Zabbix实现故障自愈功能
当zabbix服务监控到指定的监控项异常时，可以通过指定的操作使故障自动恢复
案例：以nginx服务为例,当nginx服务停止时,自动重启服务,实现故障自愈功能#Zabbix Agent 开启远程命令功能 在agent配置中添加AllowKey=system.run[*]、UnsafeUserParameters=1参数 在proxy配置中，将enableremotecommands参数设置为1 [root@ubuntu2204 ~]#grep UnsafeUserParameters /etc/zabbix/zabbix_agent2.conf### Option: UnsafeUserParameters# UnsafeUserParameters=0UnsafeUserParameters=1[root@ubuntu2204 ~]#grep AllowKey /etc/zabbix/zabbix_agent2.conf### Option: AllowKey# If no AllowKey or DenyKey rules defined, all keys are allowed.AllowKey=system.run[*]# Multiple keys matching rules may be defined in combination with AllowKey.# If no AllowKey or DenyKey rules defined, all keys are allowed.#Zabbix Agent 对 Zabbix 用户授权管理权限[root@ubuntu2204 ~]#grep zabbix /etc/sudoerszabbix ALL=(ALL) NOPASSWD:ALL[root@ubuntu2204 ~]#visudo -c/etc/sudoers：解析正确/etc/sudoers.d/README：解析正确[root@ubuntu2204 ~]# getent passwd|grep zabbixzabbix:x:111:116::/var/lib/zabbix/:/usr/sbin/nologin#测试是否成功[root@ubuntu2204 ~]#su -s /bin/bash zabbix -c "sudo systemctl restart nginx"

等一会会发现服务重启，问题被解决
Zabbix 的主动和被动模式工作原理
*主动模式和被动模式都是相对 zabbix agent而言的
被动模式：Zabbix默认是被动模式，如果有100个监控项，被动模式需要 Zabbix Server找 Zabbix Agent要100次主动模式：主动模式是Zabbix Server给 Zabbix Agent发送一个包括100个监控项的任务清单，Zabbix Agent根据任务清单，采集好100个监控项的值，主动汇报给 Zabbix Server这100个监控项，Zabbix Agent主动模式只需要发送一次数据，大大提高了传输效率。注意: 两种模式可以在Zabbix Server上同时存在,可以将一部分监控项设为主动,其它设为被动模式
通信过程
#被动监测通信过程如下:Server打开一个TCP连接Server发送请求agent.pingAgent接收到请求并且响应Server处理接收到的数据关闭TCP连接被动模式每获取一个监控项都需要打开一个tcp连接，这样当监控项越来越多时，Zabbix Server会打开很多端口,就会出现server端性能瓶颈问题。#主动模式监测通信过程如下:zabbix agent 首先向ServerActive配置的IP请求获取active items，获取并提交active items数据值给server或者proxy。zabbix多久获取一次active items？它会根据agent的配置文件中的RefreshActiveChecks的频率进行，如果获取失败，那么将会在60秒之后重试。
主动模式的流程分两个部分:
获取ACTIVE ITEMS列表Agent主动打开一个TCP连接（主动检测变成Agent打开）Agent请求items检测列表Server返回items列表Agent 处理响应关闭TCP连接Agent开始收集数据主动检测提交数据过程
Agent建立TCP连接Agent批量提交items列表收集的所有监控项数据Server处理数据，并返回响应状态关闭TCP连接
注意：Zabbix agent主动模式对应的进程数量只有1个,不能调整Zabbix agent被动模式对应的进程数量默认3个,可以调整

案例：Zabbix Agent 实现主动模式
在 Zabbix Agent 配置主机模式相关配置在 Zabbix Server 创建配置有主动模式监控项的模板关联主动模板至支持主动模式的 Agent 主机注意: 基于原被动模板克隆生成的主动模式模板,不是所有监控项都能改为主动模式,比如agent.ping 监控项如果改为主动模式, ZBX 提示将无法变绿#Zabbix Server 通过 trapper 进程实现主动模式[root@ubuntu2204 ~]#grep StartTrappers /etc/zabbix/zabbix_server.conf### Option: StartTrappers# StartTrappers=5[root@ubuntu2204 ~]#ps ax|grep trapper 978 ?

在Zabbix Frontend上添加主动模式的服务即可
额外提一点：主动模式下Zabbix录取监控数据是并行执行，被动模式下是串行
监控 JAVA 程序
Zabbix 不支持直接监控JAVA应用。如果要监控JAVA程序比如Tomcat等，需要使用 Java gateway 做为代理,才能从JAVA应用中获取数据
Zabbix Java gateway 能过监听10052/tcp 端口实现监控JAVA应用

