2、执行以下命令
unzip profiler-server-linuxamd64.zip -d remote 修改 remote/bin/calibrate-16.sh JAVA_HOME=/opt/java/jdk1.6.0_43 export JAVA_HOME hadoop@m1hadoop:~/remote/bin$ ./calibrate-16.sh Profiler Agent: JNI OnLoad Initializing... Profiler Agent: JNI OnLoad Initialized successfully Starting calibration... Calibration performed successfully For your reference, obtained results are as follows: Approximate time in one methodEntry()/methodExit() call pair: When getting absolute timestamp only: 0.1112 microseconds When getting thread CPU timestamp only: 11.5599 microseconds When getting both timestamps: 11.6962 microseconds Approximate time in one methodEntry()/methodExit() call pair in sampled instrumentation mode: 0.0475 microseconds 修改profile-16.sh JAVA_HOME=/opt/java/jdk1.6.0_43 export JAVA_HOME hadoop@m1hadoop:~/remote/bin$ ./profile-16.sh Profiler Agent: Initializing...

步骤 4: 将以下参数添加到应用程序启动脚本 (复制到剪贴板):
-XX:+UseLinuxPosixThreadCPUClocks -agentpath:/home/hadoop/remote/lib/deployed/jdk16/linux-amd64/libprofilerinterface.so=/home/hadoop/remote/lib,5140
JAVA_OPTS="-Xmx20m -XX:+UseLinuxPosixThreadCPUClocks -agentpath:/home/hadoop/remote/lib/deployed/jdk16/linux-amd64/libprofilerinterface.so=/home/hadoop/remote/lib,5140"
bin/flume-ng agent -c conf -f conf/flume-conf.properties.template
hadoop@m1hadoop:~/apache-flume-1.5.0.1-bin$ nohup bin/flume-ng agent -c conf -f conf/flume-conf.properties.template -n a1 &
hosts 配置别忘了
