That first example definitely doesn't return "hostname required", though the others all *should*, because they don't have a hostname.

The first example works fine for me if provided with a valid hostname:

root@zeta:/home/observium/dev# curl -u derp:derp http://dev.observium.org/api/v0/devices/ -H "Content-Type: application/json" -X POST -d '{"hostname":"<derp>"}'

{"status":"ok","device_id":773}

root@zeta:/home/observium/dev#

Trying to add a device :-

I have tried the following incantations :-

curl -u admin:PASSWORD http://observium.riksbyggen.intra/api/v0/devices/ -H "Content-Type: application/json" -X POST -d '{"hostname":"papp01-exo"}'

curl -u admin:PASSWORD http://observium.riksbyggen.intra/api/v0/devices/ -H "Content-Type: application/json" -X POST -d '{"papp01-exo":"localhost"}'

curl -u admin:PASSWORD http://observium.riksbyggen.intra/api/v0/devices/ -H "Content-Type: application/json" -X POST -d '{"papp01-exo":"observium.riksbyggen.intra"}'

curl -u admin:POSSWORD http://observium.riksbyggen.intra/api/v0/devices/ -H "Content-Type: application/json" -X POST -d '{'papp01-exo':'observium'}'

all of which return "Hostname Required"
