Tentei configurar o WSO2 EI Analytics 6.1.1u23 para usar o MongoDb como armazenamento de eventos, mas sem sucesso. eu encontreieste PR adicionar suporte ao MongoDb para registros do Analytics; Eu adicionei no analytics-datasources.xml esta configuração:

<providers>
    <provider>org.wso2.carbon.datasource.reader.mongo.MongoDataSourceReader</provider>
</providers>

<datasource>
           <name>WSO2_ANALYTICS_DS_MONGO</name>
           <description>The datasource used for analytics record store</description>
           <definition type="MONGO">
               <configuration>
                   <host>xxx.xxx.xxx.xxx</host>
                   <port>27017</port>
               </configuration>
           </definition>
</datasource>

E no analytics-config.xml esta configuração:

<analytics-record-store name="EVENT_STORE">
<implementation>org.wso2.carbon.analytics.datasource.mongo.MongoAnalyticsRecordStore</implementation>
       <properties>
           <property name="datasource">WSO2_ANALYTICS_DS_MONGO</property>
           <property name="database">WSO2_DAS_EVENT</property>
       </properties>
 </analytics-record-store>

Na inicialização, recebo o seguinte erro:Não é possível encontrar o org.wso2.carbon.datasource.reader.mongo.MongoDa taSourceReader

ATUALIZAR: Eu adicionei a biblioteca ausenteorg.wso2.carbon.datasource.reader.mongo-4.4.33.jar e agora recebo o seguinte erro:
