Zabbix通过Agent模式监控Zookeeper中间件

四字命令详解：

方式一：

zookeeper中间件服务状态：echo ruok |nc |localhost 2181

imok

zookeeper中间件服务性能：echo mntr |nc |localhost 2181

方式二：

zookeeper中间件服务状态：(echo ruok;sleep 2) |telnet localhost $zk_port 2>/dev/null |sed -n '4p'

imok

zookeeper中间件服务性能：(echo mntr;sleep 2) |telnet localhost $zk_port 2>/dev/null |  grep $zk_mntr |awk '{print $2}'

脚本逻辑：

1.zookeeper中间件服务状态

zk_port=$1

ruok=`(echo ruok;sleep 2) |telnet localhost $zk_port 2>/dev/null |  sed -n '4p'`

 if [ -n "$ruok" ];then

echo $ruok

echo "`date +%y%m%d-%H:%M:%S`$zk_ruok:$ruok" >> $logfile

else

echo NO

echo "`date +%y%m%d-%H:%M:%S`$zk_ruok:NO" >> $logfile

fi

2.zookeeper中间件服务性能

zk_port=$1

mntr=`(echo mntr;sleep 2) |telnet localhost $zk_port 2>/dev/null |  grep $zk_mntr |awk '{print $2}'`

 if [ -n "$mntr" ];then

echo $mntr

echo "`date +%y%m%d-%H:%M:%S`$zk_mntr:$mntr" >> $logfile

else

echo 0

echo "`date +%y%m%d-%H:%M:%S`$zk_ruok:0" >> $logfile

fi
