This period of time in the study of Zabbix monitoring, considering a problem, is that when our machines are very few, we can manually add the agent way, one by one to add. So now the demand comes out, if we say that we have hundreds of machines on the network to do, we need to add a host, group, add monitoring template, if a one to add you will be crazy, fortunately, Zabbix automatic discovery function is v
