zabbix 3.4监控zookeeper3.4

纸水仙

　　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

　　zabbix_agentd.conf配置文件添加
　　UserParameter=zookeeper.status

,/alidata/summer/check_zookeeper.sh $1
　　
zabbix-web端添加zookeeper模板见附件
