Open the <APIM_HOME>/repository/conf/api-manager.xml file.
Carry out the following configuration changes under the <APIUsageTracking> element in the XML file.
1. Enable Analytics in APIM by uncommenting and setting the <Enabled> element to true.
  Code Block
  <Enabled>true</Enabled>
2. Define the <DASServerURL> value based on the WSO2 Data Analytics Server (WSO2 DAS) receivers.
  Code Block
  title Example
  <DASServerURL> {tcp://localhost:7612/,tcp://localhost:7613/} </DASServerURL>
3. Define the <DASUsername> and <DASPassword> based on the DAS receivers.
4. Define the <DASRestApiURL> element according to the DAS master node, because this URL is used to fetch data from DAS REST API.
5. Set the <DASRestApiUsername> and <DASRestApiPassword> element according to the DAS REST API.
Use the default configurations for the other configurations in the <APIUsageTracking> section.
Configure the statistics client.
Set the RDBMS client using the <StatisticClientProvider> element in the <APIM_HOME>/repository/conf/api-manager
.
xml file as follows:By default APIM is configured for the DAS REST client. Therefore, disable the REST client by commenting out the following:
Code Block

Set the RDBMS client by uncommenting the following:

Tip
The RDBMS client is the recommended option when using Analytics with APIM in production.

Code Block
<!-- For APIM implemented Statistic client for RDBMS --> <StatisticClientProvider>org.wso2.carbon.apimgt.usage.client.impl.APIUsageStatisticsRdbmsClientImpl</StatisticClientProvider>

Define a datasource for the RDBMS client.
Do this by adding the following configuration in both the <APIM_HOME>/repository/conf/datasources/master-datasources.xml and <DAS_HOME>/repository/conf/datasources/master-datasources.xml files.

Code Block

<datasource> <name>WSO2AM_STATS_DB</name> <description>The datasource used for registry and user manager</description> <jndiConfig> <name>jdbc/WSO2AM_STATS_DB</name> </jndiConfig> <definition type="RDBMS">

<configuration> <url>jdbc:mysql://localhost:3306/APIM_STAT?autoReconnect=true&</url> <username>root</username> <password>pass</password> <driverClassName>com.mysql.jdbc.Driver</driverClassName> <maxActive>50</maxActive> <maxWait>60000</maxWait> <testOnBorrow>true</testOnBorrow> <validationQuery>SELECT 1</validationQuery> <validationInterval>30000</validationInterval> <defaultAutoCommit>false</defaultAutoCommit> </configuration> </definition> </datasource>

Copy the appropriate RDBMS driver into both the WSO2 DAS and WSO2 APIM /repository/components/lib directories.

Deploy CApp.
As the summarization logic is defined in the DAS CApp, you need to depoy it in all the DAS nodes. When configuring Analytics using XML, you need to deploy the CApp manually.

Info
If you were to configure Analytics via the UI the CApp deployment process takes place automatically. The APIM Analytics related CApps are found in the `<APIM_HOME>/statistics` directory. Use the `API_Manager_Analytics_RDBMS.car` for RDBMS configurations and the `API_Manager_Analytics_REST.car` for the REST client.

Use one of the following methods to deploy the CApp into DAS.

Copy the <APIM_HOME>/statistics/API_Manager_Analytics_RDBMS.car file into the <DAS_HOME>/repository/deployment/server/carbonapps directory. If the /carbonapps directory does not exist create the directory. Thereafter, restart WSO2 DAS.

Start WSO2 DAS and sign in to the DAS Management Console. Navigate to the main menu and click Carbon Applications. Click Add and deploy the CApp which is in the <APIM_HOME>/statistics directory.

    REST client <APIM_HOME>/statistics/API_Manager_Analytics_REST.car
    Tip
    If the /carbonapps directory does not exist create the directory.
  2. Restart WSO2 DAS.
2. Deploy the CApp via the UI
  1. Start WSO2 DAS and sign in to the DAS Management Console.
  2. Navigate to the main menu and click Carbon Applications.
  3. Click Add and deploy the CApp which is in the <APIM_HOME>/statistics directory.
