Retrieving metrics from Azure API Management Service:
There are two primary methods for retrieving metrics from Azure API Management Service using Azure SDK: Requests and Insights. Each method has its own advantages and limitations. Choose the method as per your requirement.
| Method | Description | Limitations |
|---|---|---|
| Requests | The agent uses the reports().listByRequest method to retrieve all requests for the specified time interval. The agent builds API Control Plane compatible metrics such as transactionsCount, averageLatency, and averageResponseTime, categorizing them according to the status code 2xx, 3xx, 4xx, and 5xx before sending them to API Control Plane. |
If high volume of transactions occur within the specified time interval, retrieving the data may lead to performance issues in the agent. |
| Insights | The agent uses reports().listByTime or reports().listByApi method to retrieve aggregated metrics data in 15 minute time intervals (15, 30, 45). | This method does not categorize the data according to the status code. |
