#flume应用参数监控

启动时加上JSON repoting参数,这样就可以通过:34545/metrics访问

flume-ng agent -c . -f exec.conf -n a1 -Dflume.root.logger=INFO,console -Dflume.monitoring.type=http -Dflume.monitoring.port=34545

#生成一些数据

for i in {1..100};do echo "exec test$i" >> /usr/logs/log.10;echo $i;done

#通过shell脚本对JSON输出进行排版

[root@cc-staging-loginmgr2 conf]# curl :34545/metrics 2>/dev/null|sed -e 's/\([,]\)\s*/\1\n/g' -e 's/[{}]/\n/g' -e 's/[",]//g'
