Use Case: Get IMSI with no traffic in the last 7 days
This use case shows how to retrieve data and SMS traffic produced by a given enterprise within the last 7 days, also identifying those IMSI that did not perform any traffic in such time frame. The last info could be used for troubleshooting purpose.
The use case is realized by implementing a sample application flow in NodeRed® and Postman. The sample flows are available and downloadable from the "Available resources" section of this page.
The flow exposes a new API: "Get IMSI with no traffic", which includes some parameters of the native APIs of IoT Accelerator to facilitate their usage.
| API exposed by the sample flow | Get IMSI with no traffic in the last week |
| Method | GET |
| IoT Accelerator APIs in scope | |
| Endpoint | http://localhost:1880/get_aggregrated_traffic/last_week?customerNo=<CUSTOMERNO> |
| Headers |

| Parameters | customerNo - a string value that denotes the customer number |

ERROR RESPONSES
It might happen during traffic peak period that the rate limit control of the API used in this use case errors could be reached.
In such a condition, the Node-RED flow will return an HTTP 500 status code, with the following message indicating for which API the limit was reached:
{"Generic Error. Bad response from API "}
No retry schema have been implemented in this sample use case.
