}The reporter feeds the data to the API via the /report/ endpoint:
POST /report/

"status": "free",
"timestamp": "2000-01-01T00:00:00.000000000+01:00",
"lab": "Tootil 0"
},
"e-c07kilf903.it.manchester.ac.uk": {
"status": "used",
"timestamp": "2000-01-01T00:00:00.000000000+01:00",
"lab": "Tootil 0"
}
}
Will return a 200 OK and the state will be updated
You need two components, one is the API which caches the status of the machines and returns the info (/pull), and the remote part which pushes the information from the network to the API (/push)
To build them you run:
go build -o out/pull pull/main.go
go build -o out/push push/main.go
To run the push, you do:
./out/push <path/to/logs>
To run the API, you do:
./out/pull
