Please, ANSWER this question AT https://stackoverflow.com/questions/54220061/orion-subscriptions-do-not-detect-the-removal-of-entities
Question:
Orion subscriptions do not detect the removal of entities
Description:
Subscriptions detect the creation and update of entities but do not detect the removal of entities.
Subscription creation:
POST http://myhost:orion_port/v2/subscriptions
{
"description": "Send a notification to detect any change",
"subject": {
"entities": [
]
},
"notification": {
"http":
}
}
Entity creation:
POST http://myhost:iot_aget_json_port/iot/devices
{
"devices": [{
"device_id": "entity_test_agent",
"entity_name": "entity_test_orion",
"entity_type": "test",
"transport": "HTTP",
"protocol": "IoTA-JSON",
"attributes": [
],
"static_attributes": [
]
}]
}
Entity update:
PUT http://myhost:orion_port/v2/entities/entity_test_orion/attrs/name
{ "value": true }Delete entity:
DELETE http://myhost:orion_port/v2/entities/entity_test_orion
DELETE http://myhost:iot_aget_json_port/iot/devices/entity_test_agent
First, I send the subscription creation to detect changes in entities.
Later, I create an entity and the subscription is executed without problems. Then I update the entity name and I receive the subscription again perfectly, but if I delete the entity I do not receive any event.
There are any way to receive subscription events to detect when an entity is deleted?
