Chapter 34. Setting up and evaluating the 3scale response codes log for your API

To see how your clients are using the API, and see in real time if your servers are running as expected, set up and use the response codes log in 3scale.

Procedure

  • Set the APICAST_RESPONSE_CODES environment variable to 1 or true when starting the APIcast gateway that uses Docker or an OpenShift deployment. This enables response code tracking.

Example

When enabled, APIcast gateway captures the HTTP status code of API responses returned by the upstream service for authorized calls, and sends them to the Service Management API (in authrep call). Example:

https://su1.3scale.net/transactions/authrep.xml?service_token={SERVICE_TOKEN}&service_id={SERVICE_ID}&user_key={USER_KEY}&usage%5Bhits%5D=1&log%5Bcode%5D=200"

In this example,log[code]=200 is sent, which means that the API responded with a 200 status code.

Verification

To verify the integration, perform a call to your API product with valid 3scale credentials, and then verify that the call was correctly reported on the Analytics > Usage page.

Usage screen

If everything is going well so far, go to the Analytics >Response codes page. You should be able to see a graph with your latest traffic divided by colors, depending if the response was 2xx, 4xx, or 5xx.

response codes screen

The graph tool gives you the ability to view the history of response codes. You can also check the response code statistics for different periods of time and different levels of granularity. Click the time selection bar and define the time period and granularity that meets your needs.
