Zabbix 4.0 API 实践,主机/主机群组 批量添加模板和删除模板

场景

我们日常在管理Zabbix 的时候,经常会需要批量添加模板和批量删除模板,Zabbix页面是提供的批量链接的功能,但是它链接的也只是当前页的主机,我们想扩展这个功能,在链接的时候,可以批量链接整个主机群组,也可以指定链接某台主机,也可以指定链接包含某个字符的多个主机。

提供的功能

查询模板id

select_template(self, template_name)

查询主机群组id

select_group(self, group_name)  

查询指定主机id

select_host(self, hostname='', groupid=''):
  • 当需要查询所有的主机id时

    online_zabbix.select_host()
    
  • 当需要查询指定主机名称id时

    online_zabbix.select_host(name)
    
  • 当需要查询指定主机群组的指定主机名称id时

    online_zabbix.select_host(name,groupid)
    
    hostslist = online_zabbix.select_host('biz')
    print(hostslist)
    

主机链接模板

hosts_add_template(self, template_name, hostname, group_name='')  
  • 当我们想所有的主机链接某个模板,写法 为
    online_zabbix.hosts_add_template('Linux', '')
    
  • 当我们想包含 特定的主机名或者特定的主机关键字的主机链接某个模板 写法为:
    online_zabbix.hosts_add_template('Linux', 'biz') 
    
  • 当我们想特定的主机群组 包含 特定的主机名或者特定的主机关键字的主机链接某个模板 写法为:
    online_zabbix.hosts_add_template('Linux', 'biz','test') 
    

示例:

online_zabbix.hosts_add_template('Linux', 'biz',' test')

主机删除模板

用法同上

hosts_delete_template(self, template_name, hostname, group_name='')
online_zabbix.hosts_delete_template('Linux', 'biz', 'test')

查询指定业务的接入心跳服务(特定场景无需关注)

online_zabbix.statistics_service('djx', 'Heart Monitor',)

查询所有业务接入心跳服务(特定场景无需关注)

online_zabbix.statistics_total()

脚本

基于python3 , 需要安装 requests 模块
