CentOS 7搭建Zabbix3.0.4服务端及配置详解(9)

1.应用场景描述

在目前公司的业务中，有部分ESB架构用ZooKeeper作为协同服务的场景，做好ZooKeeper的监控很重要。

2.ZooKeeper监控要点

系统监控
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
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

3.在各节点包括leader和follower上配置

zook集群的配置请参考centos6.5环境下zookeeper-3.4.6集群环境部署及单机部署详解:

监控原理描述
安装依赖包
yum install -y nc
yum install -y zabbix-sender

4.编写Zabbix监控ZooKeeper的脚本和配置文件

要让Zabbix收集到这些监控数据，有两种方法一种是每个监控项目通过zabbix agent单独获取，主动监控和被动监控都可以。还有一种方法就是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
即需要将这种样式的数据

zk_version3.4.6-1569965, built on 02/20/2014 09:09 GMT

详细代码如下：

增加脚本可执行权限
chmod +x  /usr/local/zabbix-agent/scripts/check_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

4.制作Zabbix监控ZooKeeper的模板并设置报警阀值

问题：

部署上去后发现不出图，查看zoo.cfg文件，发现服务器是通过内外dns解析域名访问的，于是将/usr/local/zabbix-agent/scripts/check_zookeeper.py中监听的localhost改为对应的域名

并且将zabbix-server端监听方式改为dns，重启客户端后，终于出图了
