zookeeper监控要点
zk_avg/min/max_latency 响应一个客户端请求的时间，建议这个时间大于10个Tick就报警
zk_outstanding_requests 排队请求的数量，当ZooKeeper超过了它的处理能力时，这个值会增大，建议设置报警阀值为10
zk_packets_received 接收到客户端请求的包数量
zk_packets_sent 发送给客户单的包数量，主要是响应和通知
zk_max_file_descriptor_count 最大允许打开的文件数，由ulimit控制
zk_open_file_descriptor_count 打开文件数量，当这个值大于允许值得85%时报警
Mode 运行的角色，如果没有加入集群就是standalone,加入集群式follower或者leader
zk_followers leader角色才会有这个输出,集合中follower的个数。正常的值应该是集合成员的数量减1
zk_pending_syncs leader角色才会有这个输出，pending syncs的数量
zk_znode_count znodes的数量
zk_watch_count watches的数量
Java Heap Size ZooKeeper Java进程的
配置监控
在各节点操作
（1）、安装依赖包
yum install -y nc
yum install -y zabbix-sender
（2）、用nc获取数据测试

要让Zabbix收集到这些监控数据，有两种方法:
（1）、每个监控项目通过zabbix agent单独获取，主动监控和被动监控都可以。
（2）、将这些监控数据一次性使用zabbix_sender全部发送给zabbix。
这里我们选择第二种方式。那么采用zabbix_sender一次性发送全部监控数据的脚本就不能像通过zabbix agent这样逐个获取监控项目来编写脚本。
首先想办法将监控项目汇集成一个字典，然后遍历这个字典，将字典中的key:value对通过zabbix_sender的-k和-o参数指定发送出去。
echo mntr|nc 127.0.0.1 2181
这条命令可以使用Python的subprocess模块调用，也可以使用socket模块去访问2181端口然后发送命令获取数据，获取到mntr执行的数据后还需要将其转化成为字典数据。
详细代码如下：
#!/usr/bin/env python
""" Check Zookeeper Cluster

注意，有几个地方需要修改：
- zabbix_sender的目录
- zabbix_conf的目录
- jps的目录，在代码126行
（3）、添加可执行脚本
chmod +x /usr/local/zabbix-agent/scripts/check_zookeeper.py
（4）、修改zabbix_agent的配置文件
vim /etc/zabbix/zabbix_agentd.d/check_zookeeper.conf
UserParameter=zookeeper.status[*],/usr/bin/python /usr/local/zabbix-agent/scripts/check_zookeeper.py $1
（5）、重启zabbix_agent
service zabbix-agent restart
