Connecting Cepheus to Orion

asked 2018-06-05 20:23:17 +0200

Dear Fiware Support Team,

I am having the following issue:

I want to connect Cepheus to Orion (Orion as a source of events), process some queries and return new events to Orion (this time as destination). Like depicted below:

I have tried to configure Cepheus towards this goal, with the following example configuration:

{
  "host": "http://localhost:8080",
  "in": [
    {
      "type": "PersonDetection",
      "id": "PersonDetection",
      "providers": [
        {
          "url": "http://orion:1026",
          "serviceName": "==SERVICE_NAME==",
          "servicePath": "==SERVICE_PATH=="
        }
      ],
      "attributes": [
        {
          "name": "tagId",
          "type": "Integer"
        },
        {
          "name": "sectorId",
          "type": "Integer"
        },
        {
          "name": "positionX",
          "type": "Float"
        },
        {
          "name": "positionY",
          "type": "Float"
        },
        {
          "name": "ts",
          "type": "Timestamp"
        }
      ]
    }
  ],
  "out": [
    {
      "id": "CellDetection",
      "type": "CellDetection",
      "attributes": [
        {
          "name": "cellId",
          "type": "Integer"
        },
        {
          "name": "tagId",
          "type": "Integer"
        },
        {
          "name": "ts",
          "type": "Timestamp"
        }
      ]
    }
  ],
  "brokers": [
    {
      "url": "http://orion:1026",
      "serviceName": "==SERVICE_NAME==",
      "servicePath": "==SERVICE_PATH=="
    }
  ],
  "statements": [
  ]
}

With this configuration I want Cepheus to receive "PersonDetection" events (then run some query) and emit "CellDetection" events.

However when Orion emits "PersonDetection" events, I see no logs in the Cepheus console. Which probably means that he's not receiving any events, maybe because he did not subscribe to Orion properly.

The only logs generated by Cepheus are the following:
