Question

I followed the Clustering Topology in the Doc: https://docs.wso2.com/display/EI640/Clustering+the+ESB+Profile and the Toplogy was done and the ESB Nodes are running correctly. Suppose that my nodes are n1.ei.com for Node1 and n2.ei.com for Node2 and lb.ei.com for LoadBalancing. I want to start the Analytic Dashboard on Node1, as a service it started running on https://n1.ei.com:9643/portal but i dont get any data or API to monitor. I followed the wso2carbon.log and found the following error:

Error while trying to connect to the endpoint. Cannot borrow client for ssl://${Node1_IP_ADDR}:7712

Noting that my port Offset is 0, on Similar questions I found people referring to api-manager.xml file but i dont have these files. I only have MessageFlowStatisticsPublisher.xml and MessageFlowConfigurationPublisher.xml and I edited them as follows:

<?xml version="1.0" encoding="UTF-8"?>
<eventPublisher name="MessageFlowConfigurationPublisher/StatisticsPublisher"
  statistics="disable" trace="disable" xmlns="http://wso2.org/carbon/eventpublisher">
  <from streamName="org.wso2.esb.analytics.stream.ConfigEntry" version="1.0.0"/>
  <mapping customMapping="disable" type="wso2event"/>
  <to eventAdapterType="wso2event">
    <property name="username">adminuser</property>
    <property encrypted="true" name="password">CIPHERED_TEXT</property>
    <property name="protocol">thrift</property>
    <property name="publishingMode">blocking</property>
    <property name="publishTimeout">0</property>
    <property name="receiverURL">tcp://${Node1_IP_ADDR:7612}</property>
    <property encrypted="true" name="password">CIPHERED_TEXT</property>
  </to>
</eventPublisher>

Where can i Solve the above error considering my Clustered Environment.

Answer 1

编辑/conf/log4j.properties并检查LOGEVENT块中是否有正确的信息：

log4j.appender.LOGEVENT = org.wso2.carbon.logging.service.appender.LogEventAppender   log4j.appender.LOGEVENT.url = tcp：// localhost：7611   log4j.appender.LOGEVENT.layout = org.wso2.carbon.utils.logging.TenantAwarePatternLayout   log4j.appender.LOGEVENT.columnList =％T，％S，％A，％d，％c，％p，％m，％I，％Stacktrace   log4j.appender.LOGEVENT.userName = admin

log4j.appender.LOGEVENT.password = admin

log4j.appender.LOGEVENT.processingLimit = 1000   log4j.appender.LOGEVENT.maxTolerableConsecutiveFailure = 20

Answer 2

感谢您的答复，但我知道了：如您所见，这里有一个名为statistics的值，在上面的问题中已被禁用，因此我对其进行了更改，现在Analytic Dashboard可以读取数据。

<?xml version="1.0" encoding="UTF-8"?>
<eventPublisher name="MessageFlowConfigurationPublisher/StatisticsPublisher"
  statistics="enable" trace="disable" xmlns="http://wso2.org/carbon/eventpublisher">
  <from streamName="org.wso2.esb.analytics.stream.ConfigEntry" version="1.0.0"/>
  <mapping customMapping="disable" type="wso2event"/>
  <to eventAdapterType="wso2event">
    <property name="username">adminuser</property>
    <property encrypted="true" name="password">CIPHERED_TEXT</property>
    <property name="protocol">thrift</property>
    <property name="publishingMode">blocking</property>
    <property name="publishTimeout">0</property>
    <property name="receiverURL">tcp://${Node1_IP_ADDR:7612}</property>
    <property encrypted="true" name="password">CIPHERED_TEXT</property>
  </to>
</eventPublisher>
