zabbix3.4.8中提示host [4gronghe_110] not found

查看zabbix_agentd.log时出现下列错误

[root@4gronghe_110 ~]# tail /var/log/zabbix/zabbix_agentd.log 
1266:20140523:063554.157 no active checks on server [127.0.0.1:10051]: host [4gronghe_110] not found

出现该错误的原因是一般是zabbix_agentd.conf里面的hostname和前端zabbix web里面的配置不一样所造成的，即在zabbix web页面monitoring->configuration->hosts 页面的name和zabbix_agentd.conf里面的hostname要一样。 

解决方法：

1.查看zabbix_agentd.conf文件中的hostname

[root@zabbixsrv ~]# cat /etc/zabbix/zabbix_agentd.conf | grep hostname
### option: hostname
# value is acquired from hostnameitem if undefined.
# hostname=
hostname=4gronghe_110
### option: hostnameitem
# item used for generating hostname if it is undefined. ignored if hostname is defined.
# hostnameitem=system.hostname
# aliases can be used in hostmetadataitem but not in hostnameitem parameters. 

2.在zabbix web页面monitoring->configuration->hosts 页面更改host name和zabbix_agentd.conf里面的hostname一样。 

3.重新启动zabbix-agent服务

[root@zabbix ~]# service zabbix_agent restart
shutting down zabbix agent: [ ok ]
starting zabbix agent: [ ok ]

4.再次查看日志文件

[root@zabbixsrv ~]# tail /var/log/zabbix/zabbix_agentd.log
