BTrace 进行性能测试

使用BTrace 做性能测试在官网https://kenai.com/projects/btrace/downloads/directory/releases/release-1.2.4下载对应的jar包测试时后，将btrace测试类和被测试类放在同一个机器上将btrace测试类写好，放在btrace解压的bin目录下调用如下命令进行测试sh btrace pid BtraceTest.javapid可通过jps命令来查看，默认端口是2020端口，如果被测试类有多个进程，则端口号累加2021 2022 2023 ……Btrace类import com.sun.btrace.annotations.BTrace;import com.sun.btrace.annotations.Kind;import com.sun.btrace.annotations.Location;import com.sun.btrace.annotations.OnMethod;import com.sun.btrace.annotations.ProbeClassName;import com.sun.btrace.annotations.ProbeMethodName;import com.sun.btrace.annotations.TLS; import static com.sun.btrace.BTraceUtils.*; @BTracepublic class BtraceTest { @TLS private static long startTime=0; @OnMethod（clazz = "/*/", method = "/.*/", location = @Location（value=Kind.ENTRY, clazz="/.*/", method="/.*/"）） public static void startMethod（） { startTime =timeMillis（）; } @OnMethod（clazz = "/*/", method = "/.*/", location = @Location（value=Kind.RETURN, clazz="/.*/", method="/.*/"）） public static void endMethod（@ProbeClassName String className, @ProbeMethodName String methodName） { println（concat（"threadId:", str（threadId（currentThread（）））））; println（strcat（"className:", className））; println（strcat（"methodName:", methodName））; println（strcat（"exeTime:", str（timeMillis（）-startTime）））; } @OnMethod（clazz = "//", method = "sendHttpRequest", location = @Location（value=Kind.RETURN, clazz="/.*/", method="/.*/"）） public static void endMethod2（@ProbeClassName String className, @ProbeMethodName String methodName） { println（"CommonBizImpl----sendHttpRequest----------"）; //System.out.println（"CommonBizImpl----sendHttpRequest----------"）; println（concat（"threadId:", str（threadId（currentThread（）））））; println（strcat（"className:", className））; println（strcat（"methodName:", methodName））; println（strcat（"exeTime:", str（timeMillis（）-startTime）））; } }
