the value about Protocol when creating the subscription. Not sure if the failure to send the command is related to missing necessary parameters.

Attached the request body about creating Subscription via Redfish: { "Context": "Event_Sub", "Destination": "https://192.168.0.110:4443", "Protocol": "Redfish", "EventFormatType": "Event", "ResourceTypes": [ "EventService", "Systems", "AccountService", "TelemetryService", "Chassis", "Managers", "TaskService" ], "RegistryPrefixes": [ "EventLog", "IPMI", "HttpStatus", "SyncAgent", "Security", "Base", "Task" ] }

Thanks, Felix

Right now the tool automatically puts in "Redfish" for you; it's not provided as an option.

This is where the payload is built for the subscription request: https://github.com/DMTF/Redfish-Tacklebox/blob/79878d00a7885cf5742c4995bd10186bf9b1b879/redfish_utilities/event_service.py#L187

It starts with just the provided destination and fills in Protocol to always be Redfish, then optionally fills in other properties based on whatever else is provided by the user.

If you add --debug to the script input, it'll produce a log file with HTTP traces to show exactly what is sent/received.

But at least from the error message on the console, it looks like either EventTypes isn't supported by the service or one of the values provided isn't supported.

It's also possible you're hitting an old bug from a few years ago where the tool was always sending "EventTypes" as part of the payload. Given your sample script input, you're clearly not specifying EventTypes.

Can you check your version of Tacklebox? The issue I'm thinking of was fixed in 1.2.9.

Thanks for your help and answers! I checked the version is the latest "3.2.3" and code also have be fixed but still have error message.

[mraineri]

Can you try with --debug and provide the .log file generated?

[FelixD999]

I refer the --help info, but I'm not sure how to add --debug correctly, Could you help correct me?

[mraineri]

Are you sure you have the latest version of the tool? It looks like you're using an older version. With how you're invoking the tool, it will run from the installation and not from the source code you've checked out.
