Please note that for this tutorial I am using APIM 1.10.0 and DAS 3.0.1 versions.
WSO2 API Manager is a complete solution for designing and publishing APIs, creating and managing a developer community, and for securing and routing API traffic in a scalable way. It leverages proven components from the WSO2 platform to secure, integrate and manage APIs. In addition, it integrates with the WSO2 Analytics Platform, and provides out of the box reports and alerts, giving you instant insight into APIs' behavior.

WSO2 Data Analytics Server is a comprehensive enterprise data analytics platform; it fuses batch and real-time analytics of any source of data with predictive analytics via machine learning. It supports the demands of not just business, but Internet of Things solutions, mobile and Web apps.

Configuring WSO2 APIM
===================
1. Navigate to [APIM_HOME]/repository/conf/api-manager.xml and enable the below section.
<!-- For APIM implemented Statistic client for RDBMS -->
<StatisticClientProvider>org.wso2.carbon.apimgt.usage.client.impl.APIUsageStatisticsRdbmsClientImpl</StatisticClientProvider>
2. Start APIM server.
3. Login to dash-board. eg: https://localhost:9443/admin-dashboard. Select "Configure Analytics" & select enable checkbox. Configure as shown below.
Configuring WSO2 DAS
==================
1. In-order to prevent server startup conflicts we will start DAS with port offset value of 1.
To do so navigate to [DAS_HOME]/repository/conf and open carbon.xml file.
<Offset>1</Offset>
2. Navigate to [DAS_HOME]/repository/conf/datasources/master-datasources.xml and add the below.
<datasource>
<name>WSO2AM_STATS_DB</name>
<description>The datasource used for setting statistics to API Manager</description>
<jndiConfig>
<name>jdbc/WSO2AM_STATS_DB</name>
</jndiConfig>
<definition type="RDBMS">
<configuration>
<url>jdbc:mysql://localhost:3306/TestStatsDB?autoReconnect=true&relaxAutoCommit=true</url>
<username>admin</username>
<password>admin</password>
<driverClassName>com.mysql.jdbc.Driver</driverClassName>
<maxActive>50</maxActive>
<maxWait>60000</maxWait>
<testOnBorrow>true</testOnBorrow>
<validationQuery>SELECT 1</validationQuery>
<validationInterval>30000</validationInterval>
</configuration>
</definition>
</datasource>
** IMPORTANT
--------------------
Prio-adding this config you need to create a DB called 'TestStatsDB' in your mysql database & and create required tables. To do so follow below instructions.
[1] Navigate to [APIM_HOME]/dbscripts/stat/sql from your ubuntu console and select mysql.sql script.
type : source [APIM_HOME]/dbscripts/stat/sql/mysql.sql
- Which will create the required tables for our scenario.
[2] Now navigate to [APIM_HOME]/repository/components/lib and add the required mysql connector jar from here.
Create / Publish / Invoke API
======================
1. Navigate to APIM Publisher and create an API. Publish it.
2. Navigate to APIM Store and subscribe to the API.
3. In the Publisher instance select created API and navigate to 'Implement' section and select
Destination-Based Usage Tracking: enable

4. Invoke the API several times.
View API Statistics
==============
Navigate to APIM publisher instance. Select "Statistics" section. Enjoy !!!

If you wanna do a load test scenario or just to play with Jmeter for your easy reference I have attached herewith a sample Jmeter script for 'Calculator API'.
