Web application test monitoring execution time--Javasimon

The overall performance of using the Jmeter-plugins and VISUALVM monitoring systems was previously described in system performance tuning, and sometimes it is necessary to know how long some specific method calls are consuming to find bottlenecks. VISUALVM can do it, but it's too resource-intensive if you do profiler. Personally feel that Javasimon is a very good choice. Not only can easily monitor the data layer, business layer, the Web layer of the respective access time, but also provides a Web page view statistics and system alarm notification function, very good.
Describe how Javasimon is used in spring-based web systems.

1. Web page statistics, Web pages view and how to notify alerts

2. Spring configuration file

Note that this is only valid for the bean defined in the Spring configuration file (the controller in SPRING-MVC is not valid)

       <bean id= "monitoringinterceptor" class=" Org.javasimon.spring.MonitoringInterceptor "/>        <aop:config>                <!--name of the class or interface --                <aop:pointcut id="Monitoringpointcut" expression="Execution (* com.cloud.service.serviceimpl.* (..)) " />                <aop:advisor advice-ref= "monitoringinterceptor" pointcut-ref=" Monitoringpointcut "/>        </aop:config>

3. JDBC Layer

Use Simon's JDBC driver instead of the official driver, or package DataSource to achieve the goal.

You can view different layer access times in your Web app to locate system bottlenecks.
