ZooKeeper监控项
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
编写Zabbix监控ZooKeeper的脚本和配置文件
将这些监控数据一次性使用zabbix_sender全部发送给zabbix。采用zabbix_sender一次性发送全部监控数据的脚本，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

增加脚本可执行权限
chmod +x /etc/zabbix/scripts/zookeeper.py
zabbix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
重新启动zabbix-agent服务
service zabbix-agent restart
制作Zabbix监控ZooKeeper的模板并设置报警阀值
zookeeper.xml(一定是zabbix采集器的方式)
