序
statsd-jvm-profiler是etsy开发的一个 JVM 代理 Profiler,其将Profile数据发送到 StatsD.
-javaagent加载
-javaagent:/usr/etsy/statsd-jvm-profiler/statsd-jvm-profiler.jar=server=statsdHost,port=statsdPort
运行时动态加载
将该jar包拷贝到spring boot工程的main resource目录下,然后
@Bean
public CommandLineRunner loadProfilerAgent(){
return new CommandLineRunner() {
@Override
public void run(String... strings) throws Exception {
ApplicationPid pid = new ApplicationPid();
try{
com.sun.tools.attach.VirtualMachine vm = com.sun.tools.attach.VirtualMachine.attach(pid.toString());
ClassLoader classLoader = getClass().getClassLoader();
String profilerJarPath = classLoader.getResource("statsd-jvm-profiler-2.0.0.jar").getPath();
String agentArgs = "server="+statsdHost+",port="+statsdPort;
vm.loadAgent(profilerJarPath, agentArgs);
vm.detach();
System.out.println("Dynamically loaded StatsD JVM Profiler Agent...");
}catch (Exception e){
e.printStackTrace();
}
}
};
}
内置httpServer
该agent内置了一个http server,默认端口为5005,可以访问如下几个path
http://localhost:5005/errors
http://localhost:5005/isRunning
http://localhost:5005/profilers
http://localhost:5005/disable/:profiler
http://localhost:5005/status/profiler/:profiler
graphite
在graphite里头,statsd-jvm-profiler前缀的gauges就是了。
