第1章 Zabbix简介及组成

1.1 zabbix简介

zabbix是一个基于web界面,提供分布式系统监视以及网络监视功能的企业级的开源解决方案。它可以监视各种网络参数,保证服务器自动的安全运营,并提供灵活的通知机制以让系统管理员快速定位/解决存在的各种问题

1.1 zabbix组成

zabbix server和zabbix agent,可选组件zabbix proxy

可以通过SNMP、zabbix agent、fping、端口监视等方法对远程服务器或网络状态完成监视/数据收集等功能。支持linux及类unix、windows平台只能安装客户端(被监控)

 

第2章 Zabbix 3.0.13服务端安装

zabbix server3.0无法centos6上进行yum安装,故我们要在centos7上进行yum安装。如果一定要在centos6上进行安装,则强烈建议通过源码方式进行编译安装,同时还需要注意PHP的版本

注意:尽管zabbix server3.0在centos6上不能进行yum安装,但zabbix agent3.0在centos6上是可进行yum安装的

 

第3章 Web页面报错总结

3.1 问题一Zabbix alerter processes more than 75% busy

问题原因:

zabbix服务器邮件进程繁忙导致的,一般是因为设置动作的间隔太短。特殊情况下会产生大量告警,如服务器发几万封邮件过程中,邮件进程发挂了

解决方案:

01.删除数据库解决(风险较大,不建议)

02.修改邮件脚本,将邮件的动作改为打印时间,等待邮件完全释放再改回来,如下

 1 [root@m01 ~]# cat /usr/lib/zabbix/alertscripts/sms 2 3 #!/bin/bash 4 5 echo `date` >>/tmp/sms.txt 

3.2 问题二Zabbix discoverer processes more than 75% busy

问题原因:

01.配置了discovery自动发现任务,配置的每个discovery任务在一定时间内占用1个进程,而zabbix_server.conf中默认配置只有1个discovery(被注释,默认生效)

02.为了快速验证自动发现效果,将discovery任务的"Delay"由默认3600s设置成60s

解决方案:

01.修改配置文件中的StartDiscoverers进程数量,取消其之前的#号并将数值修改为5,最后重启服务

(注:根据系统硬件配置,可以设置成更高的数值,但其范围为0~250)

1 [root@m01 ~]# grep 'StartDiscoverers' /etc/zabbix/zabbix_server.conf
2 
3 ### Option: StartDiscoverers
4 
5 StartDiscoverers=5
6 
7 [root@m01 ~]# systemctl restart zabbix-server.service

02.编写定时任务脚本重启zabbix_server来降低负载

1 [root@m01 ~]# crontab -e
2 
3 @daily service zabbix-server restart > /dev/null 2>&1
4 
5 #计划会每天自动重启Zabbix服务以结束僵尸进程并清理内存等

3.3 问题三Zabbix poller processes more than 75% busy

问题原因:

01.通过Zabbix agent采集数据的设备死机或其他原因导致zabbix agent死掉server获取不到数据

02. server向agent获取数据时时间过长,超过了server设置的timeout时间

解决方案:

01.增加Zabbix Server启动时初始化的进程数量

 1 ### Option: StartPollers 2 3 StartPollers=10 #改成多少取决于服务器的性能和监控的数量,如果内存足够的话可以设置更高 

02.修改模板自动发现规则中的保留失去的资源期间为0

3.4 问题四Zabbix housekeeper processes more than 75% busy

问题原因:

为了防止数据库持续增大,zabbix有自动删除历史数据的机制即housekeeper,而mysql删除数据时性能会降低,就会报错

解决方案:

调整HousekeepingFrequency参数

 1 HousekeepingFrequency=12 #间隔时间 2 3 MaxHousekeeperDelete=1000000 #最大删除量 

3.5 问题五Zabbix server内存溢出,无法启动

问题原因:

zabbix使用一段时间后,再次加入一批交换机监控,zabbix-server将无法启动,查看日志显示如下(提示内存溢出,需调整zabbix服务器配置zabbix_server.conf)

1 2816:20170725:174352.675 [file:dbconfig.c,line:652] zbx_mem_realloc(): out of memory (requested 162664 bytes)
2 
3 2816:20170725:174352.675 [file:dbconfig.c,line:652] zbx_mem_realloc(): please increase CacheSize configuration parameter

解决方案:

 1 vim zabbix_server.conf 2 3 CacheSize=1024M #默认为8M 

3.6 PHP Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 11 bytes)

问题原因:

zabbix某些页面无法打开,查看php日志发现,当访问这个页面时报错内存不足

解决方案:

不清楚是否内存泄露,最简单的方法是调大php进程的可用内存

 1 [root@zabbix-master ~]# grep 'memory_limit' /etc/httpd/conf.d/zabbix.conf 2 3 php_value memory_limit 512M #默认128M
