zabbix3.4 监控 zookeeper

zookeeper 监控要点系统监控 这个监控 linux 系统以及修改 linux 服务器参数即可
内存使用量 ZooKeeper 应当完全运行在内存中，不能使用到 SWAP。Java Heap 大小不能超过可用内存。
Swap 使用量 使用 Swap 会降低 ZooKeeper 的性能，设置 vm.swappiness = 0
网络带宽占用 如果发现 ZooKeeper 性能降低关注下网络带宽占用情况和丢包情况，通常情况下 ZooKeeper 是 20% 写入 80% 读入
磁盘使用量 ZooKeeper 数据目录使用情况需要注意
磁盘 I /O ZooKeeper 的磁盘写入是异步的，所以不会存在很大的 I / O 请求，如果 ZooKeeper 和其他 I / O 密集型服务公用应该关注下磁盘 I / O 情况

ZooKeeper 监控
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 平均延迟 / 最小延迟 / 最大延迟
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 堆积请求数
zk_packets_received 接收到客户端请求的包数量 收包数
zk_packets_sent 发送给客户单的包数量，主要是响应和通知 发包数
zk_max_file_descriptor_count 最大允许打开的文件数，由 ulimit 控制 最大文件描述符数量
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 打开的文件描述符数量
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 follower 数量
zk_pending_syncs leader 角色才会有这个输出，pending syncs 的数量 准备同步数
zk_znode_count znodes 的数量 znode 数量
zk_watch_count watches 的数量 watch 数量
Java Heap Size ZooKeeper Java 进程的

监控脚本

#!/bin/bash

function imok {
        echo ruok|nc 127.0.0.1 2181 | wc -l
