Enable API tracking option by setting the <APIUsageTracking> element to true in <APIM_HOME>/repository/conf/api-manager.xml. Also specify the data source used for getting BAM statistics in <DataSourceName> element. For example,

Code Block

language	html/xml

<APIUsageTracking>

    <!-- Enable/Disable the API usage tracker. -->
    <Enabled>true</Enabled>   
    <PublisherClass>org.wso2.carbon.apimgt.usage.publisher.APIMgtUsageDataBridgeDataPublisher</PublisherClass>
    <ThriftPort>7612</ThriftPort> 
    <BAMServerURL>tcp://localhost:7612/</BAMServerURL>
    <BAMUsername>admin</BAMUsername>
    <BAMPassword>admin</BAMPassword>
    <!-- JNDI name of the data source to be used for getting BAM statistics. This data source should
        be defined in the master-datasources.xml file in conf/datasources directory. -->
    <DataSourceName>jdbc/WSO2AM_STATS_DB</DataSourceName>

</APIUsageTracking>

Note
In the above configuration, the default Thrift port is increased by 1 because we apply an offset of 1 to default BAM port later in this guide.

Specify the data source definition in <APIM_HOME>/repository/conf/datasources/master-datasources.xml file as follows. WSO2AM_STATS_DB is the datasource used to fetch analytical data.

Code Block

language	html/xml

  <datasource>
          <name>WSO2AM_STATS_DB</name>
          <description>The datasource used for getting statistics to API Manager</description>
        <jndiConfig>
                <name>jdbc/WSO2AM_STATS_DB</name>
            </jndiConfig>
          <definition type="RDBMS">
          <configuration>
                 <!-- JDBC URL to query the database -->
                 <url>jdbc:h2:<BAM_HOME>/repository/database/APIMGTSTATS_DB;AUTO_SERVER=TRUE</url>
                 <username>wso2carbon</username>
                 <password>wso2carbon</password>
                 <driverClassName>org.h2.Driver</driverClassName>
                 <maxActive>50</maxActive>
                 <maxWait>60000</maxWait>
                 <testOnBorrow>true</testOnBorrow>
                 <validationQuery>SELECT 1</validationQuery>
                 <validationInterval>30000</validationInterval>
            </configuration>
         </definition>
  </datasource>

Note

In the above configuration,

Replace <BAM_HOME> with the absolute path of BAM installation directory.
The JNDI config name must match with configurations of api-manager.xml file defined later in this guide.

Next, prepare BAM to collect and analyze statistics from API manager.
