使用zabbix监控Flume
Flume本身提供了http, ganglia的监控服务，而我们目前主要使用zabbix做监控。因此，我们为Flume添加了zabbix监控模块，和sa的监控服务无缝融合。另一方面，净化Flume的metrics。只将我们需要的metrics发送给zabbix，避免 zabbix server造成压力。目前我们最为关心的是Flume能否及时把应用端发送过来的日志写到Hdfs上， 对应关注的metrics为：[*]Source : 接收的event数和处理的event数
[*]Channel : Channel中拥堵的event数
[*]Sink : 已经处理的event数

#flume应用参数监控
启动时加上JSON repoting参数,这样就可以通过http://localhost:34545/metrics访问
bin/flume-ng agent -n consumer -c conf -f bin/conf.properties -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
curl http://localhost:34545/metrics 2>/dev/null|sed -e's/\([,]\)\s*/\1\n/g' -e 's/[{}]/\n/g' -e 's/[",]//g'
