43.第35章 Zabbix
一.zabbix 主动与被动监控模式
被动模式：
无论是模式还是被动模式，都是站在zabbix agent角度来说的工作模式，比如被动模式，是说zabbix agent被动的接受zabbix server周期性发送过来的数据收集指令，在被动模式之下，zabbix server会根据主机关联的模板中的监控项和数据采集间隔时间，周期性的打开随机端口并向zabbix agent服务器的10050发起tcp连接，然后发送获取监控项数据的指令，即zabbix server发送什么指令那么zabbix agent就收集什么数据，zabbix server什么时候发送zabbix agent就什么时候采集，zabbix server不发送zabbix agent就一直不响应，所以zabbix agent也不用关心其监控项和数据采集周期间隔时间。
被动模式的优点就是配置简单，安装后即可使用，因此也成为zabbix 的默认工作模式，但是被动模式的最大问题就是会加大zabbix server的工作量，在数百甚至数千台服务器的环境下会导致zabbix server需要轮训向每个zabbix agent发送数据采集指令，如果zabbix server负载很高还会导致不能及时获取到最新数据，但由于无需其他复杂配置，被设置为了默认的工作方式。
主动模式：
主动模式是由zabbix agent主动向zabbix server的10051端口发起tcp连接请求，因此主动模式下必须在zabbixagent配置文件中指定zabbix server的IP或者主机名(必须可以被解析为IP地址)，在连接到zabbix server之前zabbix agent是不知道自己要采集那些数据以及间隔多久采集一次数据的，然后在连接到zabbix server以后获取到自己的监控项和数据采集间隔周期时间，然后再根据监控项采集数据并返回给zabbix server，在主动模式下不再需要zabbix serve向zabbix agent发起连接请求，因此主动模式在一定程度上可减轻zabbix server打开的本地随机端口和进程数，在一定程度就减轻看zabbix server的压力。
二. 如何自定义监控项：
-
先通过脚本或命令获取监控项数据
-
将脚本或命令添加到zabbix agent配置文件中的自定义监控项并重启
UserParameter=n50[*],/bin/bash /data/scripts/n50.sh $1
UserParameter=n51,/usr/bin/python3 /data/scripts/n50.py
UserParameter=tcp_status[*],/bin/bash /etc/zabbix/zabbix_agentd.d/tcp_status.sh $1 $2
-
在zabbix server使用zabbix_get命令测试监控项能否获取到数据
zabbix_get -s 10.0.0.107 -p 10050 -k "tcp_status["tcp_status","ESTAB"]"
-
在zabbix web添加监控项、触发器、图形或者创建模板
-
验证数据
三.zabbix安装
