Experimenting with Redfish Event Subscription

Config files

Copy config.yaml.example to config.yaml and modify the BMC settings and the IP address for the receiver endpoint.

Data dumper

dump/main.go shows some settings for the BMC, including existing event subscriptions.

go run ./dump/main.go

Receiver

receiver/main.go is a web server that dumps the event notifications to the console. To run it

First, use make_certs.sh to generate certificates (you may need to modify openssl.conf to change the hostname for the certs).
Then run
```
go run ./receiver/main.go
```

Register the receiver

register/main.go configures the BMC to send events to the receiver service.

go run ./register/main.go

Testing

After the receiver is registered, using the dumper should trigger a login event notification. The output on the console will look something like this.

$ go run ./receiver/main.go
listening on https://10.8.1.133:9090

The web UI for the BMC also includes a way to send test events. The input must be a valid message ID, as defined by the hardware. One value that works for Dell is CPU0001.

Cleaning up

unsubscribe/main.go removes a subscription from the BMC. Use the dumper program to get the URI, then pass it on the command line.

go run ./unsubscribe/main.go /redfish/v1/EventService/Subscriptions/f35299c0-25ed-11eb-a058-588a5afa1cc4
