The advantage of having per-service log files is that it is very easy to analyze/monitor what went wrong in this particular service (proxy service, data service etc.) by looking at the service log. This the basic logs relevant to a proxy service defined in the ESB. This file will contain the complete log with every log statement, including the service logs the service logs that you have configured to be logged into a different log file. In other words, the service log is an additional log file, which will contain a copy of the logs to that particular service.

  1. See Sample 150 in Proxy Service Samples. It has a proxy service named StockQuoteProxy.
  2. Configure log4j to log the service specific logs to a file called stock-quote-proxy-service.log in the logs directory of the EI installation directory.
    1. Open up the log4j.properties file found in the conf directory of the WSO2 EI installation directory using your favorite text editor and add the following section to the end of the file starting in a new line.

      Code Block
      log4j.category.SERVICE_LOGGER.StockQuoteProxy=DEBUG, SQ_PROXY_APPENDER
      log4j.additivity.SERVICE_LOGGER.StockQuoteProxy=false
      log4j.appender.SQ_PROXY_APPENDER=org.apache.log4j.DailyRollingFileAppender
      log4j.appender.SQ_PROXY_APPENDER.File=logs/stock-quote-proxy-service.log
      log4j.appender.SQ_PROXY_APPENDER.datePattern='.'yyyy-MM-dd-HH-mm
      log4j.appender.SQ_PROXY_APPENDER.layout=org.apache.log4j.PatternLayout
      log4j.appender.SQ_PROXY_APPENDER.layout.ConversionPattern=%d{ISO8601} \[%X{ip}-%X{host}\] \[%t\] %5p %c{1} %m%n
    2. Save the file.
  3. Execute the sample client after starting the server with sample 150: and the sample axis2 server with the SimpleStockQuote service deployed on it as per stated in the sample documentation.
