[Fiware-lab-help] Orion CEP integration

[Daniele Stanzani]

Hi all,

i have some troubles integration Orion and CEP

Orion version:
Name        : contextBroker
Arch        : x86_64
Version     : 1.2.0
Release     : 1
Size        : 3.8 M
Repo        : installed
>From repo   : testbed-fi-ware
Summary     : Orion Context Broker
URL         :
http://catalogue.fiware.org/enablers/publishsubscribe-context-broker-orion-context-broker
License     : AGPLv3
Description : The Orion Context Broker is an implementation of NGSI9 and
NGSI10 interfaces.
            : Using these interfaces, clients can do several operations:
            : * Register context producer applications, e.g. a temperature
sensor within a room.
            : * Update context information, e.g. send updates of
temperature.
            : * Being notified when changes on context information take
place (e.g. the
            :   temperature has changed) or with a given frecuency (e.g.
get the temperature
            :   each minute).
            : * Query context information. The Orion Context Broker stores
context information
            :   updated from applications, so queries are resolved based on
that information.

CEP version: the one installed with the image cep-r3.3.3-img
