Flume监控指标项

配置监控

1、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"

2、使用以下启动命令

flume-ng agent 
-n a1 
-c $FLUME_HOME/conf 
-f $FLUME_HOME/conf/exec-memory-hdfs-partition.conf 
-Dflume.root.logger=INFO,console 
-Dflume.monitoring.type=http 
-Dflume.monitoring.port=1234
