Configuring Analytics for Choreo Connect

Choreo Connect is capable of publishing fine grained analytics events which can then be used to generate reports, dashboards, statistics, and graphs for the APIs deployed on Choreo Connect. Choreo Connect can not only publish analytics data to the Choreo platform but also to platforms that support the ELK stack. The following subsections will explain in detail how you could enable and configure analytics for each platform to gain insights into the services exposed via Choreo Connect.

Tip

To learn more on the analytics-related concepts, see Choreo Connect Analytics - Concepts.

Configure Analytics for Choreo Connect using one of the following methods:

• Choreo Portal Analytics for Choreo Connect
• ELK Analytics for Choreo Connect

Configuring Choreo Portal Analytics

Configuring ELK Analytics

Follow the instructions below to configure ELK Analytics for Choreo Connect

The Enforcer component in Choreo Connect can log analytics-related data to be used by Filebeat in ELK Stack. Data flow for the ELK Analytics can be depicted as given above.

Step 1 - Configure Choreo Connect

Step 1.1 - Compile the reporter implementation

Follow the instructions below to compile the reporter implementation as a JAR file:

1. Checkout and build the wso2/samples-apim repository.

2. Navigate to the analytics-event-publisher/target directory.

3. Copy and paste the generated JAR in to the choreo-connect-1.x.x/docker-compose/resources/enforcer/dropins directory.

   This JAR will be mounted into the /home/wso2/lib/dropins directory within the Enforcer when the Enforcer starts.

Step 1.2 - Configure the config.toml file

1. Open the Choreo Connect configuration file according to the deployment type you are using.

   Click here to see the configuration file location for your Choreo Connect deployment.

   Navigate to the correct folder path and open the config.toml or config-toml-configmap.yaml file based on your Choreo Connect deployment.

   Deployment	Mode	File name	Directory
   Docker Compose	Choreo Connect as a Standalone Gateway	config.toml	<CHOREO-CONNECT_HOME>/docker-compose/choreo-connect/conf/
   Docker Compose	Choreo Connect with WSO2 API Manager as a Control Plane	config.toml	<CHOREO-CONNECT_HOME>/docker-compose/choreo-connect-with-apim/conf/
   Kubernetes	Choreo Connect as a Standalone Gateway	config-toml-configmap.yaml	<CHOREO-CONNECT_HOME>/k8s-artifacts/choreo-connect/
   Kubernetes	Choreo Connect with WSO2 API Manager as a Control Plane	config-toml-configmap.yaml	<CHOREO-CONNECT_HOME>/k8s-artifacts/choreo-connect-with-apim/

2. Change the analytics section based on the following configurations.

   [analytics]
       enabled = true
   
   [analytics.enforcer]
       [analytics.enforcer.configProperties]
           "publisher.reporter.class" = "org.wso2.am.analytics.publisher.sample.reporter.CustomReporter"

If you want to use a custom reporter class

Set the value of the publisher.reporter.class property to the class name of the new reporter implementation in the config.toml file.

Step 1.3 - Enable logs

The following are the two options that are available to retrieve the analytics logs.

• Log to console
• Log to file

Update the choreo-connect-1.x.x/docker-compose/choreo-connect(-with-apim)/conf/log4j2.properties file based on the selected analytics logs retrieval method as follows in order to configure the Filebeat agent.

Log to console

1. Add a reporter to the loggers list.

   loggers = reporter, ... (list of other available loggers)

2. Add the following configurations after the loggers.

   logger.reporter.name = org.wso2.am.analytics.publisher.sample.reporter
   logger.reporter.level = INFO
   logger.reporter.additivity = false
   logger.reporter.appenderRef.rolling.ref = ENFORCER_CONSOLE

Log to file

1. Add ENFORCER_ANALYTICS to the appenders list.

   appenders = ENFORCER_ANALYTICS, ... (list of other available appenders)

2. Add the following configuration after the appenders.

   appender.ENFORCER_ANALYTICS.type = RollingFile
   appender.ENFORCER_ANALYTICS.name = ENFORCER_ANALYTICS
   appender.ENFORCER_ANALYTICS.fileName = logs/enforcer_analytics.log
   appender.ENFORCER_ANALYTICS.filePattern = /logs/enforcer_analytics-%d{MM-dd-yyyy}.log
   appender.ENFORCER_ANALYTICS.layout.type = PatternLayout
   appender.ENFORCER_ANALYTICS.layout.pattern = [%d] - %m%ex%n
   appender.ENFORCER_ANALYTICS.policies.type = Policies
   appender.ENFORCER_ANALYTICS.policies.time.type = TimeBasedTriggeringPolicy
   appender.ENFORCER_ANALYTICS.policies.time.interval = 1
   appender.ENFORCER_ANALYTICS.policies.time.modulate = true
   appender.ENFORCER_ANALYTICS.policies.size.type = SizeBasedTriggeringPolicy
   appender.ENFORCER_ANALYTICS.policies.size.size=10MB
   appender.ENFORCER_ANALYTICS.strategy.type = DefaultRolloverStrategy
   appender.ENFORCER_ANALYTICS.strategy.max = 20
   appender.ENFORCER_ANALYTICS.filter.threshold.type = ThresholdFilter
   appender.ENFORCER_ANALYTICS.filter.threshold.level = DEBUG

3. Add a reporter to the loggers list.

   loggers = reporter, ... (list of other available loggers)

4. Add the following configurations after the loggers.

   logger.reporter.name = org.wso2.am.analytics.publisher.sample.reporter
   logger.reporter.level = INFO
   logger.reporter.additivity = false
   logger.reporter.appenderRef.rolling.ref = ENFORCER_ANALYTICS

Note

If you use a custom reporter class, update the logger.reporter.name property accordingly.

Step 2 - Set up the ELK Stack

1. Configure and setup the following elements in ELK Stack.

   • Elasticsearch
   • Kibana
   • Logstash
   • Filebeat

2. Configure the log file input source.

   1. Open the filebeat.yml file.

   2. Configure the container log files as the input source.

        filebeat.inputs:
        - type: container
          enabled: true
          paths:
            - /var/lib/docker/containers/*/*.log
          include_lines: ['(apimMetrics):']

Step 3 - Publish an API

Publish an API to the Choreo Connect by either using API Manager or apictl.

Step 4 - Invoke requests

Invoke a few requests (success and failure).

Step 5 - View the dashboards

Check the Kibana dashboard.

You will notice that the populated data appears in different dashboards.
