This guide documents analytics with Red Hat 3scale API Management 2.4.

Chapter 1. Exporting Analytics

This article shows how to create scripts that extend the current capabilities of the built-in 3scale analytics.

By using the Account Management and Analytics API (Enterprise only), you can create scripts that get the custom information that you need in the format that you prefer. This article describes a particular use case, but the same approach can be used to get whatever data you need out of 3scale.

1.1. Why DIY?

3scale continously improves the features available on your API Admin Portal. However, you may be ahead of our developement plans and have a very specific need that’s not yet supported.

Luckily for you, there is a way around this potential frustration because 3scale always gives you the tools to access all your data. The mantra is: what 3scale does not do yet, you can always do yourself.

DIY has some costs – it takes some resources to write the scripts – but the cost is not too high, as we will show in this article. More importantly, DIY gives you total flexibility and control to implement any use case you can think of.

1.2. A real-world example

Recently a customer came to us with a very specific need that could not be solved with 3scale in a streamlined way.

They were onboarding thousands of new developers per week, which was fantastic news! They were able to survive such success thanks to the 3scale API Management Platform. Onboarding so many developers would be a daunting task – luckily 3scale provides automates necessities such as key provisioning, sign-up workflows, and email communication. So far so good.

There was, however, something that was not possible to do with 3scale, which was quite important for them. Since they are onboarding so many people, they needed a straight-forward way to classify the new developers based on their engagement with their API so that their operations and marketing teams could interact with the new developers more effectively.

Such a feature, at least at the required level of detail, is not yet available in 3scale’s built-in analytics tools. However since all the data is already available, it can be extracted using 3scale’s Account and Analytics API.

1.3. What kind of insight did the customer want?

They would like to know how many new developers have signed up for the free evaluation plan in the last 10 days, split up different ways.

First, they wanted to know how many developers signed up but didn’t ever use their API. What they wanted to do with this information is out of scope for this article, but it’s clearly valuable information that would help adoption of your API.

Second, they wanted to split the developers that had used their API into two groups:

  • Developers that used it for a period of time – say the first half of the 10 days – and then stopped using the API. These developers tried it out, but became inactive.
  • Developers that have been using the API consistently. For those, they would like to know the percent growth (or decline).

This information is available on 3scale’s built-in analytics. The problem is that there is no view to show it aggregated, which makes the whole experience quite cumbersome.

A typical answer to this problem would be this classification will be part of the upcoming analytics revamp. (Funny thing is that’s actually the case.) But that does not solve the problem if you need it now. We at 3scale want to give you the tools to do everything you need to do without depending on our release schedule.

1.4. Hands-on implementation

1.4.1. Winning recipe

This recipe usually gives better results in achieving custom work.

  • Tinker a bit with ActiveDocs. 3scale ActiveDocs, available in your Admin Portal, under the Account Settings (Gear icon in the top right corner) > Integrate > 3scale API Docs. 3scale has all of its APIs available as ActiveDocs so that you can try them out from your browser. This allows you to find the request that best serves your needs, get the request (curl-like) and get a grasp of the response. See an example…​

    DIY Analytics

This is the ActiveDocs for the API request to fetch all applications that will be used on the script to extend the analytics.

  • Once you’ve done the research with the ActiveDocs, put down the request on your scripting language of choice (ours is pedestrian Ruby). Thanks to the request and responses provided by ActiveDocs, it has never been easier to explore what the API does.
  • Repeat until you have a script that does exactly what you need. For the example of the extended analytics, the script is available as a gist. You can try it out in your account.

As pedestrian as it sounds, this is the easiest way to proceed. The ActiveDocs let you quickly get a grasp of what the API is able to do. Then, it’s just a matter of finding which 3 or 4 requests are needed for the task you want to do and putting a script together.

1.4.2. Step-by-step guide

These were the steps taken to achieve the custom analytics that this customer wanted:

