When setting up the subscription, Cygnus currently only accepts notifications in the older NGSI v1 format- the attrsFormat=legacy is therefore needed.

In your demo I’ve checked - you are connecting to a mongo DB - you are aggregating

docker run -it --network comet_demo_fiware_network --entrypoint /bin/bash mongo

mongo --host mongo_sth --port 27018

show dbs

admin 0.000GB config 0.000GB local 0.000GB sth_sensei_service 0.000GB

use sth_sensei_service

It looks the that your subscription is incorrect: { "entities": [ { "type": "PersonDetection", "isPattern": "false", "id": "PersonDetection" } ], "attributes": [ "ts" ], "reference": "http://sth:8666/notify" }

This means you are storing the ts attribute only.

Your request to comet is reading positionX and which has not been aggregated.

http://sth:8666/STH/v1/contextEntities/type/PersonDetection/id/PersonDetection/attributes/positionX

I hope this helps - you will need to alter your subscription - the attributes should be:

"attributes": [ “ts”, “posistionX” “positionY" ]

Ensure that you are running with logging to the max -I use the `CYGNUS_LOG_LEVEL=DEBUG` environment variable. Check that you are sending your notification to the right port - e.g. `CYGNUS_SERVICE_PORT=5050` would listen on "notification": {"http": { "url": "http://cygnus:5050/notify }}.

The notification.sh appears to be a simulation of the result of an Orion Subscription - and therefore needs to be posted to the port Cygnus is listening on - which is usually localhost:5050 - assuming you are running Cygnus on localhost.

Your couldn't connect to host message indicates that either you have not started Cygnus on localhost or you have configured an alternate port. Ensure you have used the environment variable CYGNUS_API_PORT=5080 somewhere or the agent.conf file holds a line cygnus-ngsi.sources.http-source.port = 5050

The subscription it is simulating is supposed to be something along the lines of When X occurs send a notification to cygnus - Therefore I'm guessing that localhost:5050 is the location where Cygnus is supposed to be listening.

When setting up a REAL subscription and running Orion it needs to be something like:

curl -X POST \ 'http://{{orion:port}}/v2/subscriptions/' \ -H 'Content-Type: application/json' \ -d '{ "description": "Notify Cygnus of all context changes", "subject": { "entities": [ { "idPattern": ".*" } ] }, "notification": { "http": { "url": "http://{{cygnus:port}}/notify" }, "attrsFormat": "legacy" }, "throttling": 5 }'

Replace {{orion:port}} and {{cyngnus:port}} as necessary (this assumes you are not using a fiware-header or fiware-servicepath yet...)

You can then update an existing entity with the PATCH command:

curl -X PATCH \ 'http://{{orion}}/v2/entities/<entity-id>/attrs' \ -H 'Content-Type: application/json' \ -d ' { "price":{"type":"Integer", "value": 89} }'

Obviously replace <entity-id> and the -d payload with your data.
