> +Question:+
> Error subscription in cygnus
> +Description:+
> I am having problems when creating a subscription in cygnus.
> I really think the error is from the contextBroker since it appears in the log - this is the information that it shows:
> Time = 2017-08-07T10: 48: 09.360Z | Lvl = WARN | Corr = N / A | Trans = 1502101560-775-00000000006 | From = pending | Srv = pending | Subsrv = pending | Comp = Orion | Op = AlarmManager.cpp [328]: notificationError | Msg = Raising alarm NotificationError http: // localhost: 5050 / notify: (
> Easy_perform failed: Could not connect to server)
> I have open ports.
> My subscription status is failed.
> How can I solve that?
> EDIT
> The creation is as follows:
> {
>   "description": "A subscription to get info about Room1",
>   "subject": {
>     "entities": [
>       {
>         "id": "Room1",
>         "type": "Room"
>       }
>     ],
>     "condition": {
>       "attrs": [
>         "pressure"
>       ]
>     }
>   },
>   "notification": {
>     "http": {
>       "url": "http://localhost:5050/notify"
>     },
>     "attrs": [
>       "temperature"
>     ],
>     "attrsFormat": "legacy"
>   }
> }
> When I perform the subscription on fiwarelab in the orion machine already created if it works, but when I try on a machine centos 6 and performing the installation steps is when I get that error.
> I have already solved the problem and it was setup.
> The steps I followed with the following:
> To install cygnus:
> 1st install java and maven as it puts on the web of fiware
> 2nd install with yum install cygnus
> 3º Install apache flume as it puts on the web of fiware
> 4th install mySQL
> 5th configure the agents
> Everything works already.