部署 Java gateway 服务器
Java gateway 是一个独立于zabbix server和 zabbix agent的组件，默认使用端口10052/tcp, 所以javagateway可以是单独的一台服务器，但是也可以和zabbix server或者zabbix agent 共用一台服务器[root@ubuntu2204 ~]#wget https://repo.zabbix.com/zabbix/6.0/ubuntu/pool/main/z/zabbix-release/zabbix-release_6.0-4%2Bubuntu22.04_all.deb--2022-12-27 17:08:54-- https://repo.zabbix.com/zabbix/6.0/ubuntu/pool/main/z/zabbix-release/zabbix-release_6.0-4%2Bubuntu22.04_all.deb正在解析主机 repo.zabbix.com (repo.zabbix.com)... 178.128.6.101, 2604:a880:2:d0::2062:d001正在连接 repo.zabbix.com (repo.zabbix.com)|178.128.6.101|:443... 已连接。已发出 HTTP 请求，正在等待回应... 200 OK长度： 3676 (3.6K) [application/octet-stream]正在保存至: ‘zabbix-release_6.0-4+ubuntu22.04_all.deb.1’zabbix-release_6.0-4+ubuntu22.04_all.deb.1 100%[===================================================================================================================================>] 3.59K --.-KB/s 用时 0s 2022-12-27 17:08:55 (1.65 GB/s) - 已保存 ‘zabbix-release_6.0-4+ubuntu22.04_all.deb.1’ [3676/3676])[root@ubuntu2204 ~]#dpkg -i zabbix-release_6.0-4+ubuntu22.04_all.deb(正在读取数据库 ... 系统当前共安装有 88686 个文件和目录。)准备解压 zabbix-release_6.0-4+ubuntu22.04_all.deb ...正在解压 zabbix-release (1:6.0-4+ubuntu22.04) 并覆盖 (1:6.0-4+ubuntu22.04) ...正在设置 zabbix-release (1:6.0-4+ubuntu22.04) ...[root@ubuntu2204 ~]#apt update命中:1 http://mirrors.ustc.edu.cn/ubuntu jammy InRelease获取:2 http://mirrors.ustc.edu.cn//ubuntu jammy-security InRelease [110 kB]获取:3 http://mirrors.ustc.edu.cn/ubuntu jammy-security InRelease [110 kB]获取:4 http://mirrors.ustc.edu.cn/ubuntu jammy-updates InRelease [114 kB]获取:5 http://mirrors.ustc.edu.cn/ubuntu jammy-proposed InRelease [270 kB] 获取:6 http://mirrors.ustc.edu.cn/ubuntu jammy-backports InRelease [99.8 kB] 命中:7 https://repo.zabbix.com/zabbix-agent2-plugins/1/ubuntu jammy InRelease 命中:8 https://repo.zabbix.com/zabbix/6.0/ubuntu jammy InRelease已下载 705 kB，耗时 2秒 (385 kB/s)正在读取软件包列表... 完成正在分析软件包的依赖关系树... 完成正在读取状态信息... 完成 有 69 个软件包可以升级。请执行 ‘apt list --upgradable’ 来查看它们。[root@ubuntu2204 ~]#apt install zabbix-java-gateway正在读取软件包列表... 完成正在分析软件包的依赖关系树... 完成正在读取状态信息... 完成 将会同时安装下列软件： default-jre-headless openjdk-11-jre-headless建议安装： default-jre libnss-mdns fonts-ipafont-gothic fonts-ipafont-mincho fonts-wqy-microhei | fonts-wqy-zenhei fonts-indic下列【新】软件包将被安装： default-jre-headless openjdk-11-jre-headless zabbix-java-gateway升级了 0 个软件包，新安装了 3 个软件包， 要卸载 0 个软件包，有 69 个软件包未被升级。需要下载 42.2 MB 的归档。解压缩后会消耗 172 MB 的额外空间。您希望继续执行吗？ [Y/n] y获取:1 http://mirrors.ustc.edu.cn//ubuntu jammy-security/main amd64 openjdk-11-jre-headless amd64 11.0.17+8-1ubuntu2~22.04 [41.5 MB]获取:2 https://repo.zabbix.com/zabbix/6.0/ubuntu jammy/main amd64 zabbix-java-gateway all 1:6.0.12-1+ubuntu22.04 [694 kB]获取:3 http://mirrors.ustc.edu.cn/ubuntu jammy/main amd64 default-jre-headless amd64 2:1.11-72build2 [3,042 B]已下载 42.2 MB，耗时 3秒 (13.4 MB/s) debconf: 因为并未安装 apt-utils，所以软件包的设定过程将被推迟正在选中未选择的软件包 openjdk-11-jre-headless:amd64。(正在读取数据库 ... 系统当前共安装有 88686 个文件和目录。)准备解压 .../openjdk-11-jre-headless_11.0.17+8-1ubuntu2~22.04_amd64.deb ...正在解压 openjdk-11-jre-headless:amd64 (11.0.17+8-1ubuntu2~22.04) .......#可以开启自身的JMX功能实现自身的监控(可选)[root@ubuntu2204 ~]#vim /etc/zabbix/zabbix_java_gateway.conf# uncomment to enable remote monitoring of the standard JMX objects on the ZabbixJava Gateway itselfJAVA_OPTIONS="$JAVA_OPTIONS -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=12345-Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false-Dcom.sun.management.jmxremote.registry.ssl=false"[root@ubuntu2204 ~]#vim /etc/zabbix/zabbix_java_gateway.conf[root@ubuntu2204 ~]#systemctl restart zabbix-java-gateway[root@ubuntu2204 ~]#systemctl enable zabbix-java-gatewaySynchronizing state of zabbix-java-gateway.service with SysV service script with /lib/systemd/systemd-sysv-install.Executing: /lib/systemd/systemd-sysv-install enable zabbix-java-gateway[root@ubuntu2204 ~]#systemctl status zabbix-java-gateway● zabbix-java-gateway.service - Zabbix Java Gateway Loaded: loaded (/lib/systemd/system/zabbix-java-gateway.service;
