Customizing Statistics Publishing
The following needs to be done in order to implement a custom statistics observer.
To disable operation of publishing statistics via the EI Analytics server, add the following configuration in theÂ
<EI_HOME>/conf/carbon.xml
file totrue
as shown below.<MediationFlowStatisticConfig> <AnalyticPublishingDisable>true</AnalyticPublishingDisable> </MediationFlowStatisticConfig>
This is useful when you want to collect statistics using a product other than EI Analytics. In such scenarios, preventing the EI Analytics server from publishing statistics allows you to avoid incurring an unnecessary system overhead.
Â- Create the JAR file with the that contains the required statistics observer implementation, and copy it to theÂ
<EI_HOME>/lib
directory. This implementation should have the following.- The
org.wso2.carbon.das.messageflow.data.publisher.observer.MessageFlowObserver
 interface. - If the observer is tenant aware, it should also implementÂ
org.wso2.carbon.das.messageflow.data.publisher.observer.TenantInformation
.

Add all the observers as a comma separated list in theÂ
<EI_HOME>/conf/carbon.xml
 file as shown in the example below.<MediationFlowStatisticConfig> <Observers> org.wso2.custom.Observer1,org.wso2.custom.Observer2 </Observers> </MediationFlowStatisticConfig>
