配置监控
修改flume.env.sh
export JAVA_OPTS=”-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=5445 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false”使用以下脚本
flume-ng agent \ --name a1 \ --conf $FLUME_HOME/conf \ --conf-file $FLUME_HOME/conf/exec-memory-hdfs-partition.conf \ -Dflume.root.logger=INFO,console \ -Dflume.monitoring.type=http \ -Dflume.monitoring.port=1234
