name: "Install the correct repository" include: "Debian.yml" when: - zabbix_agent_os_family == "Debian" - not (zabbix_agent_docker | bool) tags: - zabbix-agent - init - config - service - debian ``` > 最后的debian是新增的。 3. 修改`dj-wasabi.zabbix-agent/tasks/Linux.yml`，给DOcker增加tags，如下： ``` - name: "Install the Docker container" include: Docker.yml when: - zabbix_agent_docker | bool tags: - docker ``` > 最后两行是新增的。 4. 安装 ``` ansible-playbook -i inventory/zabbix.yml new-zabbix-agent.yml -l 192.168.163.150 --skip-tags "sangoma,debian,suse,windows,docker" ``` > 每次新增zabbix-agent，最后安装完成，重启一下zabbix-proxy，这样proxy会尽快发现agent节点 1. 监控模块 我们采用的是zabbix主动式的监控方式，zabbix-agent主动推送数据给proxy或server，以减少server端压力。 我发现在新的zabbix监控中，还可以检查时间有没有同步。 而且还有磁盘IO的监控，就问你们棒不棒！！！ 很棒！ > 4.4中新的主动式模板中，需要将监控项system.localtime 变为enabled，否则主机的可用性为unknown 主动式的缺点，主机宕机，知道的时间不及时，好像是30分钟。
