The following requirements should be fulfilled before the execuation of Analytics service.
1. A virtual enviornment exist with all the required packages listed in [requirements.in](https://labs.etsi.org/rep/tfs/controller/-/blob/develop/src/analytics/frontend/requirements.in) sucessfully installed.
2. Verify the creation of required database and table. The
[Analytics DB test](https://labs.etsi.org/rep/tfs/controller/-/blob/develop/src/analytics/tests/test_analytics_db.py) python file lists the functions to create tables and the database.
3. The Analytics backend service should be running.
4. All required Kafka topics must exist. Call `create_all_topics` from the [Kafka class](https://labs.etsi.org/rep/tfs/controller/-/blob/develop/src/common/tools/kafka/Variables.py) to create any topics that do not already exist.

4. There will be an input stream on the Kafka topic that the Streamer class will consume and apply a defined thresholds.
- A JSON encoded string should be generated in the following format:
```
'{"time_stamp": "2024-09-03T12:36:26Z", "kpi_id": "6e22f180-ba28-4641-b190-2287bf448888", "kpi_value": 44.22}'
```
- `kpi_value` should be float or int.
- The Kafka producer key should be the UUID of the Analyzer used when creating it.
- Use the following Kafka topic to generate the stream: `KafkaTopic.ANALYTICS_RESPONSE.value`.
- Generate the stream on the following Kafka topic: `KafkaTopic.ANALYTICS_RESPONSE.value`.
## Steps to create and start Analyzer
The analyzer can be declared as below but there are many other ways to declare:
The given object creation process for `_create_analyzer` involves defining an instance of the `Analyzer` message from the [gRPC definition](https://labs.etsi.org/rep/tfs/controller/-/blob/feat/194-unable-to-correctly-extract-the-aggregation-function-names-from-the-dictionary-received-as/proto/analytics_frontend.proto) and populating its fields.

......@@ -101,18 +97,5 @@ analytics_client_object = AnalyticsFrontendClient()
analytics_client_object.StartAnalyzer(_create_analyzer_id)
```
### **How to Receive Analyzer Responses**
- There is a non-gRPC method in the analyzer frontend called `StartResponseListener(<analyzer_uuid>)`. The `analyzer_uuid` is the UUID of the analyzer provided when calling `StartAnalyzer()`. The following code will log the responses:
```python
from analytics.frontend.service.AnalyticsFrontendServiceServicerImpl import AnalyticsFrontendServiceServicerImpl
analytic_frontend_service_object = AnalyticsFrontendServiceServicerImpl()
for response in analytic_frontend_service_object.StartResponseListener(<analyzer_uuid>):
LOGGER.debug(response)
```
### **Understanding the Output of the Analyzer**
- **Output Column Names**: The output JSON string will include two keys for each defined threshold. For example, the `min_latency` threshold will generate two keys: `min_latency_THRESHOLD_FAIL` and `min_latency_THRESHOLD_RAISE`.
- `min_latency_THRESHOLD_FAIL` is triggered if the average latency calculated within the defined window size is less than the specified threshold range.
- `min_latency_THRESHOLD_RAISE` is triggered if the average latency calculated within the defined window size exceeds the specified threshold range.
- The thresholds `min_latency_THRESHOLD_FAIL` and `min_latency_THRESHOLD_RAISE` will have a value of `TRUE` if activated; otherwise, they will be set to `FALSE`.
### **How to Receive Analyzer Response**
- `GetAlarms(<kpi_id>) -> KpiAlarms` is a method in the `KPI Value Api` that retrieves alarms for a given KPI ID. This method returns a stream of alarms associated with the specified KPI.
