cat-boot-profiling

Profiling

Simple built-in profiling without any extra tools

Integration

With Gradle

runtime('cc.catalysts.boot:cat-boot-profiling:' + catBootVersion)

Configuration

This module comes with an AutoConfiguration.

Usage

Use the annotation @MethodProfling on any Spring Bean to log method calls. Nested calls to multiple beans that have that annotation are accumulated. As an example, if you have those two beans:

@MethodProfiling
@Component
public class SimpleBean {

    @Autowired
    NestedBean nestedBean;

    public String callMe() {
        return nestedBean.callMeAgain();
    }
}

@MethodProfiling
@Component
public class NestedBean {

    public String callSubMethod() {
        return "Test";
    }
}

And you then perform a call to simpleBean.callMe(), then you might run into log output like this:

[2016-04-30 12:53:52.524] TRACE [main] --- c.c.b.p.SimpleBean: 
----------------------------------------------------------------------------------
   calls     avg ms   total ms      %   Signature
----------------------------------------------------------------------------------
       1      59,00         59  98,33   SimpleBean.callMe()
       1      29,00         29  48,33     NestedBean.callSubMethod()

Don't forget to set the log level of your target bean (the bean that holds the annotation) to TRACE.
