Apache Stratos Data Analytics Server (DAS) extensions include DAS artifacts and stratos-das-extension jar which has spark UDF (User Defined Funtion) used in spark script. You can configure an external DAS for stratos metering and monitoring feature as below:

Follow the below steps to configure DAS for metering dashboard:

  1. Add org.apache.stratos.das.extension-.jar file to /repository/components/lib/.

  2. Add UDF class <class-name>org.apache.stratos.das.extension.TimeUDF</class-name> to ‘spark-udf-config.xml’ file in <DAS-HOME>/repository/conf/analytics/spark/ folder.

  3. Add jaggery files needed for your database type which can be found in <Stratos-DAS-Distribution>/metering-dashboard/jaggery-files/<db>/ to DAS server path <DAS_HOME/repository/deployment/server/jaggeryapps/portal/controllers/apis/.

  4. Create MySQL/Oracle database and tables using queries in <Stratos-DAS-Distribution>/metering-dashboard/database-scripts/<db>/metering-script.sql manually.

  5. Apply ues-patch files in <Stratos-DAS-Distribution>/metering-dashboard/ues-patch/ to DAS below:

    • Copy ‘ues-gadgets.js’ and ‘ues-pubsub.js’ files to <DAS-HOME>/repository/deployment/server/jaggeryapps/portal/js/ folder.
    • Copy ‘dashboard.jag’ file to <DAS-HOME>/repository/deployment/server/jaggeryapps/portal/theme/templates/ folder.

  6. Add stratos-metering-service car file in <Stratos-DAS-Distribution>/metering-dashboard/ to <DAS-HOME>/repository/deployment/server/carbonapps/ to generate the metering dashboard.

Follow the below steps to configure DAS for monitoring dashboard:

  1. Add jaggery files needed for your database type which can be found in <Stratos-DAS-Distribution>/monitoring-dashboard/jaggery-files/<db>/ to DAS path `<DAS_HOME/repository/deployment/server/jaggeryapps/portal/controllers/apis/.

  2. Create MySQL/Oracle database and tables using queries in <Stratos-DAS-Distribution>/monitoring-dashboard/database-scripts/<db>/monitoring-script.sql manually.

  3. Copy CEP EventFormatter artifacts in <Stratos-DAS-Distribution>/wso2cep-<version>/eventformatters/ to <CEP-HOME>/repository/deployment/server/eventformatters/.

  4. Copy CEP OutputEventAdapter artifact in <Stratos-DAS-Distribution>/wso2cep-<version>/outputeventadaptors/ to <CEP-HOME>/repository/deployment/server/outputeventadaptors/ and update the tcp and ssl ports according to DAS server port offset.

  5. Add stratos-monitoring-service car file in <Stratos-DAS-Distribution>/monitoring-dashboard/ to <DAS-HOME>/repository/deployment/server/carbonapps/ to generate the monitoring dashboard.
