WSO2 API Manager can be configured to track runtime statistics of API invocations through Google Analytics (http://www.google.com/analytics). Google Analytics is a service which allows you to track visits to a website and generate detailed statistics.
This guide explains how to setup API Manager in order to feed runtime statistics for summarization and display to Google analytics.
1. Setup a Google Analytics account if not subscribed already and receive a Tracking ID, which is of the format "UA-XXXXXXXX-X". A Tracking ID is issued at the time an account is created with Google Analytics.
2. Open $AM_HOME/repository/conf/api-manager.xml. Enable the <GoogleAnalyticsTracking> element and enter the Tracking-ID.
<GoogleAnalyticsTracking> <!-- Enable/Disable Google Analytics Tracking --> <Enabled>false</Enabled> <!-- Google Analytics Tracking ID --> <TrackingID>UA-XXXXXXXX-X</TrackingID> </GoogleAnalyticsTracking>
3. Save the file and restart the API Manager instance.
4. API Manager is now integrated with Google Analytics. A user who has subscribed to a published API through the API Store should see an icon as "Real-Time" after logging into their Google Analytics account. Click on this icon and select "Overview".
5. Then invoke the above API through the embedded WSO2 REST Client (or any third-part rest client such as cURL).
Real-Time Statistics
6. This is an invocation of the API. Accordingly, Google Analytics graphs and statistics will be displayed on runtime. In this case it will be a hit on 'PageViews' Per second graph and also 1 user active as shown in the screenshot below.
Reporting Statistics
Google Analytics reporting statistics population takes more than 24 hours from the time of invocation. Shown below is a sample Dashboard with populated statistics.