  • Retrieve the full list of applications. This operation requires pagination, but as you can see, it’s dead simple.
def api_call_applications_list(domain, provider_key)
  done = false
  res =
  page = 1

      while !done
    url = "https://#{domain}/admin/api/applications.xml?provider_key=#{provider_key}&page=#{page}&per_page=100"
    page += 1
    response = RestClient.get url
    raise"Wrong response code (#{response.code}) in request #{url}") if response.code!=200
    document = Nokogiri::XML(response.to_str)    done = document.xpath("applications/@current_page").text == document.xpath("applications/@total_pages").text
    document.xpath("//application").each do |item|
      app =
      app["created_at"] = DateTime.parse(item.xpath("created_at").text)
      app["plan_name"] = item.xpath("plan/name").text
      app["service_id"] = item.xpath("plan/service_id").text
      app["account_id"] = item.xpath("user_account_id").text
      app["id"] = item.xpath("id").text
      res << app
  return res
  • Filter the applications that do not meet the criteria, i.e. the plan must be "evaluation" and they have to be newer than 10 days.
def filter_applications(domain, provider_key, plan_name, num_of_days)
  res = api_call_applications_list(domain, provider_key)
  res.each do |item|
    res.delete(item) if item["plan_name"] != plan_name
    res.delete(item) if item["created_at"] > ( - num_of_days)
  return res
  • Then for each application that meets the criteria, get its usage, meaning how many hits the application has had in the last 10 days.
def api_call_application_usage(domain, provider_key, application_id, metric, from, to, granularity)
  url = "https://#{domain}/stats/applications/#{application_id}/usage.xml?provider_key=#{provider_key}&metric_name=#{metric}&since=#{from}&until=#{to}&granularity=#{granularity}"
  response = RestClient.get url
  raise"Wrong response code (#{response.code}) in request #{url}") if response.code!=200
  document = Nokogiri::XML(response.to_str)
  return document.xpath("//usage/data/values").text.split(",")
  • Finally, you must cross-reference the applications to the accounts because the information of the developers is stored in the account object.
def api_call_account_read(domain, provider_key, account_id)
  url = "https://#{domain}/admin/api/accounts/#{account_id}.xml?provider_key=#{provider_key}"
  response = RestClient.get url
  raise"Wrong response code (#{response.code}) in request #{url}") if response.code!=200
  document = Nokogiri::XML(response.to_str)
  account =
  account["email"] = document.xpath("//users/user/email").text
  account["name"] = document.xpath("//users/user/first_name").text + " " + document.xpath("//users/user/last_name").text
  return account

And that’s pretty much it. Now you only need to put everything together (you can get the full script as a gist) and you’re done. You have a script that gets the information that was not yet available on 3scale’s built-in analytics.

1.5. Conclusions

3scale is very DIY-friendly. We believe that anyone should be able to extend the current capabilities of any service that they’ve contracted. As much as we would like to think that we can cover all the bases, we will always be a bit behind in certain aspects, whether because it’s a super special need or simply because we are busy building other features. Whatever the case, we want to avoid blocking you when something is not possible right away. We give you full access to your data and a complete API toolset to work with it.

If you have scripts that you want to share with us and the rest of 3scale’s users, please send them to us. We would be happy to collect them and publish them.

Chapter 2. Out-of-the-box Analytics

By the end of this tutorial, you will be able to find visual information on an application’s traffic.

Each application using an API has a traffic trace in the 3scale system, which can be viewed from the Admin Portal as well as recovered by an API.

2.1. Step 1: Find the application

You can find the application from Audience > Accounts > Listing or Audience > Applications > Listing, or by searching as described in the finding applications tutorial.

2.2. Step 2: Understand the application display

Once you’ve located the application, you’ll see an overview screen with information about the application as shown in the following image.

Application display

The items labeled in the diagram correspond to the following information:

  1. The name of the application given by the developer.
  2. Meta data captured for the application (learn how to set which data to capture in the advanced section).
  3. The status of the application – is it live or suspended?
  4. The current API identifiers, keys, and certificates that the application has. (This view varies depending on what authentication method was used to integrate the API into 3scale).
  5. A summary of traffic statistics for the application.
  6. Information on which application plan the application is on and which rate limits apply.

2.3. Step 3: Use the menu to access the full screen statistics view

To get to the Analytics page of an application, go to the application and click on Analytics in the links located above the application’s name. This will take you to the usage charts view for the application as shown in the image below.

Analytics - Time range

Controlling the metrics, methods, and time range allows you to check different types of data about the application.

Chapter 3. Response Code Tracking

This tutorial shows how to set up and use the response codes log in the 3scale system.

Tracking response codes from your API is a great way to see how your clients are using it and to see in real time whether everything is fine with your servers.

To enable response code tracking feature, set the APICAST_RESPONSE_CODES environment variable to 1 or true when starting APIcast gateway using Docker or OpenShift deployment.

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:{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.

To verify the integration, you must call your API 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. Simply click on the time selection bar and define the time period and granularity that will fit your needs.
