Issue/Introduction

 This document describes creating a dummy application to simulate a backend metric.

Environment

Any Introscope Java Agent.

Resolution

 1. Create a HelloWorld Dummy application:

import java.util.*;

import java.text.*;

public class ProbedHelloWorld {   

    SimpleDateFormat sdf_ = new SimpleDateFormat();

    Date date_ = new Date();   

    public ProbedHelloWorld() throws Exception {

        Thread.sleep(1000);       

        Properties prop = System.getProperties();

        prop.list(System.out);               

        while (true) {

            callA(1000);

        }

    }  

    public void callA(long time) throws Exception {

        date_.setTime(System.currentTimeMillis());       

        System.out.println(sdf_.format(date_) + " Still running...");       

        Thread.sleep(time);

    }

 

    public static void main(String args[]) throws Exception {

        new ProbedHelloWorld();

    }

}

 

 2. Create a custom PBD: HW.pbd

TurnOn: MyCustomTracerGroup

SetFlag: MyCustomTracerGroup

IdentifyClassAs: ProbedHelloWorld MyCustomTracerGroup

IdentifyInheritedAs: ProbedHellowWorld MyCustomTracerGroup

TraceOneMethodOfClass: ProbedHelloWorld callA BackendMarker "{classname}|{method}"

 

 3. Add HW.pbd to the IntroscopeAgent.profile:

introscope.autoprobe.directivesFile=default-typical-legacy.pbl,hotdeploy,HW.pbd

4. Restart the JVM to instrument the backend metric.

5. See the result in the Investigator:
