Class HystrixRequestLogViaLoggerServletFilter

java.lang.Object

com.netflix.hystrix.contrib.requestservlet.HystrixRequestLogViaLoggerServletFilter

All Implemented Interfaces:

javax.servlet.Filter

public class HystrixRequestLogViaLoggerServletFilter
extends java.lang.Object
implements javax.servlet.Filter

Log an INFO message with the output from HystrixRequestLog.getCurrentRequest().getExecutedCommandsAsString() at the end of each requet.

A pre-requisite is that HystrixRequestContext is initialized, such as by using HystrixRequestContextServletFilter.

Install by adding the following lines to your project web.xml:

 <filter>
     <display-name>HystrixRequestLogViaLoggerServletFilter</display-name>
     <filter-name>HystrixRequestLogViaLoggerServletFilter</filter-name>
     <filter-class>com.netflix.hystrix.contrib.requestservlet.HystrixRequestLogViaLoggerServletFilter</filter-class>
   </filter>
   <filter-mapping>
     <filter-name>HystrixRequestLogViaLoggerServletFilter</filter-name>
     <url-pattern>/*</url-pattern>
   </filter-mapping>
 
 

NOTE: This filter must complete before HystrixRequestContext is shutdown otherwise the HystrixRequestLog will already be cleared.

This will output a log line similar to this:

 Hystrix Executions [POST /order] => CreditCardCommand[SUCCESS][1122ms]
